Precision Broaching for High-Performance Socket Set Screws

A key stage in the production of many socket set screws is broaching, the process used to create the internal drive profile. At Pattern Fasteners, we produce hexagon, hexalobular and bespoke non-standard socket profiles using a combination of traditional press broaching, rotary (wobble) broaching and shaping tools. By selecting the most suitable broaching method for each application, we achieve exceptional accuracy, repeatability and a consistently high-quality finish.

Every broached profile is manufactured to ensure precise tool engagement, reliable torque transfer and long-lasting performance. Whether producing a standard hex socket or a completely bespoke internal drive, our experienced team has the expertise and equipment to deliver components that meet the highest manufacturing standards.

With over 45 years of experience in manufacturing special and non-standard fasteners, we understand that no two projects are the same. That's why we work closely with our customers to produce socket set screws tailored to their exact drawings, specifications and performance requirements.

Whether you require standard socket set screws, bespoke broached profiles or a completely custom fastening solution, our experienced team is here to help. Get in touch today to discuss your next project, we'd love to hear from you!
