S-93878A144 6-32 x 1/4" Tapping Screws

Key Features & Benefits at a Glance

• Superior corrosion resistance with zinc-plated steel construction, extending service life in demanding industrial environments.
• Efficient installation and reduced assembly time thanks to the thread-forming design that creates strong threads without pre-tapping in materials like steel and aluminum.
• Enhanced drive stability and reduced cam-out with the Phillips No. 2 drive, ensuring secure fastening and minimizing tool slippage.
• Reliable holding power in coarse-thread applications using UNC 6-32 threading, ideal for securing components in sheet metal and cast iron.
• Versatile material compatibility for use in steel, aluminum, brass, and cast iron, simplifying inventory for diverse projects.
• Consistent full-length threading provides uniform load distribution and improved fastener integrity across the entire shank.
• Compliance with global environmental standards including RoHS 3 and REACH, ensuring safe and sustainable use in regulated industries.

Professional Applications & Engineering Value

These zinc-plated steel tapping screws are engineered to address common challenges in industrial assembly, such as material fatigue and installation inefficiency. The thread-forming (SW type) design eliminates the need for separate tapping operations, reducing labor costs and the risk of cross-threading in steel, aluminum, brass, and cast iron applications. With a Phillips pan head and UNC coarse threads, they deliver exceptional clamp load and vibration resistance, making them ideal for sheet metal fabrication, machinery enclosures, and automotive components. The blunt tip and fully threaded shank ensure precise alignment and consistent performance, enhancing durability in high-stress environments while maintaining compliance with industry regulations.

Specification Summary & Compliance
