Product Description

M3X20MM round thumb screw with flat knurled head style. Knurled head provides extra grip for manual tightening. Usually found on thumb screws, a knurled surface on the head gives a better gripping surface, making it easier to tighten or loosen fasteners manually. Thumb screws are designed to be tightened and loosened by hand. Tools not necessary for tightening or loosening knurled thumb screws are installed with your fingers and are used to hold light covers in place and other ornamental products.
