S-93945A051 Length 1" Tapping Screws

Key Features & Benefits at a Glance

• Superior corrosion resistance with 18-8 stainless steel construction, ensuring long-lasting performance in demanding industrial environments.
• Efficient thread forming design that creates strong, reliable threads in sheet metal without pre-tapping, reducing installation time and labor costs.
• Secure square drive system providing excellent torque transmission and minimizing cam-out for consistent, reliable fastening.
• Optimized 82° countersink angle allowing for flush mounting in sheet metal applications, creating clean, professional finishes.
• Full threading along the 1" length ensures maximum grip and holding power throughout the entire engagement area.
• Right-hand threading with standard A/AB profile for compatibility with existing tools and industry-standard practices.
• Environmental compliance assurance meeting RoHS 3 and REACH regulations for safe, sustainable industrial use.

Professional Applications & Engineering Value

These thread forming tapping screws are specifically engineered to address common challenges in sheet metal fabrication and assembly. The 18-8 stainless steel composition provides exceptional resistance to corrosion and oxidation, making these flat head screws ideal for applications exposed to moisture, chemicals, or outdoor elements. The thread forming design eliminates the need for separate tapping operations by displacing material to create strong, permanent threads that resist vibration loosening. The square drive configuration ensures maximum torque transfer without stripping, while the standard 82° countersink angle allows the flat head to sit flush with the material surface. This combination of features makes these A/AB tapping screws particularly valuable in HVAC systems, electrical enclosures, automotive components, and industrial machinery where reliable, vibration-resistant fastening is critical.

Specification Summary & Compliance

These No. 12 tapping screws feature a 1" length with fully threaded right-hand design and standard thread profile. The screws maintain precise dimensional accuracy with a 0.216" thread diameter and 11 threads per inch. Installation requires a 3/16" drill bit (0.1875" diameter) and is suitable for materials up to 0.025" thickness. The products are manufactured in compliance with RoHS 3 (2015/863/EU) and REACH (EC 1907/2006) regulations, ensuring environmental safety and regulatory adherence for industrial applications.
