Overview

NSi Industries JTEKD99 is a #14 self-drilling and tapping screw engineered for metal-to-metal and metal-to-wood fastening in industrial, construction, and repair applications. Made from durable steel with a zinc chromate finish, this screw measures 4 inches in length with a 3/8-inch hex washer head for increased bearing surface and reduced pull-through. The hex drive type (#3 drill size) ensures secure engagement with standard drivers, eliminating the need for pre-drilling holes. This single-step installation reduces labor time by up to 50% compared to conventional screws, making it ideal for high-volume projects. The zinc chromate finish provides corrosion resistance in indoor and outdoor environments, extending service life in exposed applications. Packaged in a 100-piece bulk pack for efficient inventory management, the JTEKD99 meets UNSPSC 31161528 specifications and is manufactured in the USA. Compatible with 14-16 gauge steel, 1/8-inch aluminum, and pressure-treated wood, this screw is a versatile fastening solution for roofing, HVAC, electrical panels, and structural connections.
