This heavy duty knob is perfect where ever you need a knob with 1/2” - 13 UNC threads (1/2” coarse). The main body of the knob is made of glass reinforced nylon. The female thread is a zinc plated steel insert. At 2-5/8” across, there’s lots to grip when tight is what you are looking for.

This knob has been used by the manufacturers of aftermarket table saw fences including:
- Accusquare fence by Mule Cabinetmaker Machine
- Red-Line fence by The Saw Shop
- EZ Square by Peachtree Woodworking Products
If you have one of these fences and have chipped or broken the locking knob, now you can replace it.
