Professional Applications & Engineering Value

This 316 stainless steel carriage bolt delivers exceptional engineering value where corrosion resistance and vibration management are critical. The square neck design mechanically locks into assembled materials, preventing rotation during torque application and eliminating the need for secondary locking mechanisms. With fully threaded UNC coarse threading, it accommodates varying material thicknesses while providing superior resistance to vibration loosening in heavy machinery, structural steel connections, and marine equipment. The Rockwell B55 hardness and 70,000 psi tensile strength ensure durability under dynamic loads, making it ideal for bridge construction, chemical processing equipment, and offshore installations where failure is not an option. Its rounded head profile enhances safety while maintaining the structural integrity required in high-stress applications.

Specification Summary & Compliance

This carriage bolt maintains Class 2A thread fit tolerance per UNC standards with 5/8"-11 coarse threading and 0.625" diameter. Manufacturing complies with ASME B18.5 specifications for dimensional accuracy and performance. The product is RoHS 3 (2015/863/EU) compliant and meets REACH (EC 1907/2006) requirements regarding substance restrictions, ensuring environmental responsibility in industrial supply chains.
