8mm crank arm bolts
Basic hardened steel M8 crank bolts with a flanged 14mm head.
Sold in pairs.
Specifications
• fits all square taper cranksets/BBs using 8mm (M8) bolts
• thread length: 15mm
• color: black
Recommended torque
Proper tightening is crucial to prevent the crank from loosening and damaging the crank arm.
The recommended torque spec for square taper crank bolts is generally 35-45 Nm (300–400 in-lbs) for most setups.
Tighten bolts in stages to 35-50 Nm, alternating sides, or until securely seated. Do not over-torque, as this can deform the crank/spindle interface.
Be sure to check the bolt tightness after the first few rides, as the arms will typically settle on the spindle and the bolts will require slight re-tightening.
