Description
ISO 4762 Socket Head Cap Screw M5x12-A4 — BOLTON SKU 56927.
About the ISO 4762 Socket Head Cap Screw M5x12-A4
This M5 x 12 mm hexagon socket head cap screw in A4 stainless steel follows ISO 4762, the international dimensional standard matching DIN 912. Cap screws of this pattern have a cylindrical head and internal hexagon drive so they can be recessed into counterbores and tightened from directly above with a hex key. Shared M5 dimensions apply: 0.8 mm coarse pitch, 8.5 mm maximum head diameter, 5 mm head height and a 4 mm key. What distinguishes this SKU is the short 12 mm nominal length — a compact choice where the tapped depth is limited or where a longer screw would bottom out or protrude. In A4 (316-type) austenitic stainless steel, the molybdenum addition improves resistance to pitting and crevice corrosion in chloride service, which is why this ISO 4762 Socket Head Cap Screw grade is commonly specified for marine-adjacent and washdown equipment.

Typical applications
Short M5 cap screws like this are used to fasten thin covers, flanges and fittings into shallow tapped holes on housings and manifolds. The 12 mm length keeps the joint compact in tight assemblies, while the socket drive allows torqueing in clusters or recesses that spanners cannot reach.
