Hexagon Bolts (DIN 931)

SKU: BPS15 Category: Brand:

Hexagon Bolts (DIN 931)

Hexagon Bolts are created to DIN 931, and are a partially threaded fastener with a hexagon-shaped head that is usually fixed with a spanner or socket tool.

Hosting a machine thread, these bolts are suitable for use with either a nut or within a pre-tapped hole.

Materials can include various grades of steel, including Grade 5 (5.6), Grade 8 (8.8), Grade 10 (10.9) and Grade 12 (12.9) with zinc plating, zinc and yellow, galvanising or self colour. They are also available in A2 and A4 stainless steel, with other materials available to order.

As standard, they are available in sizes from M3 to M64, with non-standard sizes and threads – such as UNC, UNF, BSW and BSF – all possible to order.

Please contact us with your requirements to further your enquiry.
