Automann 201.LWI33 Loose Wheel Nut Indicator 33mm Yellow 10-Pack

The Automann 201.LWI33 Loose Wheel Nut Indicator provides a simple, visual safety solution for monitoring lug nut tightness on heavy-duty commercial vehicles. This 10-pack of yellow polyurethane indicators fits 33mm wheel nuts and helps prevent dangerous wheel-off incidents by allowing quick visual inspection of wheel nut movement.

Key Features:

• Fits 33mm lug nuts commonly found on commercial trucks and trailers
• High-visibility yellow color for easy inspection
• Flexible polyurethane construction designed to stay securely attached
• Distorts and melts at 230°F to indicate excessive wheel temperature
• Provides early warning of loose wheel nuts, overheating bearings, or brake issues
• Installed in a point-to-point pattern for clear visualization of any movement
• Helps meet fleet safety inspection requirements

When installed in a uniform pattern around the wheel, any wheel nut movement becomes immediately visible, allowing maintenance personnel to identify and address loose fasteners before they become a safety hazard. The temperature-sensitive material also serves as an early warning system for wheel bearing or brake problems that cause excessive heat buildup.
