Zafety Lug Lock

• Revolutionary new safety product
• Setting new standards in wheel management
• Helps prevent lug nut loosening
• Reduces risk of potential wheel loss
• Decreases the possibility of costly wheel damage

3
Zafety Lug Lock

• Wheel nuts loosen as a result of temperature
  change and wheel vibration.
• Zafety Lug Lock creates resistance between 2
  nuts minimizing their ability to rotate loosen.
• Designed for use on all wheels with 1-5/16 inch
  (33mm) nuts on 3.5 inch stud centers.
• Easily installs over 2 adjacent nuts.

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 provides a clear, visual check
  of lug nut position

The installation of Zafety Lug 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
• 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
• Reduces need for replacement lug nuts and reduces
  expensive wheel damage
• Economical to outfit commercial vehicles
• Reusable on replacement wheels

Zafety Lug Lock temperature and vibration
testing

• Testing performed by Bodycote Testing Group
• Parameters
• 1. Three Zafety Lug Lock units tested
• 2. Temperature testing at 25C (77F) , 50C
  (122F) and - 40C (-40F)
• 3. Vibration test at 30 Hz and 3 g acceleration
  amplitude
• 4. Each segment of the test was two hours with
  a total duration of 6 hours

9
Zafety Lug Lock temperature and vibration
testing

• TEST PROCEDURE
• 4 nuts tightened to spec (450-500 psi)
• 2 nuts hand tightened
• White line applied to nuts and bolts to identify
  positioning
• Vibration at specific temperature for 2 hours
• Visual inspection of Zafety Lug 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 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

12
TEST REPORT Zafety Lug Lock prevented nuts from
loosening in vibration and temperature testing.

• Lug Nut position at 50C (122 F) after
  vibration testing

• Lug Nut position at 50C (122F) before
  vibration testing

No evidence of nut looseness
