S-92685A420 Length 3/4" 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 installation with thread forming technology that creates strong, permanent threads without pre-tapping requirements
• Enhanced grip and stability from the flanged hex head design that distributes load evenly and prevents loosening
• Quick penetration through the integrated drilling tip that eliminates need for pilot holes in steel and sheet metal
• Secure fastening with serrated locking features that resist vibration and maintain clamp force
• High torque capability from the external hex drive that allows for powerful installation with standard tools
• Maximum material thickness coverage with 0.187" drilling capacity for versatile application across various metal gauges

Professional Applications & Engineering Value

These No. 12 zinc-plated steel tapping screws deliver exceptional performance in steel and sheet metal applications where vibration resistance and structural integrity are critical. The thread forming technology creates precise mating threads that eliminate the risk of cross-threading while providing superior pull-out strength compared to conventional fasteners. The combination of fully threaded design and No. 3 drilling tip enables rapid installation without pre-drilling, significantly reducing assembly time in manufacturing, construction, and metal fabrication. The flanged hex head with serrations provides a wide bearing surface that prevents sinking into softer materials while maintaining secure fastening under dynamic loads. These BSD tapping screws are engineered to solve common industrial challenges including material fatigue, corrosion, and installation efficiency.

Specification Summary & Compliance

These thread forming screws feature precision Class 2A thread tolerances with 14 threads per inch and 0.216" thread diameter. Manufactured to BSD standards for tapping screw applications, they comply with RoHS and REACH environmental directives. The right-hand threaded design with fully threaded shank ensures consistent performance across the entire 3/4" length. The external hex drive (0.313" across flats) and 0.52" flange diameter provide optimal torque transmission and load distribution capabilities for industrial fastening requirements.
