3M 7010363954 Hookit Disc Pad 8 Inch Firm

Product Description

The 3M 7010363954 is a Hookit disc pad designed to back 8-inch Hookit abrasive discs during surface preparation and finishing operations. The pad measures 8 inches in diameter with a 5/16-inch face thickness and a 7/8-inch overall body depth. It threads onto standard 5/8-11 spindle threads and holds a firm grade backing, which provides stable support for consistent stock removal and controlled sanding pressure. Licensed tradespeople and finishing technicians use this pad as the mechanical interface between a rotary or random-orbital tool and the abrasive disc, making proper pad selection critical to disc retention and surface quality.

This disc pad is suited for surface prep tasks in automotive body work, industrial fabrication, and general metalworking or composite finishing environments. The Hookit attachment system uses a hook-and-loop retention method, allowing fast disc changes without tools. Firm-grade pads are typically selected when a flat, stable backing surface is needed and when the workpiece geometry does not require a conformable or soft-grade pad. It is sold as a single unit per case.

Compatibility

Designed for use with 8-inch diameter Hookit abrasive discs on tools equipped with a 5/8-11 threaded spindle.

Installation Notes

Installation is performed by tradespeople and finishing technicians familiar with rotary and random-orbital sanding equipment. Before mounting or removing the pad, disconnect the tool from its power source or air supply. Thread the pad fully onto the 5/8-11 spindle by hand and verify it is seated securely before attaching an abrasive disc. Inspect the hook-and-loop surface for wear or contamination before each use, as a degraded retention surface can allow the disc to detach during operation.
