Industrial Applications

Cheese Head Screws are widely used in:

  • Electrical panels and assemblies: Fit in tight spaces and offer a deep slot for reliable driving without stripping.
  • Automotive components: Ensure secure fastening of precision parts where both strength and aesthetics matter.
  • Machinery and equipment: Provide stable joints that withstand high loads and vibrations.
  • Construction fittings and hardware: Ideal for casings, enclosures, and structural elements needing a neat finish.
  • Aerospace and defense systems: Deliver high-strength fastening with durability under extreme conditions.

Product Description

The Cheese Head Screw is distinguished by its cylindrical head design, resembling a wheel of cheese, offering a larger bearing area than many other screws. This shape, combined with deep slots, allows secure tightening and reduced tool slippage. Available in multiple sizes, materials, and protective coatings, these screws balance strength, corrosion resistance, and visual neatness—making them versatile for both mechanical and aesthetic applications.
