M6 x 25mm Thin Knurled Thumb Screw (DIN 653) | A1 Stainless Steel

Frequently selected for machinery guards and removable covers, this M6 x 25mm low-profile thumb screw delivers hand tightening in a compact DIN 653 form. The textured head edge supports positive grip and the 25mm thread offers additional threaded reach through thicker components or spaced assemblies without introducing a separate knob or handle.

What Are Thin Knurled Thumb Screws?

A low-profile knurled thumb screw combines a standard metric thread with a broad hand-operated head. The reduced head thickness keeps the fixing compact while the knurled perimeter provides the friction needed for controlled manual tightening.

Common Applications

  • Inspection Fixtures: Fastens adjustable components used during quality checks.
  • Assembly Equipment: Provides convenient access to parts changed during setup.
  • Machinery Guards: Secures removable guarding where regular access is part of maintenance.
  • Production Tooling: Allows fixture components to be adjusted or removed between jobs.
