M10 x 20mm Thin Knurled Thumb Screw (DIN 653) | A1 Stainless Steel

For engineering equipment requiring robust hand-operated fastening, this M10 x 20mm knurled machine thumb screw gives operators a simple hand-adjustable fixing with a compact round head. The 36mm diameter provides usable grip while the low 8.0mm head height helps avoid unnecessary projection from the assembly.

What Are Thin Knurled Thumb Screws?

Thin knurled thumb screws are manually operated fasteners intended for assemblies that are opened, adjusted or repositioned without tools. The round head is textured around its edge to improve finger grip while the thin DIN 653 profile reduces head height compared with taller thumb screw styles.

Common Applications

  • Maintenance Panels: Provides a visible manual fixing for equipment inspected on a routine basis.
  • Workshop Assemblies: Fastens substantial removable components where controlled hand torque is appropriate.
  • Heavy Machinery Covers: Provides a substantial hand-operated fixing for removable access components.
  • Industrial Jigs: Secures robust fixture parts that need periodic repositioning.
