S-92365A484 Length 3/4" Tapping Screws

Key Features & Benefits at a Glance

• Self-drilling capability eliminates pre-drilling requirements, saving significant labor time and reducing installation costs in steel and sheet metal applications
• Zinc-plated steel construction provides excellent corrosion resistance for extended service life in demanding industrial environments
• Thread forming technology (BSD) creates stronger, more secure fastenings by displacing material rather than removing it
• 82° countersink angle ensures flush mounting with material surfaces for clean, professional finishes
• Maximum drilling thickness of 0.22" handles substantial material depths commonly encountered in metal fabrication projects
• Fully threaded design delivers maximum holding power along the entire screw length for superior fastening integrity
• Phillips flat head with No. 4 drive offers reliable installation with common tools while maintaining low-profile aesthetics

Professional Applications & Engineering Value

These 5/16" zinc-plated steel tapping screws are engineered specifically for demanding steel and sheet metal applications where drilling and fastening operations need to be combined for efficiency. The thread forming BSD technology eliminates the need for separate tapping operations by creating precise internal threads through material displacement, resulting in stronger thread engagement and reduced stress concentrations. The No. 3 drill tip with specialized geometry penetrates up to 0.22" thick materials while the 82° countersink angle ensures proper seating in standard countersunk holes. This combination of features makes these Phillips flat head screws ideal for HVAC systems, metal framing, electrical enclosures, and industrial equipment assembly where vibration resistance and long-term reliability are critical.

Specification Summary & Compliance

These tapping screws feature precise 0.312" thread diameter with 12 threads per inch in right-hand thread configuration, manufactured to BSD tapping screw standards. The 3/4" length and fully threaded design provide consistent fastening performance. The zinc-plated steel construction meets industry standards for corrosion protection, while the manufacturing process complies with relevant industrial fastening specifications for dimensional accuracy and mechanical properties suitable for professional applications in metalworking and construction sectors.
