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
