3M 7010326135 Spindle 5/16-24 Thread Random Orbital Sander

Product Description

The 3M 7010326135 is a steel spindle designed for use with 3 inch random orbital sanders. The backup pad threads directly onto the spindle via a 5/16-24 internal thread, making it a core mechanical component in the sander assembly. This spindle is the interface point between the sander tool body and the backup pad, and its precise thread spec ensures a secure, vibration-resistant connection during operation. HVAC, auto body, and general fabrication technicians who service or rebuild orbital sanding equipment will find this a straightforward OEM-style replacement part.

This spindle is intended for use on 3 inch random orbital sanders with a 3/16 inch orbit. It is suited for light industrial and professional finishing applications where the original spindle has worn threads or has been damaged. Installation requires only basic hand tools and is performed when replacing or servicing the backup pad mounting interface on the sander. Each unit is sold individually.

Key Features

• 5/16-24 internal thread for secure backup pad attachment
• Steel construction for durability under repeated use and torque loads

Installation Notes

Installation should be performed by a qualified technician familiar with power tool servicing. Disconnect and de-energize the tool completely before removing or installing the spindle. Use appropriately sized hand tools to seat the spindle properly; do not overtighten the backup pad onto the spindle threads.
