Thumb Screws feature a knurled cylindrical head, and are designed to be easily adjusted by hand. The increased head diameter of a Thumb Screw allows these fasteners to be adjusted to a precise tightness by hand.
DIN 465 Thumb Screws are also available with an unthreaded section below the head for captivation. The captive variant of this product can be found in Accu's Slotted Captive Thumb Screw range.
As an alternative product, Accu also offers a selection of Wing Screws, which are also designed to be adjusted by hand.
Components within this range are available in a number of specialist materials, including A1, A2 and A4 Stainless Steel, Brass, Phosphor Bronze, Nylon and PEEK. Additional features such as Chemical Blackening and Thread Locking Patches can also be applied to these products.
