House-Shape U-Bolt

A house-shape U-bolt is a U-shaped rod with threaded ends and a flat or shaped saddle. It clamps a pipe or tube to a support.

A house-shape U-bolt clamps a pipe or round section against a flat surface. It takes two nuts and often a plate or bracket of the same thread and finish.

Hot-dipped galvanising gives a thick zinc coating for outdoor and wet service. Plain finish is bare metal and suits dry indoor use. PTFE coating gives a low friction surface and helps resist chemicals.

This kind of bolt is often made in stainless steel 304, stainless steel 316, high tensile steel or mild steel. Stainless steel 304 and 316 resist corrosion, with 316 giving better resistance to chlorides. High tensile steel carries higher loads, while mild steel suits general duties.

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 dimensional check report. On receipt, check the thread condition, the leg length and the coating for damage. Confirm the material and finish match your order.
