ISO 4762 specifies the dimensions and tolerances for metric socket head cap screws (SHCS) with hexagonal sockets. These are commonly called Allen bolts or hex socket screws. They feature a cylindrical head with a recessed hex drive.

What is the head diameter of an M8 SHCS?

Per ISO 4762, an M8 socket head cap screw has a head diameter (dk) of 13.0 mm, head height of 8.0 mm, and uses a 6 mm hex key (Allen wrench).

What is the difference between ISO 4762 and DIN 912?

ISO 4762 replaced DIN 912. They are functionally identical for most sizes, but ISO 4762 is the current international standard. Some minor tolerance differences exist on larger sizes.

What property class are SHCS typically?

Standard socket head cap screws per ISO 4762 are property class 12.9 (Rm = 1220 MPa, Rp = 1100 MPa). Some manufacturers also offer 8.8 and 10.9 versions.

When should I use socket head cap screws instead of hex bolts?

Use SHCS when: (1) space is limited and a low-profile head is needed, (2) the head must be recessed/counterbored, (3) higher strength is required (12.9 vs typical 8.8), or (4) a cleaner aesthetic is desired.
