Imperial Allthreads (Threaded Rod)

Imperial threaded rod, often referred to as allthread or studding, is used for bracing, suspending, joining and general construction applications where traditional imperial thread systems are required. It provides a strong, versatile fixing solution that can be cut to length and used with standard imperial nuts, washers and brackets. This range covers established thread forms including Whitworth, UNC, UNF and BA to match legacy equipment and heritage engineering.

Technical Information

Imperial threaded rod follows long‑established British and American thread standards, including Whitworth (BSW), UNC, UNF and BA. Each thread form has its own geometry, pitch series and fit classes, ensuring compatibility with traditional imperial nuts, washers and couplers used in legacy machinery, plant, structures and specialist equipment.

More information

Imperial allthread is widely used in restoration, maintenance and heritage engineering where original imperial fasteners must be matched. Coarse and fine thread series are available across Whitworth, UNC and UNF, while BA cover finer and miniature applications in instrumentation, electrical work and precision assemblies.
