S-92365A483 Length 4" Tapping Screws

Key Features & Benefits at a Glance

• Eliminates pre-drilling requirements with integrated No. 3 self-drilling tip that penetrates up to 0.22" thickness
• Superior corrosion resistance through zinc-plated steel construction for extended service life in harsh environments
• Secure flush installations enabled by flat head design with 82° countersink angle
• Enhanced driving efficiency with Phillips No. 3 drive that reduces cam-out during installation
• Maximum holding power through fully threaded design and thread forming tapping method
• Broad material compatibility specifically engineered for steel and sheet metal applications
• Precise industrial fit with standardized 1/4"-14 thread configuration for consistent performance

Professional Applications & Engineering Value

These zinc-plated steel tapping screws deliver exceptional value in industrial fastening applications where time efficiency and reliability are paramount. The self-drilling No. 3 tip eliminates the need for separate drilling operations, significantly reducing installation time and labor costs in steel and sheet metal assembly projects. The thread forming design creates strong, permanent threads in parent material without cutting away material, resulting in superior pull-out resistance and vibration resistance. The flat head with 82° countersink ensures clean, flush finishes that meet professional appearance standards while the Phillips drive system provides familiar, reliable driving performance for production line environments. These BSD tapping screws are engineered to withstand the rigors of construction, manufacturing, and metal fabrication applications.

Specification Summary & Compliance

These 1/4"-14 tapping screws feature standard inch measurements with fully threaded right-hand configuration. Manufactured to industry standards for thread forming screws with BSD specification, they ensure consistent performance across applications. The zinc-plated steel construction provides corrosion protection while maintaining mechanical strength. The screws are designed with precision Class 2A thread tolerances and feature a standardized 82° countersink angle for proper seating in prepared holes. Compliant with RoHS and REACH environmental standards, these industrial fasteners meet the demanding requirements of professional construction and manufacturing applications.
