Hex Bit Sockets (ISO 1174 (square drive) / ISO 2936 (hexagon key)) are a type of tools used across industrial assembly. Below is the complete size table together with material, standard and application guidance.
What Are Hex Bit Sockets?
Hex Bit Sockets are tools defined by ISO 1174 (square drive) / ISO 2936 (hexagon key). 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 Hex Bit Sockets has its own reference page with the figures for that one configuration.

Pricing
Hex Bit Sockets are supplied to order. Pricing starts from approximately US$1.60 per piece for standard sizes in the catalog specification; final pricing depends on size, material, finish and order quantity (MOQ applies). Submit your exact configuration with the quote form above.

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.
Frequently Asked Questions
Which standard governs Hex Bit Sockets?
