S-90056A145 Length 5/16" 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 thread forming action creates strong, permanent threads in sheet metal without requiring pre-tapped holes
• Optimized drive engagement with Phillips No. 2 drive provides secure tool connection and reduces cam-out during installation
• Maximum thread contact through fully threaded design ensures superior holding power across the entire fastener length
• Precision blunt tip design allows for easier starting and prevents damage to sensitive materials during assembly
• Reliable compliance assurance with RoHS 3 regulations for environmentally responsible manufacturing standards
• Versatile pan head profile offers excellent bearing surface for secure fastening in various sheet metal thicknesses

Professional Applications & Engineering Value

These No. 6-20 thread forming screws deliver exceptional performance in sheet metal applications where traditional fastening methods fall short. The zinc-plated steel construction provides essential corrosion protection for industrial environments, while the Type B thread forming design eliminates the need for separate tapping operations, significantly reducing assembly time and labor costs. The Phillips drive system ensures consistent torque application, and the fully threaded configuration maximizes pull-out resistance in thin-gauge materials. Engineered with a blunt tip and precise 20 TPI threading, these tapping screws prevent material splitting while creating strong, reliable threads that withstand vibration and thermal cycling in metal fabrication, HVAC systems, and electronic enclosures.

Specification Summary & Compliance

This thread forming Type B screw features a No. 6-20 thread with 0.138" diameter and 5/16" length, designed for use with No. 32 drill bits (0.116" diameter). Manufactured with Class 2A thread tolerances for consistent fit and performance, these zinc-plated steel fasteners comply with RoHS 3 (2015/863/EU) regulations, ensuring they meet current environmental standards for industrial components. The right-hand threaded, fully threaded design with pan head profile provides reliable fastening solutions for professional sheet metal assembly requirements.
