Professional Applications & Engineering Value
Engineered for demanding applications where corrosion resistance is paramount, this silicon bronze carriage bolt delivers exceptional performance in marine hardware, dock construction, and coastal infrastructure. The combination of silicon bronze material and fully threaded UNC coarse threading provides superior resistance to saltwater corrosion while maintaining high tensile strength. The integrated square neck beneath the wide rounded head prevents rotation during tightening, eliminating the need for secondary locking mechanisms and reducing installation time. This ASME B18.5 compliant fastener is specifically designed for applications requiring reliable, long-term performance in corrosive environments where steel fasteners would rapidly deteriorate.
Specification Summary & Compliance
This 1/2"-13 UNC carriage bolt features Class 2A thread fit tolerance for consistent assembly performance and coarse threading for rapid installation. Manufactured in compliance with ASME B18.5 dimensional standards, the bolt ensures interchangeability and proper fitment. The product meets RoHS 3 (2015/863/EU) compliance for hazardous substance restrictions and REACH (EC 1907/2006) regulations for chemical safety, making it suitable for regulated industrial and marine applications worldwide.
