S-98903A361 Length 3/4" Tapping Screws

Key Features & Benefits at a Glance

• Superior corrosion resistance with 18-8 stainless steel construction for extended service life in demanding industrial environments
• Efficient thread forming technology creates strong, permanent threads in sheet metal without pre-tapping, reducing installation time and labor costs
• Precise 82° countersink angle ensures flush mounting with sheet metal surfaces for clean, professional finishes
• Optimized Phillips drive design with No. 3 drive size provides secure tool engagement and reduces cam-out during installation
• Full threading along the entire 3/4" length delivers maximum grip strength and uniform load distribution
• Undercut flat head profile allows deeper seating and improved clamping force without surface protrusion
• Environmental compliance assurance with RoHS 3 and REACH regulations for safe, sustainable industrial applications

Professional Applications & Engineering Value

These Type A thread forming screws are specifically engineered for sheet metal applications where reliable fastening and corrosion resistance are critical. The 18-8 stainless steel composition provides excellent strength and durability against environmental factors, while the thread forming design eliminates the need for separate tapping operations, significantly reducing assembly time and costs. The 82° countersink angle and undercut flat head work together to create seamless, flush installations that prevent snagging and maintain aerodynamic surfaces. Compatible with standard 3/16" drill bits and designed for maximum drilling thickness of 0.025", these fully threaded screws ensure consistent performance across various sheet metal gauges in HVAC, electronics enclosures, and industrial equipment manufacturing.

Specification Summary & Compliance

These No. 12 x 3/4" tapping screws feature precise right-hand threads with approximately 11 threads per inch and 0.216" thread diameter. Manufactured to Type A thread forming standards with fully threaded configuration and pointed tip for easy starting. The screws maintain strict dimensional accuracy with 0.412" head diameter and 0.092" head height. Compliance includes RoHS 3 (2015/863/EU) and REACH (EC 1907/2006) regulations, ensuring environmental safety and regulatory adherence for industrial applications.
