S-90064A715 Length 1/2" Tapping Screws

Key Features & Benefits at a Glance

• Eliminates pre-drilling requirements with integrated drilling tip that penetrates up to 0.08" thick steel and sheet metal
• Superior corrosion resistance through zinc-plated steel construction for extended service life in industrial environments
• Maximum torque transmission via external hex drive design that prevents tool slippage during installation
• Enhanced fastening security with flanged design that distributes clamping force over wider surface area
• Full thread engagement along the entire 1/2" length ensures consistent holding power in metal applications
• Thread forming capability creates stronger, more durable threads in parent material without chip removal
• Standardized dimensions with No. 4-24 BSD thread specification for reliable compatibility across applications

Professional Applications & Engineering Value

These zinc-plated steel tapping screws deliver exceptional value in metal fabrication and assembly operations where efficiency and reliability are paramount. The thread forming design eliminates the need for separate tapping operations while creating stronger, more vibration-resistant connections in steel and sheet metal applications. The integrated drilling tip penetrates up to 0.08" thickness without pre-drilling, significantly reducing installation time and labor costs. The external hex drive provides superior torque transmission for high-volume production environments, while the flanged head distributes clamping force to prevent material distortion in thin-gauge metals. These BSD tapping screws are engineered specifically for demanding industrial applications where fast, secure metal-to-metal fastening is essential.

Specification Summary & Compliance

This No. 4-24 x 1/2" tapping screw features precision inch system measurements with fully threaded right-hand BSD thread form and Class 2A thread tolerances. The product meets industrial standards for thread forming screws with 0.112" thread diameter and 24 TPI thread pitch. Manufactured from zinc-plated steel with external hex drive and flanged head design, these screws comply with industry specifications for metal fastening applications and contain materials that meet RoHS and REACH environmental standards.
