S-90077A310 Length 1/2" Tapping Screws

Key Features & Benefits at a Glance

• Superior corrosion resistance with zinc-plated steel construction for extended service life in demanding industrial environments
• Efficient thread forming technology creates strong, permanent threads in sheet metal without pre-tapping requirements
• Dual-drive compatibility with Phillips/Slotted head accommodates various tooling preferences and reduces installation time
• Maximum holding power achieved through fully threaded design and 10 threads per inch for secure, vibration-resistant fastening
• Optimized pan head design provides excellent bearing surface and prevents countersinking in sheet metal applications
• Precision dimensional accuracy with 0.242" thread diameter and Class 2A thread tolerances ensures consistent performance
• Environmental compliance meets RoHS 3 and REACH standards for safe use in regulated industries

Professional Applications & Engineering Value

These No. 14 zinc-plated steel tapping screws deliver exceptional engineering value in sheet metal fabrication and assembly operations. The thread forming design eliminates the need for separate tapping operations, significantly reducing installation time and labor costs while creating strong, permanent threads that resist loosening under vibration. The zinc-plated steel construction provides reliable corrosion protection in industrial environments, while the Phillips/Slotted drive combination offers flexibility for various assembly line tooling systems. The fully threaded configuration ensures maximum engagement throughout the entire fastener length, distributing clamping force evenly and preventing material distortion in thin-gauge sheet metal applications up to 0.025" thickness.

Specification Summary & Compliance
