The Security Locknut

The Security Locknut is an all-steel, fully reusable, prevailing torque locknut. It is a one-piece assembly of a spring steel insert lock ring and robust steel nut body.

These industrial-strength fasteners are used to secure bolted joints on critical applications on railroad tracks, rolling stock, locomotives, mining chains, vibratory equipment, mining equipment, material handling equipment, crushing & pulverizing equipment, cutting blades, tunneling machines, roller coasters, and much more.

The oval-shaped lock ring resists vibration by clamping perpendicularly about the bolt axis (more on this at our blog: https://www.securitylocknut.com/blog/).
