Theft-Proof Lock Nuts

The Locknut Guard is an all-tensile carbon steel, completely reusable, high-quality lock nut with an independent locking pattern. Our expert engineers uniquely design each locking wheel nut set for each client and manufacture a specially encoded socket key fitted to its own locking system. This coding pattern information is protected and never shared beyond our designers who can issue you a replacement.

Carbon steel is known for its extremely high strength, hardness, ductility, and resistance to wear - so, essentially, the only way your lock nut will ever loosen is through your key. Our lock nut sets are designed individually, so no matter the type or size of truck and trailer wheels you have, we can keep them secure.

Constant Protection for Clear and Productive Minds

Knowing your truck and trailer wheels are always secure provides freedom to park and store your vehicle more conveniently, reach previously compromising locations, and even expand your capacity. With clarity and productivity, your teams can perform better with one less thing to worry about.

Custom Solutions

Our products are uniquely designed with encoded wheel lock nut socket keys that only match your set. As we’re the designers and manufacturers, we can create custom lock nut sets for your specific wheels and build a set for your entire fleet.
