S-91515A440 Length 3" Tapping Screws

Key Features & Benefits at a Glance

• Superior corrosion resistance with zinc-plated steel construction for extended service life in demanding industrial environments
• Enhanced drilling efficiency with specialized No. 3 drill tip that penetrates up to 0.175" thick steel and sheet metal without pre-drilling
• Increased load distribution from the wide flanged truss head design that prevents pull-through and provides superior clamping force
• Reliable thread forming with BSD type tapping creates strong, permanent threads in metal substrates without chip removal
• Optimized drive performance through Phillips No. 2 drive that ensures secure tool engagement and reduces cam-out during installation
• Full-threaded design delivers maximum holding power along the entire 3" length for superior fastening in thick materials
• Environmental compliance with RoHS 3 standards ensures safe, sustainable manufacturing for global industrial applications

Professional Applications & Engineering Value

These No. 10 x 3" zinc-plated steel tapping screws are engineered specifically for steel and sheet metal applications where drilling and fastening operations must be combined for efficiency. The thread forming BSD design creates durable, high-strength threads in metal substrates without generating chips, eliminating cleanup time and potential contamination in sensitive equipment. The flanged truss head provides exceptional bearing surface that distributes clamping force over a wider area, preventing material distortion in thin-gauge metals. With a No. 3 drill tip capable of penetrating up to 0.175" thickness, these screws eliminate the need for separate drilling operations, significantly reducing installation time and labor costs in HVAC, electrical enclosures, and metal fabrication projects.

Specification Summary & Compliance

This tapping screw features a 0.19" thread diameter with 16 TPI right-hand threading and fully threaded 3" length. Manufactured to BSD screw type standards with thread forming tapping method and Class 2A thread tolerances. The zinc-plated steel construction provides reliable corrosion protection while maintaining RoHS 3 (2015/863/EU) compliance for environmental safety. The Phillips No. 2 drive system ensures compatibility with standard industrial drivers, making these screws suitable for high-volume production environments requiring consistent performance and regulatory adherence.
