Quarry Bolt

A quarry bolt is a heavy duty fastener designed for use in quarrying and mining equipment. It often has a large head and a thick shank to withstand impact and vibration.

A quarry bolt holds wear plates and liners in crushers and screens. It often takes a nut and washer of the same thread and class. A spanner or impact wrench sets it.

This kind of bolt is often made in steel. Steel provides the strength needed for high load applications. It can be coated for protection against corrosion.

This is a general guide to checking this kind of part. It says nothing about any supplier's parts.

Ask for a mill test certificate to confirm the steel grade and mechanical properties. On receipt, check the dimensions, thread and head markings. Look for cracks or other defects that could affect performance.
