S-94059A546 Length 1 1/2" Tapping Screws

Key Features & Benefits at a Glance

• Superior corrosion resistance with zinc-plated steel construction for extended service life in demanding industrial environments
• Integrated sealing protection through steel/rubber washers that prevent moisture ingress and maintain joint integrity
• Efficient self-drilling capability with 5/16" No. 3 drill tip that eliminates pre-drilling and reduces installation time
• High-torque installation enabled by external hex drive design for secure fastening in steel and sheet metal applications
• Reliable thread forming action with BSD tapping method that creates strong, vibration-resistant threads without chip removal
• Full-length threading ensures maximum grip and load distribution across the entire 1-1/2" length
• Environmental compliance with RoHS 3 standards for safe use in regulated industrial settings

Professional Applications & Engineering Value

These 1/4"-14 thread forming screws deliver exceptional value in steel and sheet metal fabrication where vibration resistance and environmental sealing are critical. The zinc-plated steel construction provides durable corrosion protection, while the integrated steel/rubber sealing washer creates reliable barriers against moisture and contaminants. The BSD tapping method and fully threaded design ensure superior holding power in materials up to 0.21" thickness, eliminating the need for separate drilling operations. The external hex drive accommodates high-torque installation tools, making these tapping screws ideal for HVAC systems, electrical enclosures, and structural metal assemblies where long-term performance is essential.

Specification Summary & Compliance

These 1/4"-14 thread forming screws feature precision right-hand threads with 14 threads per inch and Class 2A thread tolerances for consistent performance. The 3/8" hex head with 0.341" height provides optimal tool engagement, while the 5/8" OD flat washer ensures proper load distribution. Manufactured to BSD tapping screw standards with fully RoHS 3 (2015/863/EU) compliant materials, these screws meet international environmental regulations for industrial fastener applications.
