ace blind bolt design and manuacture.

e Accu-Lok® blind astening system is

signed specically or use in compos-

structures. It provides a large blind

de upset that distributes the through-

ckness clamping orce o a joint over

arge bearing area. The large blind side

pset enables the astener to exert a

ry high clamping orce to the struc-

re without damaging the composite

aterial. The Accu-Lok II® and Accu-Lok

® are available with the Dryv-Cap™

on-threaded installation system. The

yv-Cap™ is a disposable driver that

ositively engages the driving recess in

e astener and eliminates the wear as-

ciated with conventional drivers.

Alcoa Fastening Systems oers a wide

variety o high perormance blind rivets.

Blind rivets are ideally suited or use

in structures where access is limited.

However, their reliability and ease o use

make them a great alternative to solid

rivets in many dierent applications.

Alcoa Fastening Systems’heritage ex-

ceeds over 50 years in providing a large

selection o high perormance blind

rivets that are the asteners o choice or

countless applications.

The UNIMATIC® blind rivet system is a

general purpose blind rivet or aero-

space applications. The bulbed blind

head, mechanically-locked spindle and

unique hole-illing eatures provide

higher reliability and strength than

comparable blind rivets. This system

meets or exceeds all o the rigorous

design and perormance requirements

detailed in NAS1900, NAS1919, and

NAS1921 specications. The simplied

single action installation o these blind

rivets permits the use o lightweight,

reliable installation tools. The all-alumi-

num version o this system provides ex-

tremely lightweight high perormance,

while the monel and stainless steel

versions o this system provide high

strength perormance even at elevated

temperatures, as well as superb corro-

sion resistance.

The HuckMAX® blind rivet system is a

general purpose blind astening system

that combines important eatures o

structural integrity and installation

convenience. The system meets or

exceeds all applicable requirements o

industry specications NAS1686 and

NAS1687. In addition to high peror-

mance, the design o the HuckMAX®

blind rivet system is such that only one

tool is needed to install any diameter.

This reduces the cost o assembly, and

makes this astener ideal or repair and

modication use as well as new

The Ergo-Tech® blind astening system is

designed or both metallic and compos-

ite structures. It is available in shear and

tension head congurations. Its corebolt

breaks ush with the top o the sleeve in

all grip conditions. The one-piece sleeve

conguration and no threads in bearing

result in high structural integrity and

high-retained clamp-up. Lightweight

ergonomic tools are available to install

the system. The Ergo-Tech is also ideal

or robotic installation.

The Visu-Lok® blind astening system is

designed specically or use in metal-

lic structures. It provides versatility and

security or numerous applications

and assures the highest shear, tensile,

atigue, and sel-locking capabilities.

When installed, it orms a solid, blindside head, with guaranteed minimum

preload levels. The Visu-Lok® II utilizes a

disposable hex drive nut which remains

on the discarded pintail ollowing instal-

lation, and eliminates cam-out condi-

tions or the operator.

The MS blind bolt is designed or both

metallic and composite structures. It is a

high-strength, vibration-resistant, cost-

eective astener designed to meet the

most challenging blind applications.

This amily o blind bolts has been used

successully in many critical areas such

as engine inlets and leading edge

applications.

The TI-MATIC® blind bolt has all o the

beneits o the MS Blind Bolt with the

added advantage o being lightweight

due to its use o titanium materials. The

large bulb that is ormed during installa-

tion makes this astener ideal or use in

composite structures.

The UAB™ blind bolt builds on the prov-

en reliability and perormance o the MS

blind bolt by simpliying the installation

process. One tool installs three dierent

diameters, reducing tooling costs and

acilitating robotic installation. The in-stalled astener provides greater spindle

lushness or improved aerodynamic

perormance and cosmetic appear-

ance. In addition, the blind side bulb

o the astener is enhanced to provide

additional grip overlap and improved

perormance on sloped suraces.

ng Locked luid boss adapters are

signed with a captive lockring that

cures the adapter to the boss and

events loosening or backing-o under

vere vibration, temperature cycling,

or B-nut installation and removal. While

considered semi-permanent, the adapt-

ers can quickly and easily be removed

and replaced. Due to their small enve-

lope, these adapters are signiicantly

lighter than hex unions, resulting in

weight reduction o the hydraulic pack-

age system. Standard tube-end con-

gurations consist o beam seal, ared,

and areless. Variations o the standard

design include reducers, expanders,

port plugs, and solids.

Ring Locked luid boss inserts are

used in initial designs or to repair dam-aged ports. These products are able to

provide high-strength suraces in which

unions are installed. A separate lockring

secures the insert to the boss, thus pre-

venting loosening or backing-o under

severe vibration, temperature cycling, or

tting installation and removal.

Standard ttings are used throughout

the military and commercial aerospace

markets. Straight and shaped ttings

are available in a variety o congura-

tions with both 37° lared and 24°

fareless tube-ends. Other tube-end

congurations include ball-nose, o-ring

seal, pipe, bump, and weldable. Port

plugs, sleeves, nuts, bushings, caps, and

errules are available to complement all

port congurations. Shaped products

include 45º and 90º elbows, tees, cross-

es, swivels, and other unique congura-

tions that meet special customer needs.

Conical or metallic seals eectively

prevent leakage in critical applications.

They elimin ate p otent ial p roble ms

caused by nicks, scratches, imperect

Conical seals are designed to mate

with 37º ared and areless tube-end

congurations.

Alcoa Fastening Systems also designs and

manuactures a variety o special fuid

products that meet specic customer

design challenges. Some o these products

include the characteristic “Ring-locked”

principle. Other products such as low

Keenserts® inserts and studs are

designed to provide high resistance to

torque-out and pull-out loads. Pre-as-

sembled keys are driven down through

the threads o the parent material to

mechanically lock the asteners into

place. The inserts are available with ree-

running threads or with various types

o locking devices including deormed

threads, Vespel™ insert, and beam lock.

The studs provide a nut-end thread de-

signed to transer high axial loads into

weak base materials. The stud or keyed

end is installed into the parent material,

thus eliminating the need or removing

or replacing a bolt.

Kelox® inserts and studs are high-

perormance threaded products that

typically require smaller diameter instal-

lation holes than other solid bushing

inserts and studs. This translates into

overall reduced boss sizes and weight

savings. The Kelox® asteners incorpo-

rate a pair o sel-broaching keys joined

by an integral ring that acilitates the

driving o the keys into the structure.

Ring Locked inserts and studs have

superior torsional resistance in both

hard and sot parent materials. Inserts

are available with locking and non-

locking threads.

Slimsert™ inserts have a thin cross

section, which is ideal or installation

low-prole K-Fast® nut allows or easy

installation in limited access areas.

The unique design o the threads on the

Aero-Lite® and Veri-Lite® astening

systems allow the overall length o the

pin to be reduced while maintaining the

same grip capability and strength

level as those o the Hi-Lok® system it is

based on. This enhancement reduces the

weight o these systems by as much as 15%

or applications where weight is critical.

The Flite-Tite®pin astening system

is designed specically or compos-

ite skin applications where electrical

conductivity is paramount, such as in

applications subject to lightning strikes.

The Flite-Tite® system uses a stainless

steel or titanium sleeve to develop an

intererence t without composite de-

lamination, and provides the grounding

needed through the structure. The sys-

tem is available either with a titanium

pin and nut or lightest weight, or with

an Inconel® 718 pin and nut or highest

strength.

The Hi-Lok® two-part astening system

delivers high-atigue resistance without

sacricing strength in an efcient, de-

pendable, all-purpose astening system.

Installation in difcult access conditions

is no problem with Hi-Lok® and a wide

range o sizes and material combina-

tions make it a versatile solution or

many assembly problems.

In situations where a controlled interer-

ence t is needed, Hi-Tigue® asteners

Alcoa Fastening Systems meet and

ceed the most exacting requirements

the aerospace industry. Alcoa Fasten-

g Systems’designers and manuactur-

g engineers provide the accumulated

oy steel, corrosion-resistant steel,

conel® 718, Waspaloy, titanium, and

her super alloys. From micro-screws

6mm in diameter) to bolts up to 1-1/4

ch in diameter, and in lengths up to 14

ches, this vast product range is avail-

le in both unied and metric sizes.

coa Fastening Systems’ technical,

etallurgical, and manuacturing skills

e applied to produce high-strength

olts, studs, double-ended studs

nd tie-rod bolts. This talent serves

s and nishes used on present-day

rames and engines with asteners

absolute reliability and superior

ength. Depending on choice, con-

derable weight savings, superior

rrosion resistance, and high strength-

-weight ratios may be gained. Con-

urations include hex,12-point, hook,

head, slab head and spline head.

The developme nt o the irst lock bolt

astener was pioneered in the mid

1940s. Since that revolutionary design,

which greatly simpliied the assembly

o structure, Alcoa Fastening Systems

has led the way with innovative designs

that have been instrumental in improv-

ing structural integrity and reducing

manuacturing costs around the world.

Products are available in both unied

and metric sizes. Installation tool sys-

tems are also oered.

NAS lockbolts are available in a num-

ber o materials and conigurations

designed to meet the most demanding

application requirements. The collar,

swaged into the lock grooves o the

pin, orms a high-strength, vibration-

resistant joint.

The GP™ and LGP® lockbolt amilies

improved on the NAS lockbolt amily by

optimizing the lock groove design. This

optimization makes the GP™ and LGP®

lockbolt system signicantly lighter than

comparable threaded astening systems.

The HUCKCOMP® lockbolt astener is

a high-strength, lightweight astener

intended or use in composite material

applications. The anged titanium collar

enhances joint integrity by spreading

a high clamp load over a large area,

thereby reducing the bearing stress ap-

plied to the composite material.

The HUCKTITE® lockbolt system has

our eatures that are especially needed

in composite structure joints: decreased

water absorption, improved uel tight-

driver can remove the astener. The

Torx® and Torx Plus® recesses provide

reduced risk o both recess damage

during installation, and damage to the

structure when asteners are removed.

The conical Connie® Hi-Torque recess

assures positive alignment o tool and

recess at the beginning o installation,

and is ideally suited to handle the stress-

es o hostile environments.

ness, and enhanced atigue peror-

mance and electrical continuity. These

eatures make it the system o choice in the

most demanding composite applications.

The LHP™ lockbolt has all o the

benets o the HUCKCOMP® lockbolt

astener with the added benets o

higher temperature perormance and

enhanced atigue strength. These

bene its are the result o the unique lock

groove conguration and collar design o

this system.

The XPL® lockbolt is the latest addition

to the Alcoa Fastening Systems lockbolt

amily. With a grip range that is more

than twice that o other systems, each

part number can be used in more than

twice the applications. This means ewer

part numbers to inventory. The wide se-

lection o materials and diameters make

the XPL® the most versatile lockbolt

system ever.

The Flite-Tite® sleeved-threaded

lockbolt is designed specically or

composite skin applications where

electrical conductivity is paramount,

such as in applications subject to

lightning strikes. The Flite-Tite® system

uses a stainless steel or titanium sleeve

to develop an intererence t w

Styles include sel-retaining and sel-

wrenching. Custom designs are also

available to meet our customers’exact-

ing requirements.

The selection o recess drives available

on Alcoa Fastening Systems’externally

threaded products is comprehensive.

The popular Phillips® ACR® drive with

its cam-out resistant eatures is just

the beginning. The Torq-Set® recess

astener system provides torque-tight,

tamperproo screws or bolts. The slant-

ed three-wing design o the Tri-Wing®

screw recess ensures reliable insertion

These asteners provide a rigid structural

joint. The radial tightness minimizes

vibration and cyclic atigue loads, and

helps resist shock loads. EDFs are avail-

able in a variety o materials and nishes

or extreme corrosive or high tempera-

ture environments.
