M18 x 40mm Hex Socket Cap Screw (DIN 912) | Marine Grade A4 Stainless Steel

Developed for rail and transport maintenance, this M18 x 40mm hex drive cap screw gives a secure hex socket fixing with a 18mm head height for machine and equipment assemblies.

The A4 stainless steel equivalent to 316 material specification is well suited to attaching steel brackets, particularly where strong thread engagement is required from a compact socket head fixing. The A4 stainless specification makes this a useful choice for harsher environments compared with standard indoor fixings.
