Low-profile industrial locknut similar to THU, but with a much lower height. Excellent option when designing bolted joints that require precisely controlled heights in confined spaces.

Dual-slotted, all-metal, self-locking hex nut. It’s has impressive characteristics: extremely reliable, consistent prevailing torque, and no galling. The dual-locking slots function independently of bolt tension. The ESL is a true single piece all metal design.

Full-height, heavy hex industrial version of our ESL nut. Locking slots are concentrated on a single plane. Superior resistance to vibration, corrosion, and temperature in a robust industrial design.

The one-piece ERM is a great time saver with its integrated disc spring washer. The result: quick installations and absolute tension maintained under dynamic loads. Ideal for imperfect bearing surfaces and electrical contacts.

A reusable one-piece locking jam nut that’s able to withstand high temperatures. Great on terminal posts and electrical panels.
