3M 7000045692 Roloc Disc Backup Pad 75mm M14-2.0

Product Description

The 3M 7000045692 is an extra-hard backup pad designed to support Roloc 3-inch (75 mm) diameter abrasive discs. It mounts directly to angle grinders and rotary tools with M14-2.0 external threaded shafts via its M14-2.0 internal thread interface. The extra-hard pad density provides firm, consistent backing pressure across the disc face, which is suited to aggressive material removal and surface prep tasks. An 11/16-inch hex nut design simplifies installation and removal during disc changes on the job. Sold individually.

This backup pad is used in metal fabrication, automotive bodywork, weld prep, and general surface conditioning applications. It is compatible with air-powered and electric rotary tools that accept M14-2.0 threaded shafts, which are common on angle grinders used in industrial and body shop environments. The 75 mm working diameter suits standard 3-inch Roloc disc inventory.

Installation Notes

Installation is performed by machinists, fabricators, and body shop technicians using standard hand tools. Disconnect or power off the tool completely before mounting or removing the backup pad. Thread the pad onto the M14-2.0 shaft by hand first, then use an 11/16-inch wrench on the hex nut to secure. Inspect the pad for wear or cracking before each use and replace if the surface shows deformation that could affect disc seating.
