S-93945A011 Length 1/2" Tapping Screws

Key Features & Benefits at a Glance

• Superior corrosion resistance with 18-8 stainless steel construction, ensuring long-term reliability in harsh industrial environments
• Efficient thread forming design creates strong, permanent threads in sheet metal without pre-tapping, reducing installation time and labor costs
• Optimal flush mounting with standard 82° flat head profile and countersink angle for smooth, professional finishes in sheet metal assemblies
• Enhanced torque transmission through square drive (No. 2) design, preventing cam-out and ensuring secure fastening in high-vibration applications
• Maximum grip strength with fully threaded pointed tip construction, providing complete engagement through material thickness up to 0.025"
• Precision thread engagement with No. 8-15 thread specification (0.164" diameter, 15 TPI) ensuring consistent performance across sheet metal applications
• Environmental compliance assurance meeting RoHS 3 and REACH standards for safe, sustainable manufacturing practices

Professional Applications & Engineering Value

These 18-8 stainless steel flat head tapping screws deliver exceptional engineering value in sheet metal fabrication and assembly operations. The thread forming (A/AB type) design eliminates the need for separate tapping operations by cold-forming mating threads directly into sheet metal substrates, significantly reducing assembly time and tooling requirements. The combination of fully threaded construction and pointed tip geometry ensures immediate engagement and maximum thread contact throughout the material thickness, preventing loosening under vibration while distributing load evenly. The 82° countersink angle provides flush mounting in standard chamfered holes, creating clean, professional appearances while maintaining structural integrity. These characteristics make these square drive tapping screws ideal for HVAC systems, electronic enclosures, automotive panels, and industrial equipment where corrosion resistance, installation efficiency, and reliable performance are critical.
