Discover more about the Knurled High Thumb Screws - DIN 464 range.

Knurled High Thumb Screws feature a large cylindrical head with a knurled edge, and are designed to be easily adjusted by hand. An increased head size means that Knurled Thumb screws can be tightened with a greater degree of accuracy.

The addition of a knurled surface on the outside of the head enhances grip and control for installation by hand. Unlike similar lower-quality components, Accu's DIN 464 Thumb Screws are manufactured from one piece of solid Stainless Steel, giving excellent overall strength.

Thumb Screw Variants

Our Knurled High Thumb Screws feature a shoulder beneath the head, however for a variant without a shoulder, please see our Knurled Thin Thumb Screws - DIN 653 range.

Accu also offers an alternative head type in our range of Slotted Thumb Screws - DIN 465, which can be tightened using a Slotted (Flat Head) Screwdriver.

DIN 464 Thumb Screws are also available in a Captive Screw variant, which can be found in Accu's Knurled Captive Thumb Screw range.

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


This range is manufactured from A1 (303) Stainless Steel as standard, with Blackened and Thread Locking Patch finishes also available. Additional materials and finishes can be requested through our custom manufacture service.

Metric Knurled Thumb Screws

Knurled Thumb Screws are manufactured to the DIN 464 standard, and are available in metric diameters of between M3 and M10, and in lengths from 4.00mm up to 30.00mm. Non-standard sizes can also be specially manufactured on request.
