Professional Applications & Engineering Value
Engineered specifically for demanding marine applications and harsh industrial environments, this silicon bronze carriage bolt delivers exceptional performance where corrosion resistance is critical. The fully threaded UNC coarse thread design combined with the square neck construction provides superior anti-rotation properties, eliminating the need for additional locking mechanisms in wood-to-metal and structural applications. The wide rounded head profile distributes clamping force evenly, preventing material damage while the 5/16"-18 thread size ensures reliable fastening in heavy-duty assemblies. Ideal for marine hardware, dock construction, and chemical processing equipment where saltwater corrosion resistance and long-term durability are essential engineering requirements.
Specification Summary & Compliance
This carriage bolt features precision Class 2A thread fit with UNC coarse threading (5/16"-18) and right-hand thread direction. Manufactured to ASME B18.5 specifications ensuring dimensional accuracy and mechanical performance. The product is fully compliant with RoHS 3 (2015/863/EU) and REACH (EC 1907/2006) environmental regulations, making it suitable for industrial applications requiring strict regulatory adherence.
