Coach Bolt M12 x 180mm Bright Zinc Plated (Pack of 8)

Summary

A pack of 8 M12 x 180mm coach bolts, also known as carriage bolts, featuring a domed head and square neck designed to bite into timber and resist rotation during tightening.

Features

• Domed round head provides a neat, snag-free finish on the visible face of the joint.

• M12 thread diameter suits standard M12 nuts and washers for robust structural connections.
• 180mm length provides ample thread engagement for thick timber sections and laminated beams.
• Pack of 8 bolts offers a convenient trade quantity for site and workshop use.
