Description

Brass flat head machine screws provide flush fastening for industrial assemblies. They offer corrosion resistance and a clean surface profile for electronics enclosures, cabinetry, and metal-to-metal interfaces.

Specs

  • Dimensions: Length 38.1 mm (1-1/2 inch); Diameter 6.35 mm (1/4 inch)
  • Finish: Brass
  • Drive type: Spanner drive
  • Material grade: Brass
  • Thread type: 1/4-20 UNC

Features

  • Flush surface and head profile: Flat head seats flush into panels, reducing protrusion and snag risk in enclosures and control interfaces.
  • Corrosion resistance: Brass composition provides inherent resistance to corrosion in indoor and mildly corrosive environments when paired with compatible alloys.
  • Spanner drive efficiency: Spanner drive enables rapid, tool-friendly tightening with minimized cam-out in high-throughput production settings.
  • Thread engagement strength: Coarse 1/4-20 thread offers robust holding power in thin gauge metals and metal-to-metal joints typical of electronics housings and cabinetry.
  • Material compatibility: Best paired with brass or compatible alloys to maintain galvanic compatibility and uniform aesthetics across fastened joints.
  • Typical applications: Electronics enclosures, cabinetry, appliances, and general hardware assemblies requiring flush fastening and corrosion resistance.
  • Installation considerations: Ensure clearance for spanner driver and verify material thickness to achieve full thread engagement; plan for pre-tap when working with thicker panels.
