Sugino crank arm bolts & washers
For those who prefer keeping it real when it comes to their Sugino crank arms, this is the same genuine Sugino hardware supplied with Sugino 75 & Super Lap bottom brackets, and are perfectly paired with Sugino CNS Dust Caps (sold separately).
Of course, they'll work with any other square taper crank arm/BB combo that uses a standard M8 bolt too, not just Sugino.
ⓘ We recommend putting a drop of blue thread locker on the threads before installing to keep them from backing out and needing regular adjustment.
Specifications
• hardened steel w/ 14mm head
• fits all cranksets/BBs using 8mm (M8) bolts
• sold in pairs
• 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.
