With a 2.5-inch diameter and a 5\/8-11 internal thread, this hub provides a secure mechanical connection between an angle grinder spindle and a backup plate. It is compatible with the 3M Fibre Disc GL attachment system, formerly sold under the Grit-Lok attachment system name. The hub weighs 0.33 pounds and is sold individually. Fabricators, metal finishers, and grinding technicians working in industrial or shop environments are the primary installers of this component.\u003c\/p\u003e\n\u003cp\u003eThis hub is intended for use with 4.5-inch to 7-inch face plates, making it a versatile fit across a range of disc sizes commonly used in weld blending, surface prep, and stock removal applications. Adapters are available separately for M10-1.25, M10-1.50, and 3\/8-24 spindle shafts, extending compatibility to grinders with metric or finer-thread arbors. It is sold as a single unit and is typically used in professional fabrication, metalworking, and maintenance grinding setups.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e5\/8-11 internal thread fits standard angle grinder spindles\u003c\/li\u003e\n  \u003cli\u003e2.5-inch hub diameter supports face plates from 4.5 to 7 inches\u003c\/li\u003e\n  \u003cli\u003eDesigned for use with 3M Fibre Disc GL (formerly Grit-Lok) attachment system\u003c\/li\u003e\n  \u003cli\u003eCompatible with color-coded soft backup plates for disc identification\u003c\/li\u003e\n  \u003cli\u003eAdapter-ready for M10-1.25, M10-1.50, and 3\/8-24 shafts (adapters sold separately)\u003c\/li\u003e\n  \u003cli\u003eLightweight at 0.33 pounds for reduced operator fatigue\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned for use with 3M Fibre Disc GL attachment system (formerly Grit-Lok) and color-coded soft backup plates.
