Merit Abrasives 08834195000 Retaining Nut 5/8-11 Female

Product Description

The MERIT ABRASIVES 08834195000 is a female retaining nut designed to secure sanding discs onto air-cooled rubber back-up pads in quick-change disc systems. Manufactured from steel, this retaining nut features a 5/8-11 thread size and measures 0.625 inches in length. It is a direct hardware component used in abrasive finishing setups where quick-change resin fiber sanding discs are mounted to back-up pads. The steel construction provides the thread engagement strength needed for repeated disc changes in production grinding, blending, and surface preparation work. Licensed abrasive equipment technicians and surface finishing professionals typically source this part as a replacement when retaining hardware shows wear or damage.

This retaining nut is intended for use with air-cooled rubber back-up pads and quick-change resin fiber sanding disc systems. It is suited for both shop and field applications where 5/8-11 threaded spindles are standard, including angle grinder and disc sander setups common in metal fabrication, weld blending, and floor or surface finishing environments. The female thread configuration mates to a male spindle arbor on the back-up pad assembly.

Compatibility

Designed for use with air-cooled rubber back-up pads and quick-change resin fiber sanding discs requiring a 5/8-11 female retaining nut.

Installation Notes

Installation should be performed by a qualified technician familiar with abrasive disc hardware. Always disconnect or power down the tool before replacing retaining hardware. Thread the nut onto the spindle arbor by hand first to confirm proper thread engagement before applying a wrench, and do not overtighten, as this can damage the back-up pad hub or spindle threads. Inspect threads on both the nut and spindle for wear before reinstalling.
