S-90064A582 Length 1 1/2" Tapping Screws

Key Features & Benefits at a Glance

• Eliminates pre-drilling requirements with integrated No. 3 drill tip that penetrates up to 0.187" steel and sheet metal, saving labor time and tooling costs.
• Superior corrosion resistance from zinc-plated steel construction, ensuring long-term reliability in harsh industrial or outdoor environments.
• Enhanced fastening security with the flanged design, distributing clamp load over a wider area to prevent loosening under vibration.
• Exceptional holding power through thread forming BSD technology, creating strong, permanent threads in ductile materials without chip removal.
• Efficient installation with external hex drive and hex head, allowing for high-torque application using standard tools.
• Full-length threading provides consistent grip along the entire 1-1/2" length, maximizing pull-out strength in assembled components.
• Broad material compatibility specifically engineered for steel and sheet metal applications in construction and industrial assembly.

Professional Applications & Engineering Value

This No. 12-14 flanged tapping screw addresses critical challenges in metal fabrication and construction. The zinc-plated steel construction combats environmental corrosion while maintaining high tensile strength. Its self-drilling tip eliminates the costly, time-consuming pre-drilling step in assembly lines, significantly reducing installation time in sheet metal and steel frameworks. The thread forming BSD design creates precise, zero-clearance threads that resist vibration-induced loosening—crucial for HVAC systems, electrical enclosures, and structural panels. The external hex drive and flanged head work synergistically to provide reliable clamp force distribution, preventing material distortion in thin-gauge applications while allowing rapid installation with common hex tools.

Specification Summary & Compliance

This No. 12 size screw features a 1-1/2" length with 14 threads per inch and fully threaded right-hand configuration. Manufactured to BSD tapping screw standards with precise thread forming tolerances. The zinc-plated steel material and manufacturing process comply with industry standards for corrosion protection and mechanical performance. Meets relevant industrial specifications for self-drilling screws used in metal fastening applications.
