Knurled thumb nuts have a cylindrical head with a knurled edge and are designed for easy manual adjustment. The increased head size means that the knurled thumbscrews can be tightened more precisely. Adding a knurled surface to the outside of the head enhances the hand grip.

Unlike similar low-quality components, our thumbscrews are made of brass for overall strength.
