S-93945A015 Length 3/4" Tapping Screws

Key Features & Benefits at a Glance

• Superior corrosion resistance with 18-8 stainless steel construction for long-lasting performance in demanding environments
• Efficient thread forming design creates strong, permanent threads in sheet metal without pre-tapping, reducing installation time
• Optimal flush mounting with standard flat head profile and 82° countersink angle for smooth, professional finishes
• Maximum thread engagement through full threading along the entire 3/4" length for enhanced holding power
• Secure drive system featuring square drive No. 2 that resists cam-out and provides reliable torque transmission
• Precision compatibility with No. 29 drill bit (0.136" diameter) for clean installations in materials up to 0.025" thickness
• Regulatory compliance assurance meeting RoHS 3 and REACH standards for safe, environmentally responsible manufacturing

Professional Applications & Engineering Value

These No. 8-15 thread forming tapping screws deliver exceptional engineering value in sheet metal applications where vibration resistance and material integrity are critical. The 18-8 stainless steel composition provides excellent corrosion resistance, making these flat head screws ideal for outdoor equipment, electrical enclosures, and HVAC systems. The thread forming design eliminates the need for separate tapping operations while creating stronger threads through material displacement rather than removal. This cold-forming process work-hardens the surrounding material, resulting in enhanced pull-out strength and vibration resistance. The 82° countersink angle ensures proper seating in standard chamfered holes, while the square drive system prevents stripping during high-torque installation. These features combine to reduce assembly time while providing reliable, long-term fastening solutions for industrial manufacturing and metal fabrication projects.

Specification Summary & Compliance

These precision tapping screws feature No. 8-15 thread specification with 0.164" thread diameter and 15 threads per inch, providing optimal engagement in sheet metal applications. The screws maintain standard dimensional accuracy with fully threaded right-hand threading and pointed tip for easy starting. Manufacturing complies with industry standards for thread forming screws (Type A/AB) and includes full compliance with RoHS 3 (2015/863/EU) and REACH (EC 1907/2006) environmental regulations. The combination of precise dimensional control (0.312" head diameter, 0.1" head height) and regulated material composition ensures consistent performance and environmental responsibility in industrial fastening applications.
