Unifix Pack M12 BZP CUP Square Bolt & & NUT

This pack contains two M12 x 240mm cup square bolts with nuts, supplied with a bright zinc plated finish. Commonly known as carriage bolts, these fixings are designed for use with timber connections or to secure metalwork where a flush finish is preferred.

Builders and installers frequently use these bolts for applications such as fitting timber joists, securing post supports, or assembling outdoor structures. The square shank helps prevent turning during tightening, making installation straightforward when access to the bolt head is limited.
