Overview

The NSI Industries JRM103SLT is a precision-engineered 1/4-20 x 1-1/2 round head slot machine screw designed for industrial fastening applications. Manufactured from durable low-carbon steel, this fastener features a zinc coating for reliable corrosion resistance in demanding environments. The 1.5-inch (38.1 mm) length and 1/4-20 thread size ensure secure engagement in machinery assembly, equipment mounting, and general industrial tasks. The round head incorporates a standard slot drive, compatible with common flat-blade screwdrivers for easy installation and removal. Zinc plating provides effective protection against rust and wear, extending component lifespan in operational settings. This machine screw meets industrial quality standards and is proudly produced in the USA. Its precise thread engagement and long-term reliability make it ideal for applications requiring dependable fastening solutions, including assembly lines, manufacturing equipment, and maintenance operations. The 1/4-20 thread pitch ensures compatibility with standard threaded holes, while the zinc finish offers uniform coverage for consistent performance in both indoor and outdoor environments. NSI Industries specifies this screw for use in high-stress applications where vibration resistance and secure fastening are critical.
