Description

Machine Screws Slotted Flat 18/8 Stainless 4/40 x 7/16 deliver dependable performance for metal assemblies where a flush, secure fastening is essential. Crafted from 18/8 stainless steel, these screws resist corrosion and maintain strength in a variety of environments, making them ideal for both indoor and exposed applications.

  • Material: 18/8 stainless steel (304 grade) for excellent corrosion resistance and durability.
  • Head style: Slotted flat head for a low-profile, flush finish in countersunk holes.
  • Drive type: Slotted drive compatible with standard flat-blade screwdrivers.
  • Size and length: #4-40 thread, 7/16 inch long.
  • Finish: Polished stainless steel finish that resists moisture, chemicals, and wear.
  • Applications: Perfect for electronics enclosures, cabinetry, machinery, appliances, and other metal-to-metal assemblies.
  • Compatibility: Designed to work with corresponding 4-40 nuts or tapped holes.

Why choose these screws: they combine the reliability of stainless steel with a classic slotted drive and a low-profile flat head, ensuring a clean appearance and dependable performance in precision fastenings. Use them in assemblies where corrosion resistance and a precise, flush finish are required, and pair with compatible nuts or tapped holes for secure, long-lasting joints.

Tip: Always prepare pre-tapped pilot holes and avoid over-tightening to prevent thread damage. Stainless steel screws resist corrosion but should be installed with appropriate torque to maintain strength and alignment.
