Product Description

The 3M 7010298962 is a flange nut designed to secure 4 inch x 1/4 inch x 5/8 inch CH 3M Unitized Wheels and DCGW grinding wheels to compatible angle grinders. The nut features a 3/8-24 internal thread and includes a 5/8 inch diameter x 0.062 inch high centering boss that keeps the wheel properly indexed during operation. The 1 inch diameter, 1/8 inch thick flange distributes clamping force evenly and allows wheel use in confined or close-quarter workspaces.
