Sunlite 8mm Allen Axle Bolt SetThis 8mm Allen flanged axle bolt set is composed of the two crank bolts that keep the crank arms affixed to the bottom bracket spindle. Very convenient for when you purchase a bike and the assembler didn’t tighten them properly… and then the vibration of riding happens… and you no longer have bolts holding your crank on. This is the cleanest/most beautiful bolt to attach your crank. Requires an 8mm Allen wrench to tighten.072774229161
