S-90048A194 Length 1/2" Tapping Screws

Key Features & Benefits at a Glance

• Superior corrosion resistance with zinc-plated steel construction, ensuring long-lasting performance in industrial environments
• Efficient thread forming technology creates strong, permanent threads in sheet metal without pre-tapping, reducing installation time
• Optimal material compatibility with standard No. 29 drill bit (0.136" diameter) and 82° countersink angle for precise sheet metal applications
• Enhanced driving efficiency with Phillips No. 2 drive and flat head design for flush mounting and secure fastening
• Maximum holding power through fully threaded design and A/AB tapping screw configuration for superior pull-out resistance
• Reliable dimensional accuracy with 0.164" thread diameter and 15 threads per inch ensuring consistent performance
• Comprehensive regulatory compliance meeting RoHS 3 and REACH standards for global industrial applications

Professional Applications & Engineering Value

These No. 8 x 1/2" zinc-plated steel tapping screws are specifically engineered for demanding sheet metal applications where vibration resistance and permanent fastening are critical. The thread forming technology eliminates the need for separate tapping operations, creating stronger threads by displacing material rather than removing it. This results in superior pull-out strength and vibration resistance compared to conventional fasteners. The Phillips flat head design provides flush mounting capabilities while the fully threaded configuration ensures maximum engagement throughout the material thickness. Ideal for HVAC systems, electrical enclosures, and metal fabrication projects, these screws deliver reliable performance in thicknesses up to 0.025", making them essential for precision metalworking applications requiring durable, compliant fastening solutions.

Specification Summary & Compliance

These thread forming tapping screws feature precise dimensional specifications including 0.164" thread diameter, 15 threads per inch, and standard Class 2A thread tolerances. Manufactured as A/AB type tapping screws with right-hand threading and pointed tip for easy starting. The screws comply with RoHS 3 (2015/863/EU) and REACH (EC 1907/2006) regulations, ensuring environmental compliance for industrial applications. Designed for use with standard No. 29 drill bits (0.136" diameter) and 82° countersink angles, providing optimal compatibility with industry-standard sheet metal working practices.
