S-90064A330 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 capability creates permanent, vibration-resistant threads without chip removal in steel and sheet metal
• Integrated drilling tip design eliminates pre-drilling requirements, saving time and labor costs on assembly lines
• External hex drive system provides maximum torque transmission and prevents tool slippage during installation
• Flanged head design distributes clamping force evenly and eliminates the need for separate washers
• Full threading along 1/2" length ensures consistent engagement and superior holding power throughout the fastener
• Regulatory compliance assurance with RoHS 3 certification for environmentally responsible manufacturing standards

Professional Applications & Engineering Value

These No. 8 zinc-plated steel tapping screws deliver exceptional engineering value in steel and sheet metal applications where reliability is critical. The thread forming design creates stronger, more durable connections by displacing material rather than removing it, resulting in superior resistance to vibration loosening. The integrated drilling tip with 3/16" length penetrates up to 0.098" thickness without pilot holes, significantly reducing installation time and labor costs in high-volume manufacturing. The external hex drive and flanged head work in concert to provide excellent torque transmission and clamping force distribution, making these BSD tapping screws ideal for automotive, HVAC, and industrial equipment assembly where consistent performance is non-negotiable.

Specification Summary & Compliance

These thread forming screws feature precision 0.164" thread diameter with 18 threads per inch and are manufactured to BSD tapping screw standards. The 1/4" hex head provides reliable drive engagement while the fully threaded 1/2" length ensures maximum holding power. Compliance with RoHS 3 (2015/863/EU) regulations confirms environmental responsibility and industrial-grade quality standards for global manufacturing applications.
