Is there a bolt with a 15mm head I can use instead of the stupid alan key bolts for my female hub axle?
What thread size? The answer is still probably no, since 15mm AF isn't a normal nut or bolt head size. What are you finding particularly stupid about Allen key screws? If it's the inability to apply enough torque without damaging either the socket or the driver, Torx is the answer. If it's a rear hub, chain tugs are the answer, I have no trouble with my M6 hub retaining screws, because the chain tugs handle the chain tension so I only need to apply 6-8Nm to the screws to hold the wheel in the bike.
