We designed these bolts to be the best on the market. They have a 4 mm hex socket and are 10 mm long so you can use a bash ring with your chainring that has threaded standoffs like our 104 BCD 30t ring, elliptical 104 BCD rings, 76 BCD rings and others. No nuts are included with these bolts as they are intended for use with threaded chainrings.
