Knurled Thumb Screws - DIN 653

What are Knurled Thumb Screws - DIN 653?

Knurled Thumb Screws (DIN 653) feature a large cylindrical head with a knurled edge, and are designed to be easily adjusted by hand. The large head diameter of these fasteners also allows them to be tightened with a greater degree of accuracy, and a knurled head enhances grip. Unlike other low-quality plastic components, AccuGroup's DIN 653 Knurled Thumb Screws are manufactured entirely from solid Stainless Steel, giving excellent overall strength.

These products feature no shoulder, which allows the head to sit flush with a target housing. For a shouldered variant of this product, please see AccuGroup's DIN 464 Knurled Thumb ScrewsAccuGroup also offers an alternative product, Slotted Thumb Screws, which can be tightened using a Slotted Screwdriver.

AccuGroup also offers a range of Wing Screws, which are similarly adjusted by hand.


DIN 653 Knurled Thumb Screws are manufactured from A1 Stainless Steel as standard, with additional materials available on request. Chemical Blackening and Thread Locking Patches are also available.


DIN 653 Knurled Thumb Screws can be manufactured in thread sizes of between M2 and M10, and in lengths from 4.00mm to 40.00mm. Head Diameters range from 8.71mm up to 36.50mm.
