DIN 912 Hexagon Socket Head Cap Screws

DIN 912 Hexagon Socket Head Cap Screws are metric socket head cap screws with a cylindrical head and internal hexagon drive. They are commonly identified in international purchasing markets as socket head cap screws, Allen socket cap screws, or simply socket cap screws. DIN 912 is associated with ISO 4762, which defines the dimensional characteristics of this fastener type. The internal hex drive allows the screw to be installed where external wrench access is limited.

The cylindrical head and relatively small external profile make these screws particularly useful for compact mechanical assemblies and counterbored holes. They are commonly specified in machinery, automation equipment, fixtures, tooling, robotics, electrical equipment, and general engineering assemblies. Metric sizes cover a broad range, with commonly supplied dimensions extending from small machine sizes through large industrial diameters.

DIN 912 socket head cap screws are available across several commonly specified strength classes and stainless steel grades, depending on the material and application requirements. Carbon and alloy steel versions are commonly supplied in grades such as 8.8, 10.9, and 12.9, while stainless steel versions include A2 and A4 grades. Surface finishes can include plain, black oxide, and zinc-plated options depending on material and purchasing requirements.

For industrial buyers, this product is generally purchased by standard, nominal diameter, length, material, strength class, and finish. ChinaBolts can support standard product sourcing as well as bulk requirements for distributors, OEM buyers, machinery manufacturers, and industrial purchasing teams.
