Introducing Zafety Lug Lock Wheel Nut Security System

Introducing…. Zafety Lug Lock® Wheel Nut Security System

Zafety Lug Lock® Design engineered for superior wheel nut security. Pairs together two lug nuts and ensures that resistance is applied continuously to the lug nuts to secure them from loosening. Reduces risk of potential wheel loss. Decreases the possibility of costly wheel damage.

Zafety Lug Lock® Wheel nuts loosen as a result of temperature change, vibration and wheel surface condition. Loose wheel nuts result in an unbalanced load on a wheel end Unbalanced wheel load stresses studs and nuts and can lead to nut loosening, stud shearing and wheel damage

Zafety Lug Lock® Lock can reduce the risk of dangerous and costly wheel separation from loose lug nuts! Wheel fasteners are the single largest cause of wheel separation (66%) issues.

Zafety Lug Lock® Zafety Lug Lock® nuts Lock is designed to ensure wheel w remain secure prior to scheduled retorquing. Zafety Lug Lock® Lock creates resistance between 2 nuts minimizing their ability to rotate & loosen. Easily installs over 2 adjacent nuts. Use on standard or hub piloted 10 stud wheels with 15/16 inch (33 mm) nuts on 3 -1/2 inch centers and 4 -1/8 inch centers. Also designed for 8 stud wheels with 7/8 inch (22 mm) and 1. 0 inch (25 mm) nuts on 2 -1/2 inch centers.

Zafety Lug Lock® Pre-trip inspection requires confirmation of secure wheel lug nuts Rules apply to all public transit & commercial buses, trucks, trailers Zafety Lug Lock® Lock provides a clear, visual check of lug nut position* * The installation of Zafety Lug Lock® Lock does not preclude the need for standard safety & maintenance procedures

Zafety Lug Lock® Fleet and Driver liability is a critical issue: NHTSA records show 1, 000 reported accidents resulting from wheel loss in 2008. Many wheel loss incidents go unreported. $6. 25 million civil award in a California personal injury accident from a wheel off

Zafety Lug Lock® Benefits Nut can be checked for proper torque with Zafety Lug Lock® installed (Exova Report # 10 -03 -0152 Rev 1, June 2010) Provides a clear visual check of lug nut security Reduces risk of wheel loss and potential liability for personal injury, loss of life or property damage Retains loose nut if stud breaks or shears off Reduces need for replacement lug nuts and reduces expensive wheel damage Reusable on replacement wheels

Zafety Lug Lock® Features Design engineered plastic components with patented product design. Flexible and easy to install or remove for wheel end service - fits over two adjacent nuts. High temperature formulation for severe braking with wheel end brake temperatures up to 4500 F (2320 C). Resistant to continuous chemical exposure typically found in automotive and transportation applications. Available in custom colors

Zafety Lug Lock® Features Zafety Lug Lock® Lock has a high strength to weight ratio 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). Field and track tested at high and low rotation levels over severe road conditions

Zafety Lug Lock® temperature and vibration testing Testing performed by Bodycote Testing Group (Exova) (Report # 08 -03 -C 0185, July 2008) Parameters: 1. Temperature testing at 25⁰C (77⁰F) , 50⁰C (122⁰F) and - 40⁰C (-40⁰F) 2. Vibration test at 30 Hz and 3 g acceleration amplitude Test Procedure: 4 nuts tightened to spec (450 -500 ft-lbs) 2 nuts hand tightened Visual inspection of Zafety Lug Lock® Lock units and nuts for any changes

TEST REPORT: Zafety Lug Lock® prevented nuts from loosening in vibration and temperature testing Observations After testing at each temperature level a visual inspection indicated the Zafety Lug Lock® Lock units did not sustain any external damages or physical degradation After testing at each temperature level a visual inspection indicated no evidence of any nut looseness

Zafety Lug Lock® Lock will have a positive impact on fleet maintenance and safety: Reduced liability from risk of potential wheel loss. Lower maintenance costs from possible wheel damage and lug nut replacement. Nut Torque Check without removal saves time. Simple visual check on wheel nut position Allows fleets to visibly demonstrate proactive safety measures
