Thumb screws are ideal for temporary connections that require frequent adjustments. They feature a large, knurled head that can be installed tool-free by hand for a quick and easy adjustment or removal. Thumb screws utilize machine screw threads to they can be pre-drilled or tap the same as for standard machine screws. The thread sizing is consistent too allowing a variety of options to fit the project requirements.
