S-93945A042 Length 1 3/4" Tapping Screws

Key Features & Benefits at a Glance

• Superior corrosion resistance with 18-8 stainless steel construction, ideal for harsh industrial environments and long-term reliability.
• Efficient thread forming design creates strong, permanent threads in sheet metal without pre-tapping, reducing assembly time and labor costs.
• Secure, high-torque driving enabled by the square drive style, minimizing cam-out and tool slippage for consistent installation.
• Flush, low-profile seating with the standard 82° flat head, providing a smooth surface finish and improved aesthetic in assembled products.
• Full-length threading ensures maximum grip and holding power across the entire 1-3/4" length, enhancing joint integrity.
• Optimized for 0.025" sheet metal with precise No. 21 drill bit compatibility, delivering reliable performance in standard thickness applications.
• Compliance with global regulations including RoHS 3 and REACH, ensuring safe, environmentally responsible sourcing for international projects.

Professional Applications & Engineering Value

These No. 10-12 thread forming tapping screws are engineered specifically for sheet metal applications, where vibration resistance, material integrity, and installation speed are critical. The 18-8 stainless steel composition provides excellent resistance to oxidation and chemical exposure, making these screws suitable for outdoor equipment, HVAC systems, and electronic enclosures. The A/AB tapping screw type with a pointed tip and fully threaded design allows for easy starting and consistent thread engagement, reducing the risk of strip-out in thin-gauge metals. This design minimizes the need for additional fastening components, streamlining assembly lines and lowering total cost of ownership for high-volume manufacturing operations.

Specification Summary & Compliance

This fastener meets Class 2A thread tolerances for reliable fit and is manufactured as a right-hand threaded, fully threaded screw with a standard 82° countersink angle. It conforms to industry-standard dimensional requirements for tapping screws used in sheet metal. The product is fully RoHS 3 (2015/863/EU) Compliant and REACH (EC 1907/2006) Compliant, adhering to strict environmental and safety regulations for hazardous substances.
