Axle Pin - Drive Pin - HEX PIN --

A small metal pin that is inserted into a hole in a drive axle just outside of the hub carrier. This holds the axle in the hub and provides a mounting key for the rims. Depending on the model, the rim may be keyed directly to the axle pin, or a wheel hex may be keyed to the pin with the rim keyed to the hex. Either way, the pin allows the rim to be secured to the axle and rotate with it. Keep an eye on your axle pins, they tend to wander off once your rims are removed.
