3M 7010309134 Flap Disc Adapter Nut 5/8-11

Product Description

The 3M 7010309134 is a flap disc adapter nut designed for use with 3M abrasive flap discs. It features a 5/8-11 internal thread pattern, which is the standard thread specification for angle grinders commonly used in metal fabrication, welding prep, and surface conditioning work. The adapter nut secures the flap disc to the grinder spindle, providing a stable mounting interface during aggressive stock removal or finishing passes. Sold as a pair, it is a direct replacement or supplemental hardware item for shops and field crews running 3M abrasive flap disc systems. Fabricators, welders, and metalworkers are the primary installers.

This adapter nut is suited for use in industrial and commercial fabrication environments where 3M abrasive flap discs are part of the standard tooling lineup. It is applicable on angle grinders equipped with a 5/8-11 spindle thread. Common use cases include weld seam blending, surface preparation before coating, and deburring on steel, stainless, and aluminum workpieces. The unit of measure is a pair, making it practical to keep spares on hand for high-volume grinding operations.
