Professional Applications & Engineering Value

This 316 stainless steel carriage bolt delivers exceptional engineering value in corrosive environments where fastener integrity is critical. The square neck design effectively prevents rotation during torque application, eliminating the need for secondary locking mechanisms and reducing installation time. With 70,000 psi tensile strength and Rockwell B55 hardness, these carriage bolts maintain structural integrity under heavy loads while the UNC coarse threading ensures rapid assembly in wood, metal, and composite materials. The fully threaded configuration provides maximum engagement flexibility for varying material thicknesses, making these industrial carriage bolts ideal for construction, marine, chemical processing, and infrastructure applications where corrosion resistance and reliability are paramount.

Specification Summary & Compliance

This 5/8"-11 UNC carriage bolt features precise Class 2A thread fit tolerances and complies with ASME B18.5 dimensional standards. The manufacturing process adheres to strict quality controls ensuring consistent 0.625" diameter and proper square neck dimensions (0.34" length × 0.64" width). Regulatory compliance includes RoHS 3 (2015/863/EU) and REACH (EC 1907/2006) requirements, confirming the absence of restricted substances. The right-hand coarse threading and fully threaded design maintain industry-standard performance characteristics for reliable fastening solutions across multiple industrial sectors.
