DIN931
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 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, materials and finishes are available to order as specials, including small volume manufacture, modifications and bespoke parts made to drawings. Minimum order quantities apply.
