M8 Coach Bolt

Coach 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 head locks into wood or metal, preventing rotation during installation, which allows easy one-sided fastening.

Supplied with the correct nut and a smooth round head that allows for a flush finish. A head 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 and sees these coach bolts widely used.

Manufactured from mild steel with a bright zinc plating for medium resistance to corrosion. Used by both DIY enthusiasts and professionals alike across many sectors and known in the trade as carriage bolts, coach bolts, cup square carriage bolts.
