S-93945A022 Length 1 1/2" Tapping Screws

Key Features & Benefits at a Glance

• Superior corrosion resistance with 18-8 stainless steel construction for long-lasting performance in harsh industrial environments
• Maximum torque transmission through square drive design, preventing cam-out and ensuring secure installation
• Excellent thread-forming capability creates strong, permanent threads in sheet metal without pre-tapping requirements
• Full threading along the entire 1-1/2" length provides consistent holding power throughout the fastened material
• Precision 82° countersink angle ensures flush mounting in sheet metal applications for clean, professional finishes
• Optimized for 0.025" maximum drilling thickness delivering reliable performance in standard sheet metal assemblies
• Environmental compliance assurance with RoHS 3 and REACH regulations for safe, sustainable industrial use

Professional Applications & Engineering Value

These No. 8-15 thread forming screws are engineered specifically for sheet metal applications where reliable fastening is critical. The 18-8 stainless steel composition provides exceptional resistance to corrosion and oxidation, making these flat head tapping screws ideal for outdoor equipment, electrical enclosures, and HVAC systems. The thread forming design (A/AB type) displaces material rather than cutting it, creating stronger threads that resist vibration loosening. With their square drive configuration, these screws deliver maximum torque transfer during installation, reducing the risk of stripped heads and ensuring consistent seating in the 82° countersink. The fully threaded shank and 0.164" thread diameter with 15 threads per inch provide optimal grip in materials up to 0.025" thickness, making them essential for precision metal fabrication and assembly operations.

Specification Summary & Compliance

These tapping screws feature precision No. 8-15 thread specifications with 0.164" thread diameter and 15 threads per inch, designed for use with No. 29 drill bits (0.136" diameter). The flat head profile with standard dimensions (0.312" head diameter, 0.1" head height) ensures proper seating in prepared countersinks. Manufacturing and material compliance includes full adherence to RoHS 3 (2015/863/EU) and REACH (EC 1907/2006) regulations, confirming these fasteners meet current environmental and safety standards for industrial applications.
