M5X0.8 Carriage Bolt - A2 Stainless DIN 603


Carriage bolts have a small square shoulder under the head that fits into a prepared square-bored hole. The self-locking square neck prevents rotation, holding the bolt in place while tightened with a mating nut.

A large, smooth domed head creates a safe finish installation, the absence of a drive socket prevents debris build up.


Also known as Round head square neck bolt or mushroom head bolt.


Material: A2 / SAE Type 304

A2 Stainless carriage bolts are commonly used in damp environments for corrosion resistance, popular across a wide range of industries: automotive, motorsport, industrial machinery, architectural finish work, agriculture, food processing, clean energy, etc.

For any application involving marine (salt water), use A4 / 316 Stainless Steel material, available as a special order.
