DESCRIPTIONThis motor mount screw is for bakelite motors only. If the motor has a bakelite motor pulley, it most likely has a bakelite motor housing. Also the bakelite motors have ventilation slots where as the metal ones do not. The screw will either come in black or chrome and will include a washer. We also carry a screwdriver that is perfect for removing this screw. Contact us if you have any questions regarding this product.
