PREFACE

The Bureau of Indian Standards is the national standards body working on standardization front in this

country. Its object is to promote fhe development and adoption of standards on national and

international basis with a view to facilitate national and international exchange of goods and services.

The standards play an important role in ensuring human safety and health, to safeguard consumers

interests and also have significant bearing on the national and world economy.

To make available the benefits of Indian Standards to the common man, BIS has introduced its

certification marks scheme under the

Bur eau of I ndian Standards Act, 1987.

According to this Act,

quality goods conforming to Indian Standards carry the Standard Mark. This mark is the third party

guarantee for quality of the marked goods. Licences to use the Standard Mark are granted to the

manufacturers using reliable methods of production and quality control subject to overall supervision

by BIS.

At international level, BIS represents India on the International Organization for Standardization

(ISO) and the International Electrotechnical Commission (IEC). BIS participates in most of the

technical committees of IS0 and IEC.

While continuing with the task of standardization, which is a dynamic process, BIS has already

published national standards totalling over 11000 on wide-ranging subjects. Indian Standards are

generally published in booklet form in A-4 and A-5 sizes for any specific product/ aspect. A large cross-

section of the users of these standards have often expressed their desire to have Indian Standards in

certain areas in the form of comprehensive handbooks. It is felt that these handbooks will provide easy

reference and also make Indian Standards more easily accessible to a larger public. Further, the

handbooks shall also help the user in understanding the provisions of the standards which will enable

them to put the standards to better use.

In view of the above,the Bureau of Indian Standards is bringing out a series of handbooks in certain

specific areas and the Industrial Fasteners Handbook is one of this series.

INTRODUCTION

A fastener is a mechanical device used for holding two or more bodies in definite positions with

respect to each other. The fasteners assume great importance as most of the engineering equipment and

machinery are, today, made up of many assemblies, which use fasteners to hold various components

together. Based on the application intended, fastener receives varying degree of built-in precision and

engineering capability. This has been adequately covered in the various national standards on fasteners.

Although, fasteners are low cost items in the assemblies when compared with the the total cost of

equipment, their importance cannot be under-estimated because of the functional role they play. The

fasteners have a wide application in the entire gamut of industry. No wonder, it is said that a fastener is a

connective tissue of the industrial copus. A large cross-section of the users of the standards have often

expressed their desire to have Indian Standards available in a comprehensive form and hence, this

Handbook on Industrial Fasteners has been compiled.

The Handbook on Industrial Fasteners is one of the series of handbooks to be brought out by the

Bureau of Indian Standards. Once published, the Handbook shall fulfil the long felt need for the

availability of Indian Standards on fasteners and related subjects in a comprehensive form.

The Handbook on Industrial Fasteners is being issued in three parts. Part 1 covers standards on basic

features of fasteners, technical supply conditions and raw materials for fasteners. However, the

standards on general engineering materials in use in the fasteners industry have not been covered.

Besides this, Part 1 also covers few general engineering standards and other standards in the related

field.

Part 2 covers the product standards on bolts screws, studs, nuts and washers.

Part 3 covers standards on rivets, pins, nails, keys and keyways, totters, circlips, and set-collars, etc.

The national standards on fasteners have been formulated mainly by the following three Sectional

Committees:

EDC 27 Bolts, Nuts and Fasteners Accessories

EDC 70 Screw Threads

EDC 71 Rivets (since merged with EDC 27)

As an aid to understanding and application of the work of the above three Sectional Committees as

well as to cover other standards on fasteners, standards have also been included from the work of the

following Sectional Committees

EDC 1 Engineering Standards

EDC 11 Machine Tools

EDC 12 Hand Tools

This Handbook is a compilatlon of the national standards in the field of Industrial Fasteners.

Wherever practicable, corrections and amendments to the standards have been incorporated in the text.

The A-4 size standards have been reproduced as it is whereas A-5 size standards have been

recomposed to match the style and format of A-4 size standards in order to haveuniform presentation.

The Handbook has been divided into different sections, each one covering a group of standards on a

specific type or aspect of fasteners. The standards in each section are arranged in numerical order.

Numerical index is provided for the complete Handbook for easy location of a specific standard,

number of which is known to the user. The keyword (descriptors) index is provided at the end for easy

location of a standard, if the subject is known to the user.

This Handbook has been updated till March 1987. However, standardization being a dynamic and

continuous process, users of the Handbook should take into account the fact that published standards

are subject to review and possible revision. It is pointed out that only the latest available edition is the

valid standard.

SPECIFICATION FOR

TINMENS RIVETS

0. Foreword

0.1 This Indian Standard was adopted by the Indian Standards Institution on 14 October 1957, on approval by

the Building Division Council of the draft finalized on 25 June 1957 by the Builders Hardware Sectional

Committee.

0.2 Tinmens rivets are commonly used in light sheet metal work, such as the manufacture of buckets, steel

trunks and fabrication of air-conditioning ducts. As fasteners, they are required to conform to specific

requirements regarding hardness, strength and workability. This standard specifies these requirements and has

been prepared with a view to guiding the consumers in procuring rivets of the desirable qualities suitable for light

sheet metal work. The specification covers rivets having lengths and diameters up to and including 14.3 mm and

7.0 mm, respectively. Large sizes of rivets known as flat head rivets are proposed to be covered by a separate

specification.

0.3 The Sectional Committee responsible for the preparation of this standard has taken into consideration the

views of producers, consumers and technologists, and has related the standard to the prevailing manufacturing

and trade practices followed in the country in regard to the use of fhese rivets. Assistance has also been derived

from printed catalogues of manufacturers of tinmens rivets.

0.4 This standard requires reference to IS : 280-1951 Specification for mild steel wire

tentative).

0.4.1 Wherever a reference to IS : 280-195 1 appears in this standard, it shall be taken as a reference to the latest

version of the specification.

0.5 In pursuance of the decision of the Government of India to introduce uniform system of weights and

measures throughout the country based on the metric system, all dimensions appearing in the standard have been

expressed in metric units.

0.6 For the purpose of deciding whether a particular requirement of this specification is complied with, the final

value, observed or calculated, expressing the result of a test or analysis, shall be rounded off in accordance with

IS

:

2-1949 Rules for rounding off numerical values; the number of places retained in the rounded off value

should be the same as those of the specified value in the standard.

0.7 This standard is intended chiefly to cover the technical provisions relating to the supply of tinmens rivets and

it does not include all the necessary provisions of a contract.

1. Scope

1.1 This standard lays down the requirements regarding material, shape and dimensions, and test for tinmens

rivets of sizes with even designating numbers ranging from 2 to 20 inclusive.

2. Terminology

2.0 For the purpose of this standard, the following definitions shall apply.

2.1

Nominal Diameter of the Rivet -

The diameter of the rivet shank.

2.2 Nominal Length of the Rivet - The length measured from the underside of the head to the extreme end of

the shank.

3. Material

3.1 Mild steel wire used in the manufacture of tinmens rivets shall conform to IS : 280-1951.

3.1.1 The condition of wire selected by the manufacturer shall be subject to the requirements laid down

under 7.

3.1.2 The heat treatment appropriate to the condition of wire used shall conform to that specified under 7.

This Indian Standard was adopted by the Indian Standards Institution on 17 January 1967, after the draft

finalized by the Screw Threads and Fasteners Sectional Committee had been approved by the Mechanical

Engineering Division Council.

0.2 Bifurcated rivets are extensively used in large quantities to fasten many types of materials such as wood,

plastics and leather. The bifurcation is formed by sawing or punching out the slot from a solid riyet.

0.3 For the purpose of deciding whether a particular requirement of this standard is complied with, the final

value, observed or calc&ted, expressing the result of a test, shall be rounded off in accordance with IS

:

3.Foreword

I.1

This Indian Standard was adopted by the Indian Standards Institution on 17 January 1967, after the draft

inalized by the Screw Threads and Fasteners Sectional Committee had been approved by the Mechanical


1.2 Solid-drilled tubular and semi-tubular rivets are extensively used in large quantities to fasten many types of

naterials, such as sheet metal and die-casting. In solid-drilled tubular rivets, the rivet hole is drilled deeper; in

iome cases to almost all length of the shank whereas in case of semi-tubular rivets, the hole when swaged or

mtruded is generally tapered. The use of these rivets is restricted to those applications where they are subjected to

ihear rather than tensile stresses or where either of these stresses is negligible.

2.3 The material for brass rivets shall conform to IS : 320-1962 Specification for high tensile brass rods and

sections

(revised).

3. Dimensions

3.1 The dimensions for solid-drilled tubular rivets shall be as given in Table 1.

3.1.1 The holes in the rivets are drilled up to the head or for a length of 12 mm, whichever is less.

3.2 The dimensions for semi-tubular rivets shall be as given in Table 2.

3.2.1 The holes in the rivets may be made either parallel or tapered as given in Table 2.

4. Workmanship and Finish

4.1 The rivets shall be well finished and free from burrs and harmful defects. The heads and the drilled holes shall

be well formed.

5. Designation

5.1 The rivets conforming to this standard shall be designated by its name, nominal size, length, number of this

standard and the material.

Examples:

a) An oval head solid-drilled tubular rivet of nominal size 4 mm, length 12 mm and conforming to thir

standard, and made from steel shall be designated as:
