Benefits #

At 3/8-inch, inch-series stainless steel pan head screws provide reliable threaded connections in US-specification corrosive environment assemblies. The pan head provides a wider bearing surface than round head alternatives. A2 stainless steel construction is appropriate for marine, food processing, and architectural applications where inch-dimensioned fasteners are specified.

Common Applications #

  • Industrial equipment (inch spec)
  • Heavy machinery panel attachment
  • Marine deck hardware (inch)
  • Architectural metalwork (inch)
  • Large appliance assembly (inch)
