Overview

The NSI Industries QK20M is a self-piercing sheet metal screw engineered for efficient and secure fastening in various industrial applications. This screw features a #10 size and a 1/2 inch length, with a 1/4 inch hex head for easy driving with a #8 driver size. Constructed from steel with a durable Zinc Chromate finish, it offers good corrosion resistance for extended service life. The self-piercing design allows for direct insertion into sheet metal without the need for a pre-drilled pilot hole, significantly speeding up assembly processes. This makes the QK20M ideal for applications such as HVAC ductwork, automotive panel assembly, electrical enclosures, and general metal fabrication where speed and reliability are paramount. Each pack contains 1000 screws, providing a cost-effective solution for high-volume projects. For optimal performance and ease of use, this screw is designed for use with the MT208B Chuck. The hex head ensures a strong grip, minimizing cam-out and ensuring consistent torque application. The Zinc Chromate finish provides a protective barrier against environmental factors, contributing to the longevity of the fastened joint. When precise and rapid sheet metal assembly is required, the NSI QK20M offers a dependable and efficient fastening solution.
