When a loose or vibrating pipe threatens your plumbing run, HVAC line, or structural conduit, the right U-bolt clamp makes all the difference. These zinc-plated BSP standard pipe U-clamps are engineered for makers, maintenance professionals, and workshop builders who need a reliable, corrosion-resistant fastening solution across a wide range of nominal bore sizes.
Each set consists of a formed steel U-bolt, matching hex nuts, and flat washers, all finished with a zinc electroplate coating for rust resistance. The size dimension refers to the nominal bore (inner pipe diameter), with available cross-section profiles in both straight and cross-shaped configurations. Sizes span from 20×20mm (~¾"×¾") up to 90×90mm (~3½"×3½"), covering the most common BSP pipe schedules.
Typical applications include securing copper or steel water supply pipes to joists and wall brackets, clamping conduit runs in electrical installations, and anchoring structural tubing in DIY racking or frame builds — all scenarios where a BSP nominal bore pipe U-clamp with nuts and washers delivers a clean, code-friendly finish.

Match the size to your pipe's BSP nominal bore — not the pipe's outer diameter. For example, a ½" BSP nominal bore pipe has an outer diameter of approximately 21.3mm, so you would select the 20×20mm variant. If you are unsure, measure the pipe's outer diameter and cross-reference it against a BSP nominal bore chart before ordering.
The straight variant has a standard U-bolt profile suited for clamping a pipe against a flat surface or bracket in a single direction. The cross-shaped variant features a perpendicular backing plate or saddle that allows the clamp to be mounted at a corner or junction point, making it ideal for securing pipes at right-angle intersections or to structural members.
The zinc electroplate finish provides moderate corrosion resistance suitable for sheltered outdoor environments, such as under eaves or inside utility enclosures. For fully exposed outdoor installations or coastal environments with salt air, consider additional protective coating or stainless steel alternatives, as zinc plating alone may not provide sufficient long-term protection in harsh conditions.
Yes. These U-clamps are compatible with copper, steel, and rigid plastic (PVC/CPVC) pipes of the corresponding BSP nominal bore size. When clamping copper or soft plastic pipes, take care not to overtighten the nuts, as excessive torque can deform the pipe wall. Use the flat washers included in the set to distribute clamping load evenly.
The U-bolts are formed from steel rod and are designed for standard pipe-securing duties in plumbing, HVAC, and light structural applications. Load capacity depends on the rod diameter of the specific size variant, the mounting substrate, and the number of clamps used. For heavy or pressurised pipe runs, space clamps at intervals recommended by your local plumbing or building code, and consult a qualified installer if in doubt.
Yes — each set includes one U-bolt, two hex nuts, and two flat washers, which is everything required to complete a single clamp point. You will also need a suitable backing plate or mounting bracket (sold separately) and a spanner or socket set to tighten the nuts to the appropriate torque for your application.
The U-bolt threaded legs and supplied hex nuts follow the thread specification matched to the BSP nominal bore standard for each size. The exact thread pitch and diameter vary by size variant — please refer to the variant options or contact us to confirm the thread specification for your chosen size before ordering.
