Coach Bolts (Cup Square)

We supply coach bolts, also known as cup square bolts or carriage bolts, in metric sizes from M5 to M12. Available in zinc plated steel, A2 stainless steel and brass, these bolts are widely used in timber construction, fencing and general assembly applications.

The domed head and square neck design prevents rotation during installation, making coach bolts ideal for fastening wood and structural components. Bulk quantities available with fast UK delivery.
