Product Details
✓INSTANT VISUAL INDICATOR: These dual-purpose one wheel accessories quickly indicate and retain against unwanted wheel nut movement, and indicating any overheating of wheels caused by faulty brakes or bearings to prevent the wheel from coming off.
✓SUPPORTS FLEET SAFETY CHECKS: Enable visual checks and monitoring to see in real-time what's going on with all of your wheels with our wheel nut indicator! It keeps track of wheel nut tightness.
✓EASY OPERATION: Install these wheel nut indicators over the wheel bolt. By placing the Checkpoints in a recognizable pattern such as point to point, any movement of the wheel nut is clearly visible at a glance. It melts at 125ºC or 257ºF to highlight overheating issues with the wheel or application.
✓48-TOOTH HIGH PRECISION DESIGN: Featuring 48 contact teeth for enhanced grip, precise positioning, and consistent alignment—delivering greater accuracy than standard indicators with fewer teeth.
✓MULTIPLE FITMENTS: Mainly for commercial vehicles such as trucks, agricultural vehicles, dangerous goods transporters, this visual indicator is also used in the industrial sector, and wherever safety critical fasteners can loosen due to heavy vibrations.
