S-91515A460 Length 4" 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 installation with self-drilling No. 3 tip that eliminates pre-drilling and penetrates up to 0.21" steel and sheet metal
• Enhanced driving stability through No. 2 Phillips drive and wide truss head design that resists cam-out and provides superior surface contact
• Maximum holding power with full threading and 14 threads per inch creating secure, vibration-resistant connections in metal substrates
• Increased load distribution from the flanged design that prevents pull-through and reduces surface damage
• Reliable thread formation using BSD thread forming technology that creates strong, precise threads without chip removal
• Environmental compliance meeting RoHS 3 standards for safe, sustainable use across global industrial applications

Professional Applications & Engineering Value

These zinc-plated steel tapping screws deliver exceptional performance in steel and sheet metal applications where durability and installation efficiency are critical. The specialized thread forming design eliminates the need for separate tapping operations, significantly reducing assembly time while creating strong, permanent threads that resist loosening under vibration. The combination of fully threaded construction and self-drilling tip allows for rapid penetration through materials up to 0.21" thick, making them ideal for HVAC systems, metal framing, electrical enclosures, and industrial equipment manufacturing. The flanged truss head provides superior clamping force distribution, preventing material deformation while the zinc plating ensures reliable corrosion protection in challenging environments.

Specification Summary & Compliance

These tapping screws feature precise 0.216" thread diameter with 14 threads per inch and right-hand threading conforming to BSD standards. The 4" length and fully threaded design provide consistent engagement depth, while the No. 2 Phillips drive ensures compatibility with standard industrial tools. Manufactured to exacting tolerances for reliable performance, these screws are RoHS 3 (2015/863/EU) Compliant and suitable for professional industrial applications requiring environmental regulation adherence.
