Package of 20 loose wheel nut indicators for 7/8" (22.0mm) nuts. The Wheel-Check provides a simple, visual means of confirming proper wheel nut torque in seconds. Reduces risk of wheel detachment accidents and resulting load damage and may reduce insurance costs. Reduces equipment downtime and maintenance costs associated with needless re-torquing. Provides a visual commitment to safety to the public and to transportation authorities. Drivers, mechanics or inspectors can confirm proper wheel torque or identify bearing or brake overheating problems at a glance. Costs only a few dollars per wheel and pays for itself if just one re-torque is avoided.

• Temperature-sensitive polymer detects bearing or brake overheating problems by deforming at temperatures above 120°C / 250°F
• Will withstand extreme cold temperatures (-75°C / -100°F) without cracking
• Resistant to highway and cleaning chemicals
• Easy to install and difficult to tamper with or dislodge
• Bright yellow Wheel-Checks are visible at night and in dirty or muddy conditions
• Red Wheel-Torque used to replace the Wheel-Check which indicates nut loosening to identify nut which needs re-torquing
• Wheel-Checks are applied pointing in a uniform clockwise direction after ensuring proper wheel torque (apply with “lip” toward wheel)
• A Wheel-Check will rotate counter-clockwise if wheel nut loses torque
• Reduces costly wheel stud wear and breakage due to continuous re-torquing (stud manufacturers recommend stud replacement after 3 torques)
