S-95641A148 Length 1/2" Tapping Screws

Key Features & Benefits at a Glance

• Superior corrosion resistance with 18-8 Stainless Steel construction, ensuring long-lasting performance in harsh industrial environments.
• Enhanced tamper resistance and secure fastening thanks to the Tri-Wing® drive style, reducing the risk of unauthorized removal.
• Excellent thread retention in sheet metal through thread forming technology, which creates strong, reliable threads without pre-tapping.
• Optimized for quick installation with a pointed tip and fully threaded design, allowing for faster driving and reduced assembly time.
• Reliable holding power from the 18 TPI and 0.138" thread diameter, providing a secure fit in materials up to 0.025" thickness.
• Broad compatibility with standard No. 32 drill bits (0.116" diameter), simplifying the preparation process in sheet metal applications.
• Compliance with major environmental regulations including RoHS 3 and REACH, ensuring safe use in global industrial supply chains.

Professional Applications & Engineering Value

This No. 6 x 1/2" Tri-Wing® tapping screw is engineered for demanding sheet metal applications, where vibration resistance and durability are critical. Made from 18-8 Stainless Steel, it offers exceptional corrosion resistance, reducing maintenance costs in environments exposed to moisture or chemicals. The thread forming design displaces material to form precise internal threads, eliminating the need for pre-tapped holes and minimizing the risk of strip-out in thin-gauge metals. With its Tri-Wing® drive, it provides tamper-resistant security, ideal for assemblies in automotive, electronics, and HVAC systems. The combination of a pan head and fully threaded shank ensures consistent clamping force, making it a reliable choice for high-volume manufacturing and repair operations.

Specification Summary & Compliance

This fastener features a thread diameter of 0.138" with approximately 18 threads per inch, conforming to standard thread forming (Type A/AB) specifications for sheet metal. It is designed for use with a No. 32 drill bit (0.116" diameter) and supports maximum material thickness up to 0.025". The screw complies with RoHS 3 (2015/863/EU) and REACH (EC 1907/2006) regulations, ensuring it is free from hazardous substances and suitable for industrial applications requiring environmental and safety standards.
