Spiralock is a technologically superior fastening system ideally suited for threaded joint applications subjected to heavy shock and vibration, extreme temperatures, long hours of strenuous operation, and millions of loading cycles without the opportunity for retightening. Our proprietary internal thread form features a unique 30° wedge ramp at the root of the thread that locks the bolt securely in the threaded joint, offering the following benefits:

• Superior resistance to vibration loosening
• Consistent, repeated reusability
• Radial load distribution
• Improved joint integrity
• Elimination of secondary locking devices

Spiralock products include flange nuts, self-clinching nuts, tanged and Drive Notch™ (tang-free) wire thread inserts, threaded inserts, taps and gages, threading inserts, and thread milling cutters as well as a variety of custom-made products that meet our customers’ needs.

Spiralock products solve fastening issues in a wide variety of applications, including medical implants, surgical instrumentation, avionics and electronics, various aerospace components, exhaust and turbo mounts for internal combustion engines, truck frame and chassis connections, energy generation equipment assemblies, and many other threaded joint applications in a broad range of industries.
