Overview

NSI Industries QDS172 is a precision #12 sheet metal screw engineered for secure, self-piercing fastening in metal applications. This USA-made fastener features a 1-1/4" length, 5/16" head width, and hex head for compatibility with standard tools. The quadrive drive type ensures reliable torque transfer, while the zinc chromate finish provides corrosion resistance in industrial environments. Each pack contains 100 screws, optimized for use with the MT210B Chuck for efficient installation. The self-piercing design eliminates pre-drilling in thin materials up to 1/8" thickness, reducing labor time and improving workflow efficiency. Ideal for sheet metal fabrication, HVAC systems, and general metalworking projects requiring a durable, self-tapping solution. Compatible with steel substrates, this screw delivers consistent performance in high-volume production settings.
