S-93880A108 Length 3/8" Tapping Screws

Key Features & Benefits at a Glance

• Superior corrosion resistance through zinc-plated steel construction, extending service life in demanding industrial environments
• Efficient installation with external hex drive compatibility and flanged head design that eliminates the need for separate washers
• Strong, permanent thread formation in sheet metal without pre-tapping requirements, reducing installation time and labor costs
• Optimized for No. 44 drill bits (0.086" diameter) with blunt tip design that prevents material damage during installation
• Full threading along the 3/8" length ensures maximum grip and load distribution across the entire fastener engagement
• Right-hand thread direction provides standard installation compatibility with conventional driving tools
• Flanged head design distributes clamping force over a wider surface area (0.243" diameter) to prevent material distortion

Professional Applications & Engineering Value

This No. 4-24 thread forming tapping screw delivers exceptional value in sheet metal fabrication and assembly operations. The zinc-plated steel construction provides reliable protection against corrosion in industrial environments, while the thread forming technology creates strong, permanent threads in base materials without the need for pre-tapped holes. The flanged hex head design combines the installation efficiency of external hex drive compatibility with the load distribution benefits of an integrated washer, eliminating component count and simplifying inventory. Engineered specifically for use with No. 44 drill bits (0.086" diameter), this fully threaded blunt tip screw ensures precise alignment and prevents material splitting during installation, making it ideal for high-volume manufacturing applications where reliability and installation speed are critical.

Specification Summary & Compliance

This inch system fastener features precision No. 4-24 threads with standard right-hand thread direction and fully threaded design. Manufactured to industry standards for thread forming tapping screws (Type B), the screw is compatible with No. 44 drill bits (0.086" diameter) and features a flanged hex head (0.188" width, 0.079" height) for secure installation. The zinc-plated steel construction meets industry requirements for corrosion resistance and is compliant with RoHS and REACH environmental standards for industrial fasteners.
