Flat Knurled Thumb Screws DIN 653

EH 24770.

Knurled thumb screws are very versatile. Three material versions for the different requirements

  • steel, blackened
  • steel, zinc-plated by galvanization
  • stainless steel

are available.

Knurled thumb screws can be easily tightened and released by hand. The ribbed outer surface of the nut prevents slipping when tightening / releasing with the fingers.

The thread is manufactured up to the head and with runout without undercut at the end of the thread (DIN designation A). The screws can therefore not be screwed in up to the head.
