3M 7010328336 Disc Pad Hub 4.5 in 5/8-11 Internal Thread

Product Description

The 3M 7010328336 is a disc pad hub designed to mount abrasive face pads to angle grinders and disc sanders. The hub features a 5/8-11 internal thread metal insert that threads directly onto standard grinder spindles. At 4.5 inches in diameter and weighing 0.28 pounds, this hub provides a stable mounting platform for face plate assemblies used in grinding, surface preparation, and finishing applications. It is installed by HVAC fabricators, metalworkers, and trade contractors who require consistent pad-to-spindle attachment during abrasive work.

This disc pad hub is suited for use with 7-inch and larger face plates on most standard disc pad assemblies. It is appropriate for both shop and field applications where a reliable, threaded hub mount is needed for surface grinding or blending work on metal, concrete, or composite surfaces. The 5/8-11 thread is the most common spindle standard on angle grinders used in trade environments.
