DuraBlue now has the famous Posi*Lock style axle retaining nuts available for non-DuraBlue as well as DuraBlue axles. These nuts have fewer parts than the OEM nut assemblies and are less sensitive to vibration and harmonics (the physical motions responsible for loosening). They are an excellent addition to any well maintained machine. Please note that unless specified below as "steel", the clamping nut will be aluminum.
