Product Description
M12 A2 Stainless Steel Hexagon Head Bolts With Shank – DIN 931
These M12 hexagon head bolts are manufactured from A2 stainless steel and feature a partially threaded shank to the traditional DIN 931 dimensional pattern. They have a standard M12 x 1.75mm metric coarse thread and are available in lengths from 40mm to 250mm.
The unthreaded section of the bolt provides a plain bearing surface through the joint, making these bolts suitable for machinery, equipment, fabrication, construction and general engineering applications where a part-threaded fastener is required.

A2 stainless steel
A2 stainless steel provides good resistance to corrosion in many indoor and general outdoor environments without requiring an additional protective coating. For coastal, marine, swimming-pool or other chloride-rich environments, A4 stainless steel is normally the more suitable choice.
Stainless-steel threads can be susceptible to galling during assembly. Use clean threads, an appropriate anti-seize compound and controlled installation speeds, particularly when fitting stainless nuts.
