Benefits #

Inch-series stainless steel pan head machine screws at #1/8 (inch) provide corrosion-resistant fastening in US-specification equipment. The pan head distributes clamping force across a wide bearing surface. A2 (304) stainless steel eliminates coating degradation in humid and atmospheric environments. Phillips drive allows controlled torque application with standard drivers. This diameter serves legacy US-specification machinery, marine hardware, and aerospace interior assemblies.

Common Applications #

Common applications for #1/8 inch-series SS pan head machine screws include:

  • Small US-spec instrument panels
  • Legacy equipment assembly (inch)
  • Marine interior fittings (inch)
  • Small electrical enclosures (inch)
  • Aerospace interior panels (inch)
