Carriage Bolts

Cup square carriage bolts or coach bolts are designed to fix metal components like hinges and pad bolts to timber. The square under the head is designed to locate in the fixture and prevent the bolt from turning when tightening the nut. Available in Bright zinc plate and Stainless steel, the BZP range is supplied with nuts but the stainless steel range is not. We would also recommend a washer under the nut which are supplied separately. Please be aware that longer sizes may not be fully threaded, they may have a plain shank like a bolt, if this is a issue please contact us prior to ordering.

Diameters available: M5 M6 M8 M10 M12 M16.   DIN 603, standard Metric course thread.
