S-93945A033 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.
• Secure square drive system provides excellent torque transmission and minimizes cam-out for reliable fastening.
• 82° countersink angle and flat head ensures a flush, professional finish that eliminates protrusions.
• Full threading along the 3/4" length delivers maximum grip and holding power across the entire fastener.
• Compliance with RoHS 3 and REACH regulations guarantees safe, environmentally responsible materials for industrial use.
• Optimized for No. 21 drill bit (0.159" diameter) ensures precise fit and reduces the risk of material damage during installation.

Professional Applications & Engineering Value

These No. 10-12 thread forming tapping screws are precision-engineered for sheet metal applications, where their 18-8 stainless steel composition provides exceptional resistance to rust and corrosion. The thread forming (Type A/AB) design displaces material to create robust internal threads, eliminating the need for separate tapping operations and reducing assembly costs. The standard flat head with 82° countersink sits perfectly flush, preventing snagging and ensuring a smooth surface—critical in HVAC, electronics enclosures, and automotive panels. Combined with a square drive for high-torque installation and full threading for uniform load distribution, these screws solve common issues like stripping, loosening, and galvanic corrosion, making them a reliable choice for industrial fastening.

Specification Summary & Compliance

This product adheres to standard inch measurements with a No. 10 screw size, 12 threads per inch, and 3/4" length. The thread forming tapping method (Type A/AB) and right-hand thread direction ensure compatibility with typical assembly processes. Manufacturing conforms to industry standards for dimensional accuracy, including the specified 82° countersink angle and 0.362" head diameter. Compliance with RoHS 3 (2015/863/EU) and REACH (EC 1907/2006) is verified, confirming the absence of restricted hazardous substances for safe industrial use.
