Historic Threads is a UK-based specialist engineering company dedicated to the manufacture and supply of traditional threaded fasteners made to original British and historic standards. The business exists to serve engineers, restorers and manufacturers who need components that modern metric ranges simply cannot replace.

Focused on quality, accuracy and authenticity, Historic Threads produces a wide range of nuts, bolts, studs, screws, washers and bespoke threaded components to specifications such as Whitworth, BSF and BA. These thread forms remain essential for the restoration and maintenance of heritage machinery, classic vehicles, vintage equipment and specialist engineering projects where originality and correct fit are critical.

All components are manufactured in-house in the UK using a blend of modern CNC machinery and traditional manual engineering techniques. By producing fasteners from round bar material rather than standard hex stock, Historic Threads is able to deliver stronger, more consistent products with precise thread geometry. This approach ensures reliability in use and confidence for customers working on high-value or irreplaceable equipment. Material certification can also be provided where required.

The company’s growing product range includes traditional hex nuts, studs, castle nuts, threaded rivets, slot-headed screws and specialist washers that are increasingly difficult to source through mainstream suppliers. In addition to standard sizes, Historic Threads offers a bespoke manufacturing service, allowing customers to commission custom threaded components for one-off applications or small production runs.

Alongside fasteners, Historic Threads supplies complementary engineering items and provides subcontract machining services, supporting customers who require specialist turning or threading expertise. Orders are fulfilled across the UK, with a focus on dependable service, clear communication and consistent quality.

At its core, Historic Threads combines traditional engineering values with modern precision. The company exists to preserve compatibility with historic standards while meeting the expectations of today’s engineers, delivering fasteners that fit correctly, perform reliably and respect the integrity of the original design.
