Overview

The NSi Industries JCB33G Galvanized Mushroom Head Carriage Bolt is a precision-engineered fastening solution for industrial and construction applications requiring corrosion resistance and low-profile installation. This bolt features a 1/2-13 right-hand thread with a 2-inch length, fully threaded for maximum grip and load distribution. The galvanized finish provides superior protection against rust and corrosion in outdoor or high-moisture environments, extending service life in framing, mechanical assemblies, and structural connections. Key specifications include a mushroom head design that resists pull-through and eliminates the need for separate washers, reducing installation time. Each pack contains 25 bolts, manufactured in the US to meet stringent quality standards for mechanical assemblies, woodworking, and general construction. The 1/2-13 thread pitch ensures compatibility with standard nuts and pre-tapped holes, while the galvanized coating meets ASTM A153 standards for outdoor durability. Ideal for applications such as decking, fencing, HVAC mounting, and light structural framing where a smooth finish and corrosion resistance are critical. The JCB33G is not recommended for high-stress applications requiring Grade 5 or higher mechanical properties. For heavy-duty load-bearing connections, consider Grade 5 or stainless steel alternatives. NSi Industries’ US-based manufacturing ensures consistent thread tolerances and dimensional accuracy for reliable performance in demanding environments.
