Thumb Screw Knobs

In stock

Thumb screw knobs can be press-fit onto screws to create a small knob for clamping or securing. These knobs can be used with any length screw and are easily tightened with just a thumb and forefinger. They are ideal for applications where space is restricted and fastening with a tool is not possible.
