Assembly & maintenanceInstalling and servicing the fasteners in this catalog.
Typical applications
calibrating to a schedule and after any drop
tightening in a smooth pull, not in jerks
selecting a wrench whose mid-range covers the working torque
winding a click wrench back to its lowest setting for storage
driving and releasing fasteners on the bench and in the field
Where to use something else
Do not use a torque wrench to loosen a seized fastener; a single over-range pull puts the calibration out and every joint tightened afterwards is wrong.
Customize the parameters below — every spec field is editable, and the drawing redraws to match the values you choose. Changing the size will snap the other fields to that size's standard values; you can then override any individual value.

Torque Wrenches for Fastener Tightening (ISO 6789 (hand torque tools — requirements and test methods)) are a type of tools used across industrial assembly. Below is the complete size table together with material, standard and application guidance.
What Are Torque Wrenches for Fastener Tightening?
Torque Wrenches for Fastener Tightening are tools defined by ISO 6789 (hand torque tools — requirements and test methods). They are selected by nominal size and the dimensional characteristics shown below, and are available in a range of materials and finishes to suit the application and environment.
Materials & Finishes
Common materials include carbon steel (typically zinc plated or hot-dip galvanized), hardened or case-hardened steel where wear matters, and stainless steel A2 (304) or A4 (316) for corrosion resistance. Specify the material, hardness where relevant, and the surface finish appropriate to your application and environment.
Specification Guides
Each size, material and standard of Torque Wrenches for Fastener Tightening has its own reference page with the figures for that one configuration.

Custom manufacturing · Made to drawing
Need a torque wrenches for fastener tightening outside the standard range?
A non-standard fastener tool is quoted from the drawing; where one already exists in the catalog, the special is usually a variation on its tooling.
Minimum order from 2,000 pieces; samples within 7 days of drawing approval.
This part is cold-formed, threaded, heat-treated and finished in-house. The stages below are where its class and finish are actually decided.
01
Cold heading
Wire rod is drawn to size and cold-formed into blanks. Forming rather than cutting keeps the grain flow continuous around the head, which is where a bolt is most likely to fail.
Head dimensions and under-head radius checked at set-up and per shift.
02
Thread rolling
Threads are rolled between hardened dies rather than cut. Rolled threads are stronger in fatigue than cut threads and hold pitch and flank angle far more consistently across a batch.
Go / no-go ring gauges to ISO 965 tolerance class 6g.
03
Heat treatment
Quench-and-temper brings carbon and alloy steel to the property class ordered — 8.8, 10.9 or 12.9 — with the furnace charge tracked so a finished lot can be traced back to it.
Core hardness and tensile tested per lot to ISO 898-1.
04
Surface treatment
Zinc, zinc-nickel, hot-dip galvanizing, black oxide, phosphate and Dacromet, selected against the service environment rather than against the price list.
Coating thickness and neutral salt spray hours to ISO 9227.
