Overview

The NSi Industries JRMB140 is a precision-engineered brass machine screw designed for applications requiring non-ferrous, corrosion-resistant fasteners. Manufactured in the USA, this #6-32 threaded screw features a 2.5-inch (2-1/2") length with a round head and slotted drive, ensuring compatibility with standard slotted screwdrivers for easy installation and removal. Each screw is made from solid brass, providing excellent resistance to corrosion, oxidation, and electrical conductivity—making it ideal for electrical, mechanical, and industrial assemblies where ferrous metals are unsuitable. Key specifications include a #6-32 thread size, compatible with pre-tapped or pre-drilled holes in brass, copper, or plastic components. The round head design distributes clamping force evenly while minimizing surface damage, and the slotted drive type allows for precise torque control during assembly. Packaged in quantities of 100, the JRMB140 is optimized for bulk applications in electronics, telecommunications, automotive wiring harnesses, and marine environments where brass fasteners are preferred for their durability and non-magnetic properties. Unlike stainless steel or plated steel screws, brass offers superior electrical conductivity and thermal stability, reducing the risk of galvanic corrosion when paired with dissimilar metals. The 2.5-inch length provides ample thread engagement for secure fastening in materials up to 2 inches thick, while the #6-32 thread ensures compatibility with standard hardware and fixtures. NSi Industries’ commitment to domestic manufacturing guarantees consistent quality and traceability, meeting industry standards for precision and reliability.
