ZERO NUTZ are a super lightweight alternative to traditional metal axle nuts with an added bonus. ZERO NUTZ are designed with a unique one of a kind bearing guard that protects you bearings from skate tools, socket wrenches, or anything else that might dent or damage your bearing shields. Because they are made out of nylon they won't come loose on their own accord. This unique concept is the first of its kind in roller skating, never damage your bearings again. Individually packaged in sets of 8 and suitable for standard 8mm axles.
