Quality above all else

Our key focus is always on quality and we pride ourselves on the accuracy and consistency of our tooling which results in reliable and repeatable fastener production.

We can provide almost any thread form and pitch across our product range and offer a regrind service for both flat and circular dies.

We’re committed to excellence

Great quality tooling and customer satisfaction is at the heart of our business. Everyone, from our highly trained engineers and office management team to our apprentices, work to deliver the best possible customer experience.

A comprehensive product range

With unique specialised manufacturing techniques honed over decades, we offer a comprehensive product range including flat dies, cylindrical dies, axial rolls, tangential rolls and radial rolls. These products cover all standard UNJ, UN, MJ, ISO, BSP, Whitworth, Trapezoidal and Acme forms. We can also produce tools with forms conforming to customer drawings where required, and offer a comprehensive regrind service. 

For applications demanding rapid turnaround, use our readily available stock. We maintain a wide blank inventory in a variety of sizes and hardness specifications that are ready to grind.

Regrind specialists

To help you with return on investment from your tool purchases, we can regrind your used flat or circular dies. We will regrind dies manufactured by GAPS or by third parties and are able to convert from one pitch / form to another when required.

If your dies have been damaged whilst in production, this is no problem, we have the ability to reduce diameters or face widths accordingly.
