Knurled Thin Thumb Screws - DIN 653.

What are Knurled Thin Thumb Screws - DIN 653?

Thin 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 is available through our custom manufacture service.

As an alternative product, Accu also offers a selection of Wing Screws, which are also designed to be adjusted by hand.
