Stainless Steel Hexagon Bolts (DIN 931)

SKU: SSF05 Category:

Stainless Steel Hexagon Bolts to DIN 931

Stainless Steel Hexagon Bolts are created to DIN 931 and are also often referred to as Hex Head Cap Screws.

Fastened using a spanner or a socket, these bolts host a machine thread meaning that they are suitable for use with a nut or within a pre-tapped hole. They are partially threaded with a plain portion on the shank leading up to the head.

Stocked from M3 to M64 in both A2 and A4 stainless steel, and are also available to be ordered in a range of materials – such as steel, brass, aluminium and titanium – as well as a range of threads including UNC, UNF, BSW and BSF.

Please contact us with your requirements to further your enquiry.
