3M 7100034892 Hookit Disc Pad 5 in X 1 in 5/8-11 Thread

Product Description

The 3M 7100034892 is a Hookit disc pad designed for use with rotary sanders equipped with a 5/8-11 external threaded shank. It measures 5 inches in diameter and 1 inch in thickness, with a 5/8-11 internal thread that locks securely onto compatible rotary tools. This pad serves as an interface between the sander and either Hookit abrasive discs or Finesse-it buffing and polishing pads. It is typically installed and used by automotive refinish technicians, body shop professionals, and industrial finishing tradespeople working on large surface areas requiring uniform material removal or final polish.

This disc pad is suited for large-area buffing and polishing applications across automotive, marine, and industrial finishing environments. It is compatible with 5-1/4 inch buffs and 5 inch Hookit discs, making it a versatile backing platform for both abrasive and polishing operations on flat or gently contoured panels. It is sold individually and is well matched to rotary sanders used in production and detail finishing workflows.

Installation Notes

Installation is performed by threading the pad clockwise onto the rotary sander shank until snug — no power tools are required for attachment. Always power down and unplug or lock out the sander before mounting or removing the disc pad. Confirm the shank thread is 5/8-11 external before installation to avoid cross-threading or damage. Follow applicable workplace safety guidelines when operating rotary power tools.
