M6 x 12mm Thin Knurled Thumb Screw (DIN 653) | A1 Stainless Steel

Suitable for machinery guards and removable covers, this M6 x 12mm hand-tightened knurled fastener offers tool-free tightening without the bulk of a high-profile thumb screw. A 24mm head diameter provides leverage for hand operation while the 5.0mm head height helps keep the fixing discreet.

What Are Thin Knurled Thumb Screws?

This type of knurled fastener is intended for controlled hand tightening. The slim round head keeps the fixing close to the component surface and the textured edge makes repeated removal practical on equipment that is inspected, serviced or reconfigured regularly.

Common Applications

  • Control Equipment: Provides a low-profile hand fixing for covers and service panels.
  • Laboratory Rigs: Supports repeatable repositioning of clamps, holders and instrument parts.
  • Inspection Fixtures: Fastens adjustable components used during quality checks.
  • Assembly Equipment: Provides convenient access to parts changed during setup.
