Long Leg U-Bolt

A long leg U-bolt is a U-shaped rod with extended threaded legs, used to clamp pipe, tube or round bar to a support. The long legs allow for thicker assemblies or where the fixing point sits further from the clamped item.

A long leg U-bolt is used to clamp a pipe, tube or round section to a support. It passes around the item and through a flat plate or bracket, then takes two nuts. The legs are usually threaded to suit the nuts, and washers are often added under the nuts.

Hot-dipped galvanising gives a thick zinc coating for outdoor and corrosive environments. Plain finish is uncoated and suits dry, indoor use or where painting is planned. PTFE coating offers low friction and some chemical resistance.

This U-bolt is often made in stainless steel 304 or 316 for corrosion resistance. It can also be made in steel for general engineering. Stainless steel 316 suits 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 mill test certificate or certificate of conformance for the material and finish. On receipt, check thread form, leg length, coating thickness if applicable, and that markings match the order.
