Our Step-By-Step Process



Our process begins with a meeting between our experts and your team. This meeting is designed to help us understand your specific needs and requirements, allowing us to create the perfect bespoke fasteners and precision machined components, every time.

We will discuss the intended use and application of your new fasteners, as well as any specific performance or design criteria that must be met.

Once your requirements have been established, we proceed to the design phase. This is where our technical team will create detailed drawings of your new fasteners and/or components, all based on your specifications or previous drawings for each part. We’ll also detail the appropriate materials and manufacturing processes that will be used.

Wulfrun precision machined components and bespoke fasteners design process



After your new designs are finalised, we move onto manufacturing your bespoke fasteners and components. We employ a variety of processes to guarantee the best results. This includes: milling, turning, thread rolling, screw cutting, broaching, spark eroding, grinding, laser cutting and forging. 

Once machined, we finish with any necessary heat treatment or surface finishing.
