M8 x 35mm Carriage bolt (Coach Bolt), A2 (304) Stainless Steel, DIN 603

Corrosion Resistant Carriage Bolt

Carriage bolt with a smooth head, no drive recess for security, and a square neck beneath the head that prevents rotation when tightened from the back.

The square neck under the rounded head locks into wood or metal, preventing rotation during installation, which allows easy one-sided fastening.

The smooth round head allows for a clear finish and with no drive recess restricts the bolt from being removed or tampered with without clear access to the back.

This adds an element of security to applications where disassembly should be restricted.

A combination that sees these coach bolts widely used and being manufactured from A2 stainless steel makes them versatile for both internal and external uses.

Known in the trade as carriage bolts, coach bolts, cup square carriage bolts, and used by DIY enthusiasts and professionals alike.
