M3 x 20mm Slotted Grub Screw Cup Point A1 Stainless Steel DIN 438

The M3 x 20mm slotted set screw is more than six and a half times the thread diameter - a very specialist long-reach M3 fastener. At 20mm this headless grub screw is used as a long threaded element rather than a conventional shaft lock: spring-compression adjusters, pressure-setting mechanisms and custom jig assemblies where an M3 thread needs to reach a point deep within a component. Drive with a flat-head screwdriver. The cup end provides clean, controlled contact at the tip. A1 stainless steel throughout. DIN 438 / ISO 7436 compliant.

Common Applications

  • Spring-compression adjusters and pressure-setting mechanisms
  • Custom jig assemblies with extreme depth requirements
  • Long-reach M3 threaded element applications
  • Bespoke equipment where standard lengths are insufficient
