Buying Guide

Match thread pitch and size

Confirm your hub and wheel use M14x1.25 or M14x1.5 threads — mismatched pitch will prevent proper installation and can cause failure

Check shank/extension length

Wheel spacers require extended shanks (e.g., 40–45mm) so bolts fully engage the hub after spacer thickness is added

Choose the correct seat type

Use conical (cone) or ball seats to match your wheel’s seating surface; incorrect seats can produce uneven clamping or wheel damage

Hex size and tool compatibility

Confirm the bolt head hex (commonly 17mm) fits your lug wrench or torque socket to ensure proper torque and avoid rounding

Prioritize material and construction

Select bolts made from hardened steel with consistent plating to resist corrosion and maintain clamp load when used with spacers
