S-94195A425 Length 2 3/4" Tapping Screws

Key Features & Benefits at a Glance

• Eliminates pre-drilling with integrated No. 3 drill tip, saving significant labor time and costs in steel and sheet metal assembly
• Superior corrosion resistance provided by 410 stainless steel material, ensuring long-term reliability in harsh industrial environments
• Exceptional holding power through BSD thread forming design that creates strong, permanent threads in parent material
• Clean, flush installation with standard flat head profile and 82° countersink angle for smooth finished surfaces
• Maximum material penetration capability drilling through up to 0.14" thickness of steel and stainless steel
• Full-length threading provides consistent grip along the entire 2-3/4" length for enhanced load distribution
• Optimized driving efficiency with Phillips No. 3 drive style that reduces cam-out and improves installation control

Professional Applications & Engineering Value

These self-drilling tapping screws are engineered to solve critical challenges in metal fabrication and industrial assembly. The 410 stainless steel construction delivers excellent strength and corrosion resistance, while the integrated No. 3 drill tip with 11/32" length eliminates the need for separate drilling operations. The BSD thread forming design creates precise, tight-fitting threads in steel, stainless steel, and sheet metal applications, preventing loosening under vibration and thermal cycling. The 82° countersink angle and flat head profile ensure flush mounting in structural components, HVAC systems, and metal building applications where surface finish matters. These fully threaded fasteners provide maximum pull-out resistance, making them ideal for demanding industrial environments where reliability is paramount.

Specification Summary & Compliance

These No. 12 size self-drilling screws feature precise inch system measurements with 0.216" thread diameter and 14 threads per inch. The right-hand threads follow standard industrial specifications, while the thread forming tapping method ensures consistent performance. The manufacturing process adheres to industry standards for dimensional accuracy, with the flat head design maintaining proper 82° countersink compatibility. These industrial fasteners are manufactured to meet quality control standards suitable for professional metalworking and construction applications.
