Clamp Knob Assembly 286303-00

This is a single OEM clamp knob assembly for a saw. The clamp knob is what secures the blade in the saw blade clamp. This assembly has a wingnut cast onto a threaded metal stud. With use, the clamping surface will deteriorate, which causes the blade to slip. The threads on the metal stud can also start to strip. For this quick and easy repair, you will need to disconnect the blade, and then unscrew and remove the clamp knob from the blade chuck. To install your new part, fasten the clamp knob into the blade chuck and reassemble the blade.
