Hexagon Bolts (DIN 931)

SKU: BPS15 Categories: ,

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 from Fastenright.

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.
