Sure-Grip ZERO NUTZ are produced in the USA using a revolutionary nylon material. ZERO NUTZ are a super lightweight alternative to traditional aluminum axle nuts with an added bonus. ZERO NUTZ are designed with a unique one of a kind bearing guard that protects your bearings from skate tools, socket wrenches, or anything else that might dent or damage your bearing shields. This same bearing guard also protects against dirt and debris from entering the bearing whether you skate outdoors or indoors. This unique concept is the first of its kind in roller skating, never damage your bearings again.
