Overview

The NSi Industries JCB2 Carriage Bolt is a precision-engineered fastening solution for industrial, construction, and woodworking applications requiring secure metal-to-metal or wood-to-metal connections. Manufactured from cold-rolled steel with a uniform zinc plating for corrosion resistance, this bolt meets industrial-grade durability standards. The 1/4-20 UNC right-hand thread (20 threads per inch) ensures compatibility with standard nuts and tapped holes, while the 1-inch length provides adequate grip for typical fastening scenarios. The distinctive mushroom head design prevents over-tightening and provides a clean, finished appearance in exposed applications. Packaged in a 100-piece bulk jar for efficient inventory management, the JCB2 eliminates downtime by ensuring fasteners are always on hand. Ideal for HVAC systems, electrical panel assemblies, machinery frames, and structural woodwork, this bolt delivers consistent performance in environments where vibration resistance and long-term reliability are critical. The zinc plating offers 500+ hours of salt spray resistance per ASTM B117, making it suitable for outdoor and high-moisture applications. NSi Industries, a U.S.-based manufacturer, guarantees dimensional accuracy within ANSI B18.5 tolerances for seamless integration with standard hardware.
