Overview

The NSi Industries JRMP52 is a 12-24 x 1-1/2 inch round head Phillips machine screw with a zinc-plated finish, designed for industrial fastening applications requiring corrosion resistance and secure drive engagement. This machine screw features a #12 thread size with 24 threads per inch, ensuring compatibility with standard tapped holes and nuts. The 1.5-inch length provides sufficient grip for metal-to-metal joints, machinery assembly, and equipment mounting. The round head design distributes clamping force evenly while maintaining a low-profile finish, ideal for applications where protrusion must be minimized. The Phillips drive recess allows for efficient installation using standard #2 Phillips drivers, reducing cam-out risk during tightening. Zinc plating offers basic corrosion protection, making this screw suitable for indoor industrial environments, HVAC systems, electrical enclosures, and light structural assemblies. NSi Industries, a U.S.-based manufacturer, produces this screw to commercial-grade standards, ensuring consistent threading and dimensional accuracy. This fastener is commonly used in conjunction with washers or nuts for secure joint assembly in manufacturing, construction, and maintenance operations.
