3M 7100001985 Hookit Disc Pad 3in 5/16-24 External

Product Description

The 3M 7100001985 is a Hookit disc pad designed to back and support abrasive discs and buffing pads during sanding and finishing operations. Measuring 3 inches in diameter and 0.5 inches in thickness, this pad features a 5/16-24 external thread for secure attachment to compatible orbital sanding tools. It provides a firm, consistent backing surface that helps maintain disc contact across the workpiece. Installers and finishing technicians rely on this type of pad to ensure even abrasion, reduce disc slippage, and extend disc service life during surface prep and finishing work.

This disc pad is suited for surface preparation, paint finishing, and polishing applications in automotive body shops, manufacturing, and industrial maintenance environments. It accepts 3 inch diameter Hookit discs or 3 inch through 3.75 inch Finesse-it buffing pads, making it compatible with a range of 3M finishing consumables. It is intended for use with random orbital sanders and other power tools equipped with a 5/16-24 internal thread spindle.

Installation Notes

Thread the pad onto the tool spindle by hand, ensuring full thread engagement before operating the tool.
