    Kronos Aluminum 7075-T6 Inner Chainring Screws (set of 5) 15.5 mm length - Purple (3D-Violet) Anodized
    Application: For a MTB triple crankset , these bolts attach the inner chainring to the crank arm. These are 15.5 millimeter long so they would typically require a spacer in between the inner chainring and the crank arm. If you need a different length, I also have these in 8mm (black anodized) and 13 mm (silver anodized). See photo above that shows the dimensions of the bolt. The thread is M8 X .75 and the bolt shank is threaded to about 13.5 mm.
    Kronos Engineering's chainring screws first hit the market in 1988. They were the nicest looking and best quality of all the aluminum bolt kits that followed. Using top quality and strength 7075-T6 Aluminum alloy, these bolts were precision machined on Swiss screw machines, the same machines that are used for Rolex, Tag-Heuer, IWC, and many other Swiss watches, Kronos screws are the highest quality fasteners money can buy. Designed and engineered by an aerospace engineer and bicycle racer who knew where and how to save precious weight on the bicycle. They will never rust and will last a lifetime. Check proper installation torque specs. on the back side of the packaging.
