Knurled thumbscrews have large cylindrical heads with knurled edges 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 handheld grip.

Unlike similar low-quality components, our thumbscrews are constructed from a single piece of solid carbon steel for overall strength.
