S-90064A717 Length 1" Tapping Screws

Key Features & Benefits at a Glance

• Superior corrosion resistance with zinc-plated steel construction for extended service life in demanding industrial environments
• Maximum torque transmission through external hex head design, preventing tool slippage during installation
• Self-drilling capability with specialized tip that eliminates pre-drilling requirements, saving time and labor costs
• Enhanced holding power through fully threaded design and flanged head that distributes clamping force evenly
• Reliable thread forming action creates strong, permanent threads in steel and sheet metal without material removal
• Optimized for 0.08" maximum thickness materials, making them ideal for various metal fabrication applications
• Precision threading with 24 threads per inch ensures consistent, secure fastening performance

Professional Applications & Engineering Value

These No. 4-24 thread forming tapping screws deliver exceptional value in metal fabrication and assembly operations. The zinc-plated steel construction provides reliable corrosion protection while maintaining high tensile strength for demanding applications. The combination of external hex drive and thread forming design eliminates common installation issues - the hex head prevents cam-out during high-torque applications, while the thread forming action creates stronger, more durable threads in steel and sheet metal by displacing material rather than cutting it. This results in superior resistance to vibration loosening and higher pull-out strength compared to traditional fasteners. The integrated drilling tip with 9/64" length streamlines assembly processes by combining drilling and fastening into a single operation, significantly reducing labor time and costs in high-volume production environments.

Specification Summary & Compliance

These BSD tapping screws feature precision No. 4-24 thread specifications with Class 2A thread tolerance for consistent fit and performance. The fully threaded 1" length design ensures maximum engagement in materials up to 0.08" thickness. Manufactured to industry standards for thread forming screws, these fasteners comply with RoHS and REACH environmental regulations and are engineered for reliable performance in steel and sheet metal applications. The right-hand thread direction and 0.112" thread diameter provide standardized compatibility with existing tooling and assembly processes.
