Security Locknuts are a reliable and robust solution for ensuring the integrity of bolted joints in a variety of critical applications. Designed as an all-steel, fully reusable prevailing torque locknut, this innovative fastener plays a crucial role in enhancing the safety and stability of diverse industrial equipment and infrastructure.
THE ORIGINAL SECURITY LOCKNUT
FOR OVER 100 YEARS
At its core, the Security Locknut is a one-piece assembly, seamlessly combining a spring steel insert lock ring with a sturdy steel nut body. This construction imparts exceptional strength and durability to the locknut, making it well-suited for applications where the reliability of bolted connections is paramount.
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).
