U-Bolt with Seat

A U-bolt with seat is a U-shaped bolt with a saddle or seat that fits over a pipe or tube. It clamps the pipe to a support.

A U-bolt with seat clamps a pipe, tube or round section against a flat surface. It often fits around a pipe and through two holes in a bracket or channel. The U-bolt can be matched with two nuts and often two washers of the same thread and class.

Hot-dipped galvanising gives a thick zinc coating for outdoor and corrosive environments. Plain finish has no coating and is for dry, indoor use. PTFE coating gives low friction and some chemical resistance.

This kind of U-bolt is often made in stainless steel 304, stainless steel 316 or steel. Stainless steel 316 gives the best corrosion resistance for marine or chemical exposure.

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 material test certificate. On receipt, check the thread, the dimensions and the coating for damage.
