Aerospace fastener screw specifications

As part of our commitment to providing to continually improving our customer experience, we have made our most popular part specifications available on our website.

We hope that you will find the charts helpful, but remember that we are always here to assist with any inquiries so please don’t hesitate to pick up the phone and speak to a member of the team on +44 (0)208 504 8833

What makes us unique in the UK Aerospace Fasteners industry is the fact that we not only carry an incredible 35,000 different lines of stock, but that we are one of the only firms to make and manufacture our core product offerings.

This means that we can supply rare and unusual screw specifications of all varieties. It places us in an ideal position to assist with some of the most challenging and cutting-edge engineering projects in areas such as space exploration, commercial aviation, defence, nuclear, rail, oil & gas, petrochemical, medical and data-security.

We also have an in-house custom design team capable of delivering small or large scale production, along with the ability to source and replicate rare and vintage fasteners for classic aircraft and plant.
