Save Time and Money With Zafety Lug Lock®

The independent laboratory tested Zafety Lug Lock® helps prevent potential wheel loss by using the resistance between two nuts to minimize their ability to rotate and loosen, a safety product the transportation industry has needed for a long time:

  • Pre-trip inspection requires secure wheel lug nut confirmation
  • Rules apply to all public transit & commercial buses, trucks, trailers
  • Provides a clear, visual check of lug nut position 

Innovative Function

Most wheel nut safety products allow the lug nut to loosen first and only then alert drivers to dangerous conditions. Zafety Lug Lock® uses a proprietary design that lessens the ability of two adjacent lug nuts to rotate and become loose. This reduces the risk of potential wheel loss and the possibility of expensive wheel damage.

 
WHEEL NUTS LOOSEN AS A RESULT OF TEMPERATURE CHANGE, WHEEL END VIBRATION AND SURFACE CORROSION/SURFACE BLISTERING.

Zafety Lug Lock® is fabricated from design engineered plastic that has been independently tested under varying temperature and vibration conditions with no evidence of lug nut loosening and with no external damage or physical degradation.

Zafety Lug Lock® is available in MULTIPLE SIZES for equipping the numerous applications found in heavy duty transportationas well as transit, motorcoach and smaller delivery van vehicles.

Zafety Lug Lock® comes in a High Temperature Formulation designed for severe stop and go braking with a temperature range up to 450⁰F (232⁰C).

 

Design Engineered Plastic Composition

The raw materials that are used in the manufacture of Zafety Lug Lock® have a long history of engineering applications involving extreme environments, both in temperature ranges, and in chemical exposures.

These materials are blended in a proprietary ratio to complete the Zafety Lug Lock® design engineered plastic composition. The resulting product is chemically inert and resistant to intermittent and continuous exposure to the range of chemicals typically found in automotive and transportation applications, including the following:

  • Road salt  
  • Liquid calcium chloride  
  • Hydraulic fluid
  • Gasoline  
  • Transmission fluid  
  • Windshield washer alcohols
  • Iron oxides  
  • Radiator fluid   
  • Locktite
  • Diesel fuel  
  • Ethanol alcohol

Most importantly it has a high strength to weight ratio, and the design has been proven in independent vibration testing to retain lug nuts from rotation in operating temperatures ranging from -40⁰F (-40⁰C ) to +122⁰F (+50⁰C).

Zafety Lug Lock® is functional for severe stop and go braking with wheel end temperatures up to 450⁰F (232⁰C).
