Product Description

Hand screws (also known as thumbscrews) are versatile fasteners designed for manual tightening and loosening without requiring tools. Their tool-free operation makes them ideal for applications where space constraints prevent the use of screwdrivers or wrenches.

These fasteners are particularly useful for components requiring frequent removal, such as panels, covers, or maintenance access points. Their large, knurled heads provide excellent grip for hand tightening, and some models include a screwdriver slot for additional installation options.

Key Features:
  • Knurled head design for enhanced grip during manual installation
  • Available in various sizes and custom lengths
  • High-strength carbon steel construction
  • Galvanized finish with blue zinc coating for corrosion resistance
  • DIN standard compliant
  • Self-tapping design for easy installation
Applications

Thumb screws are widely used in:

  • Panel fastening and enclosure systems
  • Equipment covers and access panels
  • Electronics and appliance assemblies
  • Industrial machinery requiring frequent maintenance access
  • Woodworking and specialized construction applications
