Overview

The NSi Industries JDS83 is a 12 x 3 inch indented hex washer head slotted tapping screw made from steel with a zinc plating finish. This screw is designed for secure fastening in metal-to-metal applications where thread-forming is required. The indented hex washer head provides a flush surface while offering a larger bearing area for improved load distribution. The slotted drive design ensures accurate thread engagement and reduces cam-out during installation. The zinc plating delivers corrosion resistance, making it suitable for indoor and protected outdoor environments. Typical applications include machinery assembly, automotive components, electrical enclosures, and general metal fabrication where a self-tapping screw is required. The 5/16 inch slot drive accommodates standard slotted screwdrivers, ensuring compatibility with common tooling. This tapping screw eliminates the need for pre-tapped holes, reducing assembly time and simplifying installation in sheet metal and thin metal sections. The JDS83 is part of NSi Industries' JDS series of indented hex head slotted tapping screws available in steel zinc and stainless steel variants for corrosion resistance or enhanced durability.
