Professional Applications & Engineering Value
This 316 stainless steel carriage bolt is engineered to address critical challenges in corrosive and high-stress environments. Its marine-grade material resists pitting and rust, making it ideal for offshore structures, chemical processing equipment, and food industry machinery where moisture and chemicals are prevalent. The square neck design locks securely into materials, eliminating rotation during torque application and preventing loosening under vibration—a common failure point in dynamic industrial settings. With fully threaded UNC coarse threading and Class 2A thread fit, it ensures rapid assembly and consistent clamping force, reducing installation time and maintenance needs in construction, transportation, and heavy machinery applications.
Specification Summary & Compliance
This carriage bolt features precise Class 2A thread fit and adheres to UNC coarse thread standards with a 3/8"-16 thread size. Manufactured in compliance with ASME B18.5 specifications, it ensures dimensional accuracy and reliability. The product is also RoHS 3 (2015/863/EU) Compliant and REACH (EC 1907/2006) Compliant, meeting stringent environmental and safety regulations for industrial use.
