S-90190A109 Length 7/16" 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 design creates strong, reliable threads in sheet metal without pre-tapping, reducing installation time and tooling costs.
• Optimized for 0.025" maximum drilling thickness, providing precise fastening in thin sheet metal applications with minimal material distortion.
• Phillips pan head drive offers secure tool engagement and a low-profile finish for clean, professional assemblies.
• Fully threaded pointed tip enables quick, self-starting installation and consistent holding power across the entire screw length.
• Compliance with RoHS 3 and REACH regulations ensures safe, environmentally responsible use in global industrial supply chains.
• Standardized No. 4-24 thread size guarantees interchangeability and reliable performance in OEM and maintenance applications.

Professional Applications & Engineering Value

These zinc-plated steel tapping screws are engineered to address common challenges in sheet metal fabrication, such as strip-out and loose fasteners. The thread forming (Type A/AB) design displaces material rather than cutting it, creating stronger threads with improved resistance to vibration and pull-out. The Phillips drive and pan head provide a balanced combination of torque transmission and a smooth, low-profile finish, ideal for HVAC systems, electronic enclosures, and automotive panels. With a pointed tip and fully threaded shank, these screws reduce installation effort and ensure consistent clamping force, making them a reliable choice for high-volume production lines and field service repairs where durability and compliance are critical.

Specification Summary & Compliance

This screw meets standard inch dimensions with a thread diameter of 0.112" and 24 threads per inch, ensuring precise fit in pre-drilled holes using a No. 44 drill bit (0.086" diameter). Manufactured as a Type A/AB thread forming tapping screw with right-hand threading, it is fully compliant with RoHS 3 (2015/863/EU) and REACH (EC 1907/2006) regulations, confirming its suitability for restricted substance-controlled industrial and export applications.
