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.
Available from Fastenright in sizes M3 to M64, in both A2 and A4 Stainless Steel.
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.
Non-standard sizes and materials are available to order as specials, including custom parts made to drawings.
