S-95639A476 Length 1 1/4" Tapping Screws

Key Features & Benefits at a Glance

• Superior corrosion resistance with 316 stainless steel construction, ideal for harsh industrial environments and outdoor applications.
• Efficient thread-forming design creates strong, permanent threads in sheet metal without pre-tapping, reducing installation time and labor costs.
• Secure and flush finishing provided by the standard oval head with an 82° countersink angle, minimizing protrusion and improving safety.
• Reliable drive engagement using a Phillips No. 3 drive, ensuring consistent torque application and reducing cam-out risks.
• Full threading along the 1-1/4" length maximizes grip and load distribution in materials up to 0.025" thickness.
• Compliance with RoHS 3 and REACH regulations ensures environmental safety and global market acceptability for your products.
• Precision sizing (No. 14, 10 threads per inch) guarantees consistent performance and interchangeability in automated or manual assembly.

Professional Applications & Engineering Value

These 316 stainless steel oval head Phillips tapping screws are engineered to address common challenges in sheet metal fabrication, such as material fatigue and corrosion-induced failure. The thread-forming (Type A/AB) design displaces material to create robust threads without chips, enhancing joint integrity in thin-gauge metals. This is critical for enclosures, HVAC systems, and automotive panels where vibration resistance and a smooth finish are paramount. The fully threaded shank and pointed tip facilitate quick starts and even stress distribution, reducing the risk of stripping. Combined with high corrosion resistance, these screws deliver long-term reliability in demanding conditions, from marine to chemical processing settings.

Specification Summary & Compliance

This product adheres to standard inch measurements with a thread diameter of 0.242" and 10 threads per inch, ensuring precise fit in pre-drilled 5.5mm (0.2165") holes. The oval head profile and 82° countersink angle conform to industry norms for flush mounting. Manufacturing complies with RoHS 3 (2015/863/EU) and REACH (EC 1907/2006) regulations, confirming the absence of restricted hazardous substances. Designed for thread-forming applications in materials like sheet metal, these screws meet functional requirements for maximum drilling thickness of 0.025".
