Overview

The NSI Industries JRM123 is a 3/8-16 x 2-1/2 inch round head combo drive machine screw made from durable carbon steel with a zinc coating for corrosion resistance. This screw features a combo drive head compatible with both Phillips and slotted screwdrivers, eliminating the need for tool changes during installation. The 3/8-16 thread size ensures compatibility with standard industrial components, while the 2-1/2 inch length provides secure engagement in pre-tapped holes or with nuts. Manufactured in the USA to meet industrial performance requirements, the JRM123 delivers reliable fastening in machinery assembly, automotive components, and construction projects. The zinc plating provides reliable protection against corrosion in harsh environments, making it ideal for heavy-duty applications where durability and long-term performance are critical. The combo drive design reduces installation time by allowing installers to use either driver type without switching tools.
