Professional Applications & Engineering Value
These silicon bronze carriage bolts deliver exceptional value in demanding environments where corrosion resistance is critical. The square neck design effectively prevents rotation during tightening, eliminating the need for secondary locking mechanisms and reducing installation time. The fully threaded UNC coarse thread configuration ensures rapid assembly and reliable performance in wood, composite materials, and softer metals. Engineered specifically for marine applications, industrial settings, and outdoor structures, these bolts maintain integrity in saltwater exposure, high humidity, and harsh weather conditions. The combination of silicon bronze material properties and ASME B18.5 compliance provides engineers with a trusted solution for long-term structural integrity in corrosive environments.
Specification Summary & Compliance
This 5/16"-18 UNC carriage bolt features Class 2A thread fit tolerance and coarse thread spacing for reliable performance. Manufactured in compliance with ASME B18.5 standards for dimensional accuracy and mechanical properties. The product meets RoHS 3 (2015/863/EU) compliance and REACH (EC 1907/2006) environmental regulations, ensuring safe use in various industrial applications. The square neck measures 0.19" in length and 0.32" in width, providing secure anti-rotation performance when installed in corresponding square holes.
