Overview

The Minerallac 78808J is a #8-18 x 1/2" self-drilling (TEK) sheet metal screw designed for direct metal-to-metal fastening without pre-drilling. Featuring a hex washer head (0.247" width, 0.103" height) and #2 drill point, this zinc-plated steel screw eliminates the need for separate drilling and tapping operations, reducing installation time and labor costs. The Type-BSD thread (18 threads per inch) ensures secure engagement in sheet metal applications, while the zinc plating provides corrosion resistance for indoor and protected outdoor environments. Engineered for HVAC ductwork, electrical enclosures, and general metal fabrication, the 78808J delivers reliable performance in applications requiring a flush or low-profile fastener. The hex washer head distributes clamping force evenly, minimizing pull-through risk in thin-gauge metals. Compatible with standard #2 driver bits, these screws are packaged in jars of 100 units with master cartons of 1200 for bulk handling efficiency. The 1/2" length provides optimal thread engagement for typical sheet metal thicknesses up to 16 gauge. Key specifications: - Size: #8-18 x 1/2" - Head type: Hex washer head (silver finish) - Drill point: #2 - Material: Steel with zinc plating - Thread type: Type-BSD - Thread size: 18 TPI - Head dimensions: 0.247" width, 0.103" height - Packaging: 100 per jar, 1200 per master carton - UPC: 08593708212 Ideal for quick, tool-driven installations in HVAC, electrical, and light fabrication projects where speed and reliability are critical.
