21mm orange Wheel Nut Locker 4-pack loose. Specially designed for 5x21mm wheel nuts on wheels with trims and step rings.
Easy to install, our Wheel Nut Locker is both a loose nut indicator and a nut retainer. Installed as a single piece over all five nuts creates resistance between the nuts to minimise their ability to rotate and prevent them from loosening. The Wheel Nut Locker is designed with a long-reach (54mm) barrel, specially designed for wheels with trims and step rings.
Our Wheel Nut Lockers are manufactured to the highest quality, using impact copolymer polyethylene, which provides stiffness and impact resistance properties.
