Square U-Bolt

A square U-bolt is a U-shaped bolt with square bends. It holds square or rectangular sections against a surface.

A square U-bolt clamps square section bar, timber or a rectangular part to a flat surface. It takes a nut and often a washer of the same thread. The square bend holds the clamped part against rotation.

This kind of part is often made in steel or stainless steel. Steel grades can be coated for corrosion protection. Stainless steel gives good corrosion resistance without a coating.

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 for the material and dimensions. On receipt, check the bends for cracks, the thread for damage, and the overall shape for squareness. Confirm the dimensions match your order.
