S-91515A920 Length 1 7/8" Tapping Screws

Key Features & Benefits at a Glance

• Eliminates pre-drilling requirements with integrated drilling tip that penetrates up to 0.098" steel and sheet metal
• Superior corrosion resistance through zinc-plated steel construction for extended service life in industrial environments
• Enhanced load distribution from the wide truss head design with integrated flange for secure fastening
• Optimized driving efficiency with Phillips No. 2 drive that prevents cam-out during installation
• Maximum thread engagement through fully threaded design that ensures superior holding power
• Reliable thread formation using BSD thread forming technology that creates strong, permanent connections
• Environmental compliance meeting RoHS 3 standards for safe use in regulated applications

Professional Applications & Engineering Value

These No. 8-18 flanged truss head tapping screws are engineered specifically for demanding steel and sheet metal applications where traditional fastening methods fall short. The zinc-plated steel construction provides essential corrosion protection while maintaining high tensile strength. The innovative thread forming design with BSD tapping screw technology creates precise threads in parent material without chip formation, eliminating the risk of contamination in sensitive assemblies. The combination of fully threaded shank and wide truss head with integrated flange distributes clamping force evenly, preventing material distortion in thin-gauge applications. The drilling tip penetrates up to 0.098" thickness, significantly reducing installation time and labor costs by eliminating pre-drilling operations in industrial manufacturing and metal fabrication environments.

Specification Summary & Compliance

This No. 8-18 x 1-7/8" tapping screw features precise 0.164" thread diameter with 18 threads per inch in right-hand orientation. Manufactured to BSD tapping screw standards with thread forming methodology for optimal performance in steel and sheet metal substrates. The product maintains dimensional accuracy with Class 2A thread fit and complies with RoHS 3 (2015/863/EU) regulations for environmental safety. The zinc-plated steel construction ensures consistent performance while the Phillips No. 2 drive provides reliable installation compatibility with standard industrial tools.
