5インチ ソリッド 5/16-24 ネジシャンク 米国製 H&L

The threading on this disc is precise and clean, so it screws onto my backing pad without any wobble. It holds the sandpaper firmly through a full project, which is exactly what I needed.

Finally found a 5/16-24 thread that threads on smooth without any wobble, and the hook-and-loop backing grabs the disc tight with no slippage mid-project. Made in the USA, the shank feels solid and hasn't stripped after a dozen swaps.

These discs hold up perfectly under heavy use, and the hook-and-loop backing keeps them securely in place during sanding. The 5-inch size is exactly what I needed for my detail work.
