Leitech Instruments ApS Leitech Instruments ApS is aDanish-owned company thatproduces and markets the patented and award-winningSystem Leitech worldwide.
System Leitech is a thread con-trol system for internal threads,which measures the internalthread size and depth in oneoperation.This instrument is the onlythread gauge of its kind in theworld that measures the threadsize and depth in one operation.This gives the user an accurateand reliable measurement, andat the same time provides time-saving of up to 70%, comparedto traditional thread gauges.
Today, the Leitech System is thestandard tool for a number of leading companies worldwide.Therefore gauges are stocked inall international standards suchas ISO, ANSI, JIS, STI etc.Available in dimensions from 2-22MM/2-56 - 7/8", with spe-cial tolerances and leads in accordance with your require-ments and standards.
All gauges are available with acertificate.
In order to meet ever-increasingdemands for quick delivery, wealways have more than 2000 pieces in inventory.
The Leitech gauge has beenawarded with the Danish DesignCouncils Prize.

The Hi-resolutionThread Gauge:Is used in the same way as theCombi Gauge, but with 0.1mmor .005 resolution per division fordepth. Also equipped with alocking device that allows themeasuring sleeve to be lockedat the depth reading, or at a preset depth. The placement ofthe thread hole to be measuredis not always directly visible tothe controller and the reading ofthe scale is therefor difficult.The locking device on the Hi-resThread Gauge makes it possibleto read the scale after the mea-surement has been taken.
The Combi ThreadGauge:To control the thread tolerance,the Leitech Combi ThreadGauge is used in the same wayas any normal double-endedthread gauge.As the GO side is inserted intothe thread hole, the telescopingmeasuring sleeve retreats intothe aluminum body, providingthe user with an accurate depthreading of 0.5mm or .025" reso-lution per division.The NOT GO side is used in aconventional manner.
The Traditional Thread Gauge:A normal double-ended threadgauge.
Thread Inserts:Exchangeable on all gauges.

5 advantages of theLeitech insertThe same insert is used in all our thread gauges.
Quick and easy replacement of aworn out insert.
The inserts are hardened andtempered to 62+/- 1HRc.
Our inserts are up to 100% lon-ger, which gives a maximumwearability and the longest life atno extra cost. The control of pitch errors is also optimised.
All Leitech Gauges with a pitchdiameter larger than 0,8 mmhave the crest of the first fullthread on Go according toFederal Standard H28/6. Thismeans that the distance fromthe thread member from face tothe crest of the first full thread is0,5 pitch with a tolerance of 0,06pitch.This provides the user with anaccurate depth reading, which isnot possible without this. Theuse of traditional thread gaugeswill often provide the user with awrong measuring of the depth.

Technical infoIt is Leitechs objective to giveour customers a maximum wea-rability on all our inserts.Therefor our production alwaysaims at the higher level of the tolerance area.To ensure this objective, our pro-duction usesReishauser thread machines at20°C ±0,5.The Quality Section also worksby 20°C ±0,5.
Instead of investing in a newcomplete gauge every time agauge is worn out, the inserts onthe Leitech gauge are of a spe-cial taperlock design, which canbe easily replaced with a remo-val sleeve tool that can be deli-vered from Leitech.

A new gauge in approx. 2 min.!Instead of investing in a new complete gauge every time a gauge isworn out, the Leitech advantage is that you merely replace theGO/NOT GO insert.
Exchanging the insertsand calibration
Slide the Member RemovalSleeve over the gauge memberto be replaced (Green/Go &Red/Not Go).
Thread the nut on to the gaugemember.
Tighten the nut against theMember Removal Sleeve.
Wrench the gauge member fromthe handle.
Insert the new gauge member.Tap against a soft surface toseat the gauge member into thehandle.
Loosen the two locking screwson the handle with an Allenwrench.
Dial the pitch on the CalibrationMaster. Place the Go end of thegauge into the appropriate sizehole. Grasp and turn the Not Gomember and line up the CombiGauge measuring scale at the.400" (inch) or 10mm (metric)line.
Re-tighten the locking screwsfinger-tight. The Combi Gauge isnow set at the correct calibrationlength (X) for accurate functionalthread depth measurement.
Follow points 1-8.At point 5 the GO insert is fittedinto position with the use of aplastic hammer.
It is so simple - a new gauge - quickly and inexpensively.

Save 17% on MachineHours and ToolConsumption:Companies that drill and taplarge quantities of threaded holes that are 15% to 40% dee-per than necessary to meetdepth requirements are creatingadditional expense! Tool wearand breakage plus machine timeincreases dramatically.
If your company produces 1000holes per day, and if - for goodmeasure - they are just 1,7mmto deep, this means that in ayear a surplus of 374 mtrs ofthread is cut.How much does 374 mtrs threadcost?
The Leitech Combi Gauge al-lows your machinist to adjustdrilling and tapping depths pre-cisely at set-up time. In additionthe operator can monitor thisdepth as the parts are produced.
Reduce Quality Control Time by 45%:The Leitech Combi Gauge al-lows you to qualify your mini-mum GO thread size and length- all in one operation. Fast, andvery cost effective. The measu-ring sleeve allows direct readingof the length when the gauge isfully inserted into a thread hole.
Tests with an engine block with99 threaded holes demonstra-ted how much time that SystemLeitech saves.
In a V12 engine block from oneof Europe's leading car manu-facturers 99 threaded holes in 4thread sizes were measured andinspected for tolerance andlength.
Using conventional gauges theinspection time was:
71 minutes.
Using the Leitech CombiGauges the inspection time was:
39 minutes.
This represents a reduction of 45% of the original time. Theprecision of Leitech and the direct reading made it possibleto meet increased quality de-mands.
Reduce your number of gauges by 72%:7 Leitech Combi Gauges are allan American automotive plantneeds for the overall control of a4 cylinder, 16 valve engine with103 threaded holes.
An industry that uses conventio-nal gauges normally requiresindividual gauges for the inspec-tion of each thread hole depth.This means that it is necessaryto work with a large number of different gauges. However,many gauges mean unneces-sary costs for the gauge stockand an increased risk of humanerror.
As one Leitech Combi Gaugecan measure all thread lengthswithin its range, the number ofgauges can be reduced con-siderably when Leitech is intro-duced.
Often a single Leitech CombiGauge can replace several diffe-rent conventional gauges with filed notches indicating mini-mum thread depth.This results in less money tiedup in gauges and fewer errors.

CALIBRATION OF THE DIGI GAUGECalibration is made by the included adjusting piece. Beware that the adjusting piece is marked with the pitch equivalent to the threaded insert mounted in the gauge.
Switch on the DIGI Gauge and set measurement for mm or inches. Then hold the adjusting piece firmly against the end face of the “go” insert and the contact face of the measuring sleeve. Briefly press the button marked “set”. The digi gauge is now correctly calibrated to zero.
