Our crank bolts are machined out of US produced stainless steel and are 20 mm long. This allows for more than 3/4 inch of engagement with the spindle. To maximize the strength of these bolts, the threads are first cold-forged then the bolts are subjected to two heat-treat processes to maximize their strength. The head of the bolt accepts an 8 mm hex head wrench.
Please Note: The crank bolt quantity is for individual bolts, not sets. You will need to order a quantity of 2 in order to have a set of bolts.
