A2 stainless steel coach bolts are known as carriage bolts or cup square hex bolts.
These feature a sleek round head with a square base to ensure secure fastening, requiring nuts to be ordered separately.
They are offered in multiple sizes, all with standard metric coarse threads.
A2 stainless steel is often referred to as 304 or 18/8 Stainless. 18/8 actually refers to the amount of chromium and nickel in the alloy - 18% chromium and 8% nickel.
A2 stainless is the most common type of steel used for the manufacture of fasteners and is suitable for general use.
