Our high-skilled engineers have developed and qualified a range of fasteners and self-locking nuts for Aerospace applications, offering a complete design, test and approval service for customers. These self-locking nuts were developed and qualified by our engineers using a finite element model supported by empirical data.

We offer our own SigmaLite range of aircraft parts, home to new versions of the self-locking nuts, along with concept designs for a range of lightweight metallic end fittings, redesigned and manufactured using both traditional and additive manufacturing techniques.
