Unifix Pack 4 M12 x 75mm BZP CUP Square Bolt & NUT UB3178

This pack contains four M12 x 75mm cup square bolts with matching nuts, finished in bright zinc plating for general fastening applications. The bolt features a square neck under the dome head, allowing it to grip into wood or metal and prevent turning during tightening.

Commonly used for joining timber or securing steel fittings, these bolts are suitable for a range of on-site assembly and repair tasks. The pre-packed format is convenient for small to medium projects, providing the necessary fixings for reliable connections in construction, joinery, or non-structural metalwork.
