SP type bushings are similar to P type bushings but with top serrations to prevent rotation in soft materials. SP bushings are recommended in high-torque situations for materials such as, magnesium, aluminum, masonite or wood. A finish ground OD provides an accurate ID location. Serrations also resist axial force to prevent pushing the bushing through the jig plate. Standard sizing and ANSI part numbers for SP and SPM (metric) type bushings are listed in the tables below.
