Add these threaded, revolving knobs to your Moxon Vise hand wheels and take them to the next level!  Once affixed, the black knob spins freely so you can quickly spin your moxon vise hand wheels. 

These threads are 1/4 inch x 20.  If you must drill and tap a hole for these knobs to fit into, we recommend using either a #7 or a 13/64ths inch drill to make your hole.  Once the hole is made you must tap it for a 1/4 inch x 20 thread.The threaded knob has a 1/4 inch wide by 1/8th inch deep shoulder on the knob end. You can either drill out a hole for the shoulder to fit into or let it sit proud on the hand wheel.
