S-91515A420 Length 2" 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 fastening stability through the wide truss head design that provides superior load distribution and prevents pull-through
• Efficient installation with Phillips No. 2 drive that ensures secure tool engagement and reduces stripping during high-torque applications
• Self-drilling capability featuring a No. 2 drill tip that eliminates pre-drilling requirements, saving time and labor costs
• Reliable thread formation using BSD thread forming technology that creates strong, permanent threads in steel and sheet metal
• Maximum grip strength with full threading along the 2" length for secure fastening across the entire engagement area
• Regulatory compliance meeting RoHS 3 standards for safe use in various industrial applications

Professional Applications & Engineering Value

These No. 8 zinc-plated steel tapping screws are engineered to address critical challenges in steel and sheet metal fabrication. The combination of thread forming technology and self-drilling tip eliminates the need for separate drilling and tapping operations, significantly reducing assembly time while creating stronger, more reliable connections. The wide truss head design provides exceptional bearing surface that distributes clamping force effectively, preventing material deformation in thin-gauge applications. With the ability to drill through up to 0.098" thickness and form precise BSD threads, these Phillips drive screws deliver consistent performance in HVAC systems, electrical enclosures, metal framing, and industrial equipment assembly where vibration resistance and long-term reliability are paramount.

Specification Summary & Compliance

These thread forming tapping screws feature precise 0.164" thread diameter with 18 threads per inch and Class 2A thread tolerances for consistent fit. Manufactured to BSD standards with fully threaded design and flanged truss head configuration. The screws are RoHS 3 (2015/863/EU) Compliant, ensuring they meet current environmental and safety regulations for industrial use in various markets.
