We designed these bolts to be the best on the market. These single chainring optimized bolts have a 4 mm hex socket on the bolt and a 6 mm hex socket on the nut so no spanner is needed. These are 6 mm long so they work perfectly with any bolt on single chainring that does not have threaded standoffs.
