S-90122A346 Length 1 1/2" Tapping Screws

Key Features & Benefits at a Glance

• Corrosion-resistant alloy steel coating ensures long-lasting performance in demanding industrial environments
• Integrated No. 3 drill tip eliminates pre-drilling requirements, saving significant installation time and labor costs
• 82° countersink angle provides flush mounting in aluminum and sheet metal applications for clean, professional finishes
• Thread forming BSD design creates stronger, more secure threads in ductile materials without chip formation
• Full threading with 14 TPI delivers maximum grip and holding power across the entire 1-1/2" length
• Right-hand thread direction ensures standard installation compatibility and ease of use for technicians
• 0.187" maximum drilling capacity handles standard gauge materials commonly used in metal fabrication

Professional Applications & Engineering Value

These No. 12 Phillips flat head tapping screws are specifically engineered for aluminum and sheet metal applications where corrosion resistance and installation efficiency are critical. The corrosion-resistant alloy steel construction prevents degradation in harsh environments, while the thread forming BSD design creates permanent, vibration-resistant connections without generating metal chips that could compromise electrical components or moving parts. The integrated No. 3 drill tip and 82° countersink angle work together to provide rapid, single-operation installation that reduces labor costs by up to 50% compared to traditional drilling and tapping methods. This makes them ideal for high-volume production environments in HVAC, electronics enclosures, and automotive assemblies where speed, reliability, and clean finishes are essential engineering requirements.

Specification Summary & Compliance

These tapping screws feature precision Class 2A thread tolerances with 0.216" thread diameter and 14 threads per inch specifications. Manufactured to BSD tapping screw standards with standard flat head profile and fully threaded design. Compliant with RoHS 3 (2015/863/EU) environmental regulations, ensuring they meet international standards for hazardous substance restrictions in industrial applications.
