Stock Material + In-House Engineering

Victory Fasteners maintains raw material and fastener blank stock specifically to provide greater flexibility across non-standard and bespoke requirements.

For this component, manufacture from EN19T round bar provided a direct route to the required M20 × 640 specification, with the principal machining operations completed in-house.

This combination of stock availability and machining capability enables Victory to respond to requirements involving non-standard lengths, diameters, head forms and component configurations without relying solely on the availability of finished standard fasteners.

A Controlled Supply Route

From raw material through machining, identification and inspection, the component was managed through a single supply route at Victory Fasteners.

Based centrally in the West Midlands, our manufacturing facility also provides a practical logistics base for supporting engineering and manufacturing customers throughout the UK.

For bespoke fastener requirements, the objective is straightforward: the correct material, the required specification and an efficient manufacturing route to finished component.
