Overview

The NSi Industries JTEKD30 is a #12 size self-drilling and tapping screw engineered for metal-to-metal fastening in industrial and construction applications. Constructed from durable steel with a zinc chromate finish, this screw delivers reliable corrosion resistance in exposed environments. The 3-inch length and 5/16-inch hex washer head provide secure engagement and load distribution, while the hex drive type ensures compatibility with standard hex drivers for efficient installation. Key specifications include a #3 drill point for direct penetration into metal substrates without pre-drilling, eliminating secondary operations and reducing labor time. The indented hex washer head design enhances pull-out resistance and prevents over-tightening, making it ideal for structural connections, HVAC ductwork, electrical enclosures, and sheet metal assemblies. Each pack contains 100 screws, offering a practical bulk quantity for high-volume projects. This self-drilling screw is optimized for use with steel substrates up to specified thicknesses, providing a fast and cost-effective alternative to traditional bolts or rivets. The zinc chromate finish meets standard industrial corrosion protection requirements, ensuring long-term performance in indoor and outdoor applications. Compatible with common hex tools, the JTEKD30 simplifies assembly workflows while maintaining high holding strength. For applications requiring stainless steel or alternative finishes, refer to NSi’s JTEKD series variants.
