Securex® Wheel Nuts
The First Choice for Virtually All Hub, Drum & Wheel
OEMs in the U.S.

With 3 to 5 times more clamping force than conventional ball-seat fasteners, Securex® means longer wheel life, reduced maintenance and greater safety.

The nut body on each Securex® Wheel Fastener is made of through-hardened carbon steel and each free spinning washer is made of through-hardened and tempered chrome-moly steel. This design generates a bearing-type action which allows more of the torque to be transmitted into clamping force. At the same time, this bearing action offers a more precise torque-to-clamp force relationship, allowing the entire fastening system to be used at the optimum end of the load range.
• Name forged into washer assures product integrity
• Heat lot traceability code on every fastener
• PTFE coating reduces friction, enhances corrosion-protection
• Meets SAE J1965 requirement for torque tension

Securelok™ Wheel Nuts

Securelok™ combines the best of two solutions; consistent torque/tension and formed ramps-and-valleys on the nut-washer interface.

Application torque requirements for Securelok™ are in the same range as current wheel fasteners (450 to 500 lbs/ft. of torque). Resulting joint tension values exceed 45,000 pounds clamp force in laboratory testing.

• Installation torque same as current nuts
• Maintains high clamp load values
• Branded for integrity
• Ramped nut/washer interface resists vibration-induced back off

Joint Integrity Assured
The solution involved requiring the nut to increase joint tension in order to reverse, or back off. During application, the fastener “settles” into a valley between two high spots (ramps). To back off, the nut must rise over a high spot. Laboratory testing shows reverse torque values approaching 80 percent of those required during installation.

Fatigue, Salt Spray Testing Complete
M22 size Securelok™ wheel nuts have completed vigorous fatigue and vibration-resistance testing, as well as long-term salt spray exposure. Ask for your copy of the results of our tests for Torque/Tension, vibration analysis and salt spray performance.

Vibration testing of Securelok™ using state of the art technology (Junkers) to yield remarkable results. Unlike traditional fasteners that exhibit a continual loss of clamp force over the entire test period, Securelok™ performs as expected.

After a slight initial adjustment in clamp force (that still delivers exceptional joint tension) Securelok™ clamp force remains virtually unchanged for the remainder of the test period.
