Safety Nuts to Match Your Specifications


Improve Your Assembly with Metric Security Nuts

Metric triangle nuts offer many advantages to metric assemblies across markets and industries. Constructed from high-quality Class 5 steel and featuring a zinc-plated finish, our security nuts provide long-lasting and reliable performances. Other benefits include:
  • Increased security from the tamper-proof nut design
  • Limits access to protect assemblies
  • Final products with improved durability
  • And more!

How to Install & Remove Safety Nuts

Installing and removing security nuts is accomplished using a specialty triangle socket wrench that matches the size of your safety nut. To install the triangle nut, simply place it onto any metric bolt with a matching thread. Removing security nuts is a slightly more complicated process due to the tamper-proof characteristics and design of the nut. Place the specialty socket wrench over the nut, turn, and unlock the component.
