This indicator is suitable for rims with fully exposed wheel nuts, as well as alloy & chrome rims with recessed nuts, with a depth of up to 38mm / 40mm / 45mm.

While acting as a visual indicator to loose & missing wheel nuts, and excessive heat, the cap design also protects nuts from mud, dust, dirt and damage.
