S-90190A108 Length 3/8" Tapping Screws

Key Features & Benefits at a Glance

• Superior corrosion resistance with zinc-plated steel construction, extending service life in demanding industrial environments
• Excellent thread-forming capability creates permanent, vibration-resistant connections in sheet metal without pre-tapped holes
• Optimized drive engagement with Phillips No. 1 drive prevents cam-out and ensures efficient installation
• Maximum material penetration with fully threaded design and pointed tip for superior holding power in thin materials
• Wide compatibility with standard No. 44 drill bits (0.086" diameter) for simplified installation processes
• Reliable pan head design provides a balanced combination of low profile and sufficient bearing surface
• Industry compliance assurance with RoHS 3 and REACH regulations for global manufacturing applications

Professional Applications & Engineering Value

These No. 4-24 thread forming tapping screws deliver exceptional performance in sheet metal applications where traditional fastening methods fall short. The zinc-plated steel construction provides essential corrosion protection for industrial environments, while the A/AB thread forming technology eliminates the need for pre-tapped holes by displacing material to create strong, permanent threads. This thread forming method significantly reduces installation time and prevents loose connections caused by vibration. The fully threaded design ensures maximum engagement throughout the material thickness, providing superior pull-out resistance in thin-gauge metals up to 0.025". The combination of Phillips drive system and pan head profile offers reliable installation with standard tools while maintaining a low-profile appearance ideal for applications where clearance is limited.

Specification Summary & Compliance

These tapping screws feature precise No. 4-24 thread specifications with 0.112" thread diameter and 24 threads per inch, manufactured to standard thread forming tolerances. The 3/8" length and fully threaded design ensure consistent performance across applications. Compliance with RoHS 3 (2015/863/EU) and REACH (EC 1907/2006) regulations guarantees these fasteners meet current environmental and safety standards for industrial use worldwide.
