Professional Applications & Engineering Value
Engineered for demanding environments where corrosion resistance is critical, these silicon bronze carriage bolts provide exceptional durability in marine applications, chemical processing plants, and coastal infrastructure. The square neck design effectively prevents rotation during tightening, eliminating the need for secondary locking mechanisms and reducing installation time. The 3/8"-16 UNC coarse threading ensures reliable performance in high-vibration applications while the fully threaded configuration offers maximum engagement strength. These carriage bolts maintain structural integrity in saltwater exposure and harsh weather conditions, making them ideal for dock hardware, marine fittings, and outdoor industrial equipment where traditional steel fasteners would rapidly deteriorate.
Specification Summary & Compliance
This carriage bolt features precision Class 2A thread fit with 3/8"-16 UNC coarse threading and right-hand thread direction. Manufactured to ASME B18.5 standards with a 0.844" head diameter and square neck measuring 0.39" width. The product is fully compliant with RoHS 3 (2015/863/EU) and REACH (EC 1907/2006) environmental regulations, ensuring safe use across industrial and marine applications.
