SP

FEATURES: Similar to a P bush, but with top serrations to prevent rotation in soft materials. SP bushes are recommended in high-torque situations for materials such as magnesium, aluminium, masonite, or wood. Finish-ground OD ensures accurate ID location. Serrations also resist axial force to prevent pushing the bush through the jig plate.
