3M™ Disc Retainer Nut securely fastens a fibre disc to a disc pad hub or face plate for use with a rotary power tool. This nut is made to fit 3M™ Disc Hubs and 3M™ Face Plates, but also fits fibre disc holders from other manufacturers.
After placing the disc pad hub, disc pad face plate, and fibre disc onto the tool, the final step to secure these items is to tighten the 3M™ Disc Retainer Nut.
