Overview

The NSi Industries JCB23 Carriage Bolt is a precision-engineered steel fastener designed for heavy-duty wood-to-metal and metal-to-metal fastening in industrial, construction, and manufacturing applications. Constructed from Grade 2 steel with a uniform zinc-plated finish, this bolt delivers corrosion resistance and long-term durability in exposed or high-moisture environments. The 3/8-16 right-hand thread (coarse series) ensures rapid installation with standard tools, while the low-profile mushroom head provides a clean, secure surface that resists loosening under vibration. With a total length of 1.5 inches and a threaded length of 1.25 inches, the JCB23 accommodates thick material stacks without bottoming out. Supplied in a 100-piece bulk pack, it supports high-volume procurement for production lines, job sites, and maintenance operations. Compatible with standard 3/8-inch washers and nuts, this bolt meets general-purpose industrial standards and is ideal for securing machinery bases, conveyor systems, wooden structures, and metal frameworks. The zinc plating provides a minimum of 500 hours of salt spray resistance per ASTM B117, ensuring reliable performance in outdoor and corrosive settings. NSi Industries, a U.S.-based manufacturer, guarantees dimensional accuracy and thread consistency for tool-free installation and long service life.
