Thumb screw knobs can be press-fit onto screws to create a small knob for clamping or securing quickly and easily with just the thumb and forefinger.

The wide variety of thumb screw knobs we supply can be used with any length screw and come in a variety of knurling patterns or wing-tip designs. They are ideal for applications where space is restricted and fastening with a tool is not possible.

• L-Knob
  

The versatility of thumb screw knobs extends to overlapping styles, including knurled lobed and many others. Browse our online catalog to see every style, size, and application type of thumb screw knob available with the quickest lead times.
