Thumb screws are unique in that they can be adjusted by hand and don’t need any tools to fasten or remove them. Thumb screws are ideal for projects with space restrictions or build features that prohibit the use of screwdrivers or wrenches, such as safety covers and panels, or applications where frequent adjustment or removal is needed.
WM Berg thumb screws are available in 303 stainless steel with a knurled black plastic head, knurled stainless steel head or knurled stainless steel socket head. Available thread sizes include 4-40, 6-32, 8-32, 10-24, 10-32, ¼-20 UNC/UNF (M1.6 x .35, M2 x .4, M3 x .5, M4 x .7, M5 x .8, M6 x 1.0, M8 x 1.25, M10 x 1.5mm).
