S-93878A199 8-32 x 1" Tapping Screws

Key Features & Benefits at a Glance

• Exceptional corrosion resistance with zinc-plated steel construction, ensuring long-lasting performance in harsh industrial environments.
• Superior thread-forming capability for reliable, vibration-resistant fastening in steel, aluminum, brass, and cast iron without pre-tapping.
• Optimized torque transfer via Phillips No. 2 drive, reducing cam-out risks and enabling efficient installation with standard tools.
• Full-length threading maximizes grip and load distribution, providing enhanced holding power across the entire fastener length.
• Wide material compatibility allows versatile use in diverse applications, from sheet metal assemblies to heavy-duty castings.
• Coarse UNC 8-32 thread ensures quick installation and strong engagement in softer metals and plastics.
• Compliance with global regulations including RoHS 3 and REACH, making them suitable for international supply chains and eco-conscious projects.

Professional Applications & Engineering Value

These zinc-plated steel thread forming tapping screws are engineered to address common industrial challenges like material fatigue and assembly efficiency. The thread forming design creates precise mating threads in ductile materials—such as steel, aluminum, and brass—eliminating the need for separate tapping operations and reducing installation time. The Phillips drive ensures consistent torque application, minimizing strip-outs in high-volume production lines. With a coarse 8-32 UNC thread and blunt tip, they provide excellent pull-out resistance in sheet metal and cast components, making them ideal for HVAC systems, machinery frames, and automotive subassemblies where vibration resistance and durability are critical.

Specification Summary & Compliance

This product adheres to UNC coarse thread standards with a size of 8-32 and 1" length, manufactured to standard dimensional tolerances for reliable interchangeability. The zinc-plated steel finish enhances corrosion protection, while the thread forming (SW type) design ensures robust performance in non-ferrous and ferrous metals. Compliant with RoHS 3 (2015/863/EU) and REACH (EC 1907/2006) regulations, these screws meet stringent environmental and safety requirements for industrial and export applications.
