Stainless Steel sprocket nut set. Manufactured from high grade material, these highly polished nuts will not fade or corrode due to the excellent material properties of 316 Stainless Steel and machined with rolled threads to give a smoother, stronger finish the perfect way to brighten up your rear end!
Can be torqued to manufacturers’ original settings. Listed in model specific bike sections where fitment has been established.
Compliments rear axle nuts and chain tension adjusters perfectly. Please use our vehicle search for model specific fitments.
Prefer something a little more subtle? This kit is also available in Black Stainless Steel which not only looks great but has other benefits too..
This beautiful long lasting black finish results from an application of Diamond Like Carbon Coating (DLC) This gives supreme hardness and corrosion resistance provided by a nano composite coating, which increases the fastener lifetime dramatically and helps to prevent galling. By incorporating them right from the beginning, the overall system cost can be held level or may even be reduced.
Please note that due to this special coating Black Stainless Steel is not identical to our Black Aluminium.

    The best product on the market

    When you compare Pro-Bolt hardware to other manufacturers products it is clear Pro-Bolt is superior. The Coating I believe is the best in the industry and can not be beat. The Gold looks the best on stainless !!!
