Cold-formed fasteners
Cold-formed fasteners are high-strength components that are produced by shaping metals at room temperature using high-pressure dies.
This process, coupled with post-heat treatment, improves the structural, tensile and fatigue strength of metal fasteners, enabling them to perform in demanding, high-stress environments.
Engineered in-house. Reliable worldwide.
The LoneStar Group is a world-leading manufacturer and supplier of cold-formed and special fasteners, producing a broad scope of high-performance, approved and accredited bolts, screws, rivets, pins and socket products. By forming these components through cold forming, we retain traceability and quality of the product at all times.
Our cold-formed fasteners are manufactured in-house to ensure our teams – and our customers – have complete control over the production schedule with zero reliance on third parties. All components are manufactured from European raw materials to ensure quality and traceability at every stage.
Thanks to the longstanding expertise of our skilled technicians, we are also able to manufacture cold-formed fasteners to customer requirements and specifications that include, but are not limited to:
