Site Facilities

Shop Floor

2508m2 We are the Manufacturer and as such are in control of all processes, European Raw Materials All materials on site are from European Source and additionally chemically validated once on site and ‘each bar’ in hard etched to confirm traceability. Hot Forging We offer Hot Head Forging process and can offer bolting in a range of head forms such as, Hexagon, Socket Head, Bi Hex (12 point), or any additional ‘bespoke’ head form. Heat Treatment We offer Heat Treatment to Carbon Steels and Exotic materials, we can perform limited scope in house and also have approved sub suppliers that are fully approved and accredited to customer and Industry Standards. Mechanical Testing (Destructive and Non Destructive) We have our own Internal Testing Laboratory that is BSEN 17025 Approved. We can offer a range of testing processes and invite you to view the website for further information. Capability can be confirmed on request. NDT Testing We have approved processes on site for both MPI and DPI to both PCN and ASNT requirements. CNC Machining We have a range of machine capabilities for threaded and non-threaded components, we have sliding head machines that are capable of high repetition and enable us to machine large volume or small batch components in line with our customer requirements. Again we are happy to provide capacity ranges on request. Plating We have our own in house plating facility that can offer a range of PTFE and Phosphate coatings. All our paints are Whitford Approved and the facility is approved to Industry and ‘bespoke’ customer requirements. We can provide procedures in line with customer internal processes as and when required. If you do have any High Criticality Fastener or General Machined Components (Non-Threaded) requirements in coming weeks or would like to discuss any ongoing Technical requirements, then please do not hesitate to call us and we will be happy to assist.
