S-90048A108 Length 3/8" Tapping Screws

Key Features & Benefits at a Glance

• Superior corrosion resistance with zinc-plated steel construction, ensuring long-term durability in demanding industrial environments
• Effortless installation through thread-forming design that creates strong, permanent threads in sheet metal without pre-tapping
• Maximum holding power with fully threaded shank and pointed tip for secure fastening in thin materials up to 0.025" thickness
• Optimized flush mounting featuring standard 82° flat head profile that sits perfectly countersunk in sheet metal applications
• Reliable drive engagement with Phillips No. 1 drive style preventing cam-out during high-torque installation
• Precision thread engagement with 24 threads per inch and 0.112" diameter ensuring consistent performance in sheet metal assemblies
• Regulatory compliance meeting RoHS 3 and REACH standards for safe use in global industrial applications

Professional Applications & Engineering Value

These zinc-plated steel tapping screws are specifically engineered for sheet metal applications where reliable fastening in thin materials is critical. The thread forming design eliminates the need for separate tapping operations, reducing assembly time and labor costs while creating stronger threads than cutting alternatives. The fully threaded configuration and pointed tip ensure immediate engagement and maximum thread contact throughout the material thickness. With their 82° countersink angle and flat head profile, these screws provide flush mounting that prevents snagging and maintains aerodynamic surfaces in HVAC systems, electronic enclosures, and automotive panels. The Phillips drive offers familiar, efficient installation while the zinc plating provides essential corrosion protection for industrial environments.

Specification Summary & Compliance

This No. 4-24 x 3/8" tapping screw features precision right-hand threads with 24 threads per inch and 0.112" thread diameter, manufactured to standard A/AB tapping screw specifications. The screw requires a No. 44 drill bit (0.086" diameter) for proper installation in materials up to 0.025" maximum thickness. Compliance includes RoHS 3 (2015/863/EU) and REACH (EC 1907/2006) regulations, ensuring environmental safety and regulatory acceptance for industrial use worldwide.
