Dog Bolt

A dog bolt is a threaded fastener with a wing nut, often used for temporary or adjustable clamping. It can be tightened by hand without tools.

A dog bolt often clamps two parts together in temporary or adjustable joints. It usually comes with a wing nut for hand tightening, and it can be matched with a washer.

Dog bolts are often made in steel or stainless steel. Steel types may be zinc plated for mild corrosion resistance, while stainless steel is chosen for wet or outdoor conditions.

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

Ask for a certificate of conformance and a mill test certificate for the material. On receipt, check the wing nut turns freely and the thread is clean. Verify the bolt length and diameter match the order.
