S-91515A020 Length 1 3/4" Tapping Screws

Key Features & Benefits at a Glance

• Superior corrosion resistance with zinc-plated steel construction, extending service life in industrial environments
• Enhanced load distribution through the wide flanged truss head design, reducing surface damage and improving joint integrity
• Efficient installation with No. 2 Phillips drive for maximum torque transfer and reduced cam-out during driving
• Self-drilling capability with integrated No. 3 drill tip, eliminating pre-drilling and saving labor time on steel/sheet metal up to 0.175" thick
• Optimal thread engagement through fully threaded BSD thread forming design, providing superior pull-out resistance in metal substrates
• Wide application versatility with 1-3/4" length and 0.19" diameter, suitable for various steel and sheet metal thickness combinations
• Secure fastening performance with 16 TPI thread pitch ensuring tight, vibration-resistant connections in demanding applications

Professional Applications & Engineering Value

Engineered for steel and sheet metal applications, this zinc-plated steel tapping screw addresses critical industrial fastening challenges. The flanged truss head design provides a larger bearing surface that distributes clamping force effectively, preventing material distortion in thin-gauge metals. Its thread forming BSD configuration creates strong, permanent threads in parent material without chip removal, eliminating tapping operations and reducing assembly time. The integrated No. 3 drill tip penetrates up to 0.175" thickness, making it ideal for HVAC systems, electrical enclosures, and metal framing where drilling and fastening must occur simultaneously. The fully threaded construction ensures maximum thread engagement along the entire shank, delivering exceptional pull-out strength and vibration resistance in high-stress environments.

Specification Summary & Compliance

This No. 10-16 x 1-3/4" tapping screw features precision thread forming with BSD standard compliance, right-hand threading, and 16 threads per inch. Manufactured to industry standards for tapping screws, it maintains consistent dimensional accuracy with 0.19" thread diameter and 0.433" flange diameter. The zinc-plated finish provides corrosion protection while meeting RoHS and REACH environmental compliance requirements for industrial fasteners.
