Overview

The NSi Industries JRMB48 Brass Machine Screw (#10-32 x 3/4", round head, slotted drive) is a precision-engineered brass fastener designed for industrial, electrical, and mechanical assemblies requiring corrosion resistance and electrical conductivity. Manufactured from solid brass, this screw delivers superior durability in both indoor and outdoor environments, resisting oxidation and chemical degradation better than standard steel fasteners. The #10-32 thread size ensures compatibility with pre-tapped holes in brass, aluminum, or steel components, while the 3/4-inch length provides optimal grip in applications where thread engagement is critical. The round head offers a smooth, flush surface finish that minimizes snagging or interference in moving parts, and the slotted drive type allows for easy installation using standard flathead screwdrivers or powered drivers. Each 100-piece pack provides bulk quantity for large projects, reducing procurement time and inventory complexity. Typical applications include electrical panel assemblies, telecommunications equipment, marine hardware, and precision machinery where non-magnetic properties and electrical conductivity are required. Unlike zinc-plated screws, brass fasteners like the JRMB48 do not require additional coating for corrosion protection in moist or chemically aggressive environments, making them ideal for plumbing fixtures, outdoor electrical enclosures, and food processing equipment. The screw’s UNSPSC code 31161504 classifies it under machine screws, brass, and meets NSi Industries’ quality standards for dimensional accuracy and material purity. For projects requiring non-sparking properties or compliance with electrical conductivity requirements, the JRMB48 is a reliable choice where stainless steel or plated fasteners may fall short.
