Thumb Screws

 A screw drive that comes with either a tall-headed or ridged (knurled) sides or a key-like flat sided vertical head can be defined as a thumb screw. Thumb screws can easily be tightened or loosened by hand without using any external drive. A thumb screw over-sized head with the diamond-patterned grip finish allows the screw to be tightened or loosened without any external effort. This easy feature makes the screw an imperative part of those devices that require frequent removal and re-installation. Our precision socket head shoulder screws are constructed with steel and feature a zinc finish and are available in a variety of dimensions.
