FAQs for U-Bolts

What is a U-bolt used for?

A U-bolt is a U-shaped fastener with threaded ends, designed to clamp pipes, tubes, or round bars to a surface or bracket which sees them used in heavily construction.

How do I measure a U-bolt correctly?

Measure the inside width (between the legs) to match your pipe’s outside diameter as this will ensure the U bolt fits over the pipe. Also, measure the overall length / inside height to leave enough thread when it clears and feeds through the mounting surface.

What does “ZP” mean on a U-bolt?

“ZP” stands for zinc plated, meaning the steel is coated for moderate corrosion protection. Zinc plating suits indoor or sheltered outdoor environments in the UK.

Can U-bolts be reused?

Re-using U-bolts is not recommended, especially in safety-critical applications. Threads may stretch or corrode, reducing load capacity.
