Description

Machine Screws Combo Pan Steel Black Oxide 1/4-20 x 1/2 are durable, ready-to-use fasteners designed for reliable metal-to-metal assemblies. Built with rugged steel and finished in black oxide, these screws deliver strength and a clean, low-profile appearance for a wide range of projects.

Product Highlights

  • Head style: Pan head for a broad bearing surface and comfortable drive
  • Material: Steel for strong, long-lasting fastening
  • Finish: Black oxide provides mild corrosion resistance and a `satin`-like appearance
  • Thread size: 1/4-20 UNC (Unified Coarse) for common, versatile fastening
  • Length: 1/2 inch to suit a variety of material thicknesses

These machine screws are ideal for general hardware fasteners, cabinetry, appliance repair, electronics enclosures, and metalwork where a secure, flush profile is desired. The combination of a pan head with a durable steel body makes them suitable for both DIY projects and professional applications.

Why choose black oxide steel screws? The black oxide finish enhances corrosion resistance for everyday use, reduces glare, and pairs well with darker hardware kits. The robust steel construction provides dependable torque and retention, ensuring a solid hold in a variety of assemblies.

Usage tips: Ensure proper thread engagement by aligning with a compatible nut or tapped hole. Use a compatible driver and avoid over-tightening to prevent stripping. For best results, pilot holes and thread clearance should match the screw size and material being fastened.
