Overview

The NSi Industries JDS186 tapping screw is a 12-gauge, 1/2-inch long indented hex head (5/16-inch drive) fastener designed for metal-to-metal applications. Made from durable zinc-plated steel, it provides corrosion resistance in industrial environments while eliminating the need for pre-tapped holes. The indented hex head ensures secure tool engagement for high torque applications, and the slot drive accepts standard flathead screwdrivers. This self-tapping screw features sharp threads for clean penetration into steel, aluminum, or other metals without additional drilling or tapping. Ideal for assembly lines, machinery fabrication, HVAC systems, and construction where reliable, vibration-resistant fasteners are required. The zinc plating meets ASTM B633 standards for salt spray resistance exceeding 200 hours. Compatible with automated screwdriving systems and manual tools, the JDS186 reduces installation time by up to 40% compared to traditional bolts and nuts. NSi Industries, a US-based manufacturer, produces this fastener to UNSPSC 31161506 specifications.
