Bicycle Crank Arm Bolts

Maintain the integrity of your propulsion system with our Bicycle Crank Arm Bolts collection. We provide a wide range of precision-engineered fasteners designed for every crank standard, from self-extracting caps for modern SRAM and Shimano systems to hardened steel bolts for square-taper and ISIS spindles. Our collection includes high-strength 7075 aluminum and stainless steel options, often featuring pre-applied threadlocker or integrated washers to prevent backing out under vibration. Whether you are replacing a rounded-out bolt on your MTB rig or upgrading to lightweight anodized hardware for a custom road build, our bolts deliver the consistent torque and durability needed for a creak-free, reliable connection.
