• Full threading along the 1-1/4" length ensures maximum grip and holding power across the entire fastener.
• Reliable drive engagement with a Phillips No. 1 drive, reducing cam-out and enabling efficient installation.
• RoHS 3 compliance ensures environmental safety and meets strict international regulatory standards.
• Pan head design with a rounded profile provides a finished appearance and good bearing surface.

Professional Applications & Engineering Value

This No. 4-24 thread forming screw is engineered to solve common challenges in sheet metal assembly. The 18-8 stainless steel material offers excellent resistance to rust and corrosion, which is critical for outdoor enclosures, HVAC systems, and electrical cabinets exposed to moisture. The Type B thread forming technology displaces material to create strong, load-bearing internal threads, eliminating the need for a separate tapping operation and reducing assembly time and cost. The combination of a Phillips drive and a pan head ensures straightforward installation with standard tools while providing a secure clamp. These fully threaded screws deliver consistent performance in fastening thin materials, making them a reliable choice for high-volume manufacturing and maintenance operations where durability and efficiency are paramount.

Specification Summary & Compliance

This screw features a thread diameter of 0.112" with approximately 24 threads per inch, conforming to standard inch-series specifications for tapping screws. The right-hand thread and fully threaded shank ensure uniform engagement. It is designed for use with a No. 44 drill bit (0.086" diameter) for optimal performance in sheet metal. The product is manufactured to be RoHS 3 (2015/863/EU) Compliant, adhering to environmental regulations and ensuring it is free from hazardous substances.
