Overview

The NSi Industries JRM72 3/8-16 x 1-1/4 Round Head Combo Drive Machine Screw is a precision-engineered fastening solution designed for industrial machinery, equipment assembly, and structural applications. Manufactured in the USA by NSi Industries, this steel screw features a robust zinc plating for superior corrosion resistance, ensuring long-term durability in demanding environments. The combo drive design combines Phillips and flathead compatibility, allowing installers to use either driver type for faster, more flexible assembly without switching tools. With a 3/8-16 thread size and 1-1/4 inch length, this machine screw provides secure fastening for medium-duty applications where a low-profile round head is required. The zinc plating meets ASTM B633 standards for salt spray resistance, making it suitable for outdoor or high-moisture industrial settings. NSi Industries’ commitment to precision manufacturing ensures consistent threading and dimensional accuracy, reducing installation time and eliminating cross-threading issues. Ideal for OEMs, maintenance teams, and fabrication shops, the JRM72 delivers reliable performance in HVAC systems, electrical enclosures, and metal fabrication projects.
