S-92365A485 Length 1/2" Tapping Screws

Key Features & Benefits at a Glance

• Eliminates pre-drilling requirements with integrated drilling tip that penetrates up to 0.09" thickness in steel and sheet metal
• Superior corrosion resistance thanks to the durable black-oxide steel coating that withstands harsh industrial environments
• Maximum thread engagement and holding power achieved through fully threaded design and thread forming (BSD) technology
• Clean, flush installation enabled by the standard flat head profile with 82° countersink angle
• Reliable driving performance with Phillips No. 2 drive that prevents cam-out during high-torque applications
• Precise dimensional consistency with No. 6-20 thread specification ensuring uniform performance across all installations
• Reduced assembly time and labor costs through combined drilling and fastening operation in a single component

Professional Applications & Engineering Value

These black-oxide steel tapping screws deliver exceptional value in industrial fastening applications where steel and sheet metal assemblies require reliable, permanent connections. The thread forming (BSD) design creates stronger threads in parent material by displacing rather than removing material, eliminating chip accumulation issues common in traditional tapping. The fully threaded configuration ensures maximum grip length while the specialized drilling tip (No. 2 type) penetrates up to 0.09" thickness without pilot holes, significantly reducing installation steps. The 82° countersink angle provides a flush finish that meets aerospace and automotive surface requirements, while the Phillips drive system offers familiar, efficient installation for production line environments.

Specification Summary & Compliance

These No. 6-20 x 1/2" tapping screws feature precise Class 2A thread tolerances with 0.138" thread diameter and 20 threads per inch. Manufactured to BSD (Thread Forming) standards with right-hand threading and round shank cross-section. The black-oxide surface treatment provides corrosion protection while maintaining dimensional integrity. Components comply with RoHS and REACH environmental directives and are manufactured according to industrial fastener specifications for consistent performance in demanding applications.
