M5 x 22mm Thin Knurled Thumb Screw (DIN 653) | A1 Stainless Steel

For workshop fixtures and test equipment, this M5 x 22mm knurled machine thumb screw gives operators a simple hand-adjustable fixing with a compact round head. The 20mm diameter provides usable grip while the low 4.0mm head height helps avoid unnecessary projection from the assembly.

What Are Thin Knurled Thumb Screws?

DIN 653 screws are useful when a standard machine thread is needed together with a head designed for direct hand operation. Their low head profile helps conserve space around panels and instruments while the knurling gives a dependable gripping surface.

Common Applications

  • Workshop Fixtures: Fastens adjustable parts that operators need to release regularly.
  • Test Equipment: Provides controlled hand fastening for fixtures used during repeated trials.
  • Machine Panels: Secures service panels that are removed during inspection or maintenance.
  • Production Jigs: Allows stops, guides and fixture parts to be repositioned without tools.
