The Profile Hex Head Axle Bolt is a 3/8"x16tpi chromoly axle bolt with 17mm hex head, 8mm Allen key socket and extra long 14mm shoulder for peg use. Designed for those who run Profile hubs with 3/8" axle bolts in a 14mm dropout frame.
Note: When installing the bolt, make sure the shoulder of the bolt does not protrude past the inside of the dropout. If it does, you might need to add additional washers. Failure to install this bolt properly will result in damage to your hub.
