S-93878A148 6-32 x 1/2" Tapping Screws

Key Features & Benefits at a Glance

• Superior corrosion resistance with zinc-plated steel construction, extending service life in demanding industrial environments
• Efficient thread forming creates strong, permanent threads in metal without pre-tapping, reducing installation time and labor costs
• Broad material compatibility for reliable performance in steel, aluminum, brass, cast iron, and sheet metal applications
• Secure Phillips drive engagement with No. 2 drive size prevents cam-out and ensures consistent torque application
• Optimized pan head design provides a low-profile finish with excellent bearing surface for secure fastening
• Full UNC coarse threading delivers rapid installation and superior pull-out resistance in various metal substrates
• Environmental compliance meets RoHS 3 and REACH standards for safe use in regulated industries

Professional Applications & Engineering Value

These zinc-plated steel tapping screws are engineered specifically for metal fabrication and assembly applications where reliable fastening is critical. The thread forming design (SW type) eliminates the need for separate tapping operations, creating precise mating threads that resist vibration loosening and provide excellent fatigue resistance. The UNC coarse thread pattern ensures quick installation in steel, aluminum, brass, and cast iron components, while the fully threaded shank maximizes engagement strength across the entire fastener length. The Phillips drive system with No. 2 size offers familiar, efficient installation with standard tools, making these screws ideal for high-volume production environments requiring consistent, repeatable results in sheet metal assemblies, machinery components, and structural frameworks.

Specification Summary & Compliance

These 6-32 x 1/2" tapping screws feature UNC coarse threading with Class 2A tolerance for reliable fit and performance. The thread forming design conforms to SW type specifications for creating threads in pre-drilled holes (recommended drill bit size: #30/0.1285"). Manufacturing and material compliance includes full adherence to RoHS 3 (2015/863/EU) and REACH (EC 1907/2006) environmental regulations, ensuring these fasteners meet current industry standards for restricted substances and chemical safety in industrial applications.
