20-Piece Set Black ABS Wheel Hub Nut Protective Caps (17mm, 19mm, 21mm)

Shield exposed lug bolts and maintain consistent wheel aesthetics with this bulk pack of 20 protective covers. Engineered from high-density ABS plastic, these caps seal the thread area against road salt, moisture, and airborne debris that lead to rust and seized hardware.

This mixed-size kit resolves compatibility issues across different vehicles by providing 17mm, 19mm, and 21mm options in a single shipment. The matte black finish coordinates seamlessly with standard alloy rims and wheel centers. Installation is immediate—push the synthetic polymer cap over the hexagonal bolt head until fully seated.

Durability is the primary advantage over metal alternatives. The synthetic resin composition withstands extreme weather cycling without becoming brittle or cracking under pressure. By covering the nut head, you prevent accumulated grime from clogging the threads during disassembly, ensuring tires remain serviceable for every rotation.
