Profile Racing Buttonhead Hub Bolts
Buttonhead Bolts replace standard Profile 3/8 (10mm) with a smooth, clean, rounded bolt head.
• A straight 3/8 (10mm) bolt, which will fit 3/8 drop-outs.
• The standard 3/8 (10mm) to 14mm dropouts version.
• The peg version, which has a longer 14mm section that's long enough for both a 14mm peg as well as a 14mm dropout.
• Price is for a pair (2) bolts."
