Checkpoint Checklink 33 mm Dark Grey Wheel Nut Indicator & Retainer

Checkpoint Checklink 33 mm Dark Grey Commercial Wheel Nut Indicator & Retainer

The Checkpoint Checklink 33 mm (Catalog Index: CHP-CLDOG33) is a dual-function safety device manufactured by Checkpoint Safety for commercial vehicle transport, freight fleets, buses, and trailers. Designed to fit 33 mm wheel nuts across standard commercial steel and alloy rims, the Checklink links adjacent wheel nuts together in an S-shaped polymer bridge, actively retarding nut loosening while providing immediate visual indication during daily pre-trip vehicle inspections.

Key Performance & Structural Highlights

Active Dual Functionality (Indicator + Retainer): Integrates visual inspection capabilities with mechanical retention, preventing wheel nuts from backing off under heavy road vibrations and braking forces.

Thermal Overheating Early Warning: Formulated from a engineered polymer designed to distort and soften at 125°C (257°F), giving fleet operators an unmistakable visual sign of hub overheating caused by sticking brakes or failing wheel bearings.

Durable & Bio-Friendly Polymer Build: Manufactured from high-grade virgin polymer with a dark grey (military khaki) finish that resists road salts, weathering, and shop chemicals.

Streamlined Fleet Safety Audits: Simplifies daily driver walk-around checks and supports compliance with road safety standards (DVSA, FORS, and ISO fleet safety requirements).

Easy Tool-Free Installation: Clamps quickly over adjacent 33 mm hex nuts without requiring specialized fitting tools.
