The Flange Lock Nut M14 with Tool-Less Finger Tab for an Angle Grinder is a fastening component designed to secure the grinding disc onto the spindle of an angle grinder. The "M14" refers to the size of the threaded nut, which is compatible with tools that have an M14 thread. The tool-less finger tab allows for easy, hand-tightening or loosening of the nut without the need for additional tools, offering convenience and quick disc changes during work. This lock nut ensures that the grinding disc is securely held in place while allowing for easy adjustments or replacements in grinding and cutting applications.
