Benefits #

Stainless steel countersunk self-tapping screws at ST2.9 (#4) gauge eliminate separate tapping operations while providing flush mounting in corrosive environments. The 80° flat head seats level with the material surface, preventing snagging. A2 (304) stainless steel eliminates coating degradation in humid and atmospheric environments. Self-tapping thread cuts into sheet metal, plastics, and composites without pre-tapping. This gauge serves thin-gauge enclosure assembly, HVAC ductwork, and electrical panel fabrication.

Common Applications #

Common applications for ST2.9 (#4) stainless steel countersunk self-tapping screws include:

  • Thin-gauge enclosure assembly
  • Small electrical box fabrication
  • Light-duty HVAC ductwork
  • Appliance housing assembly
  • Small signage mounting
