- Optimized thread engagement with Class 2A UNC coarse threading provides faster assembly and reduced cross-threading risk
- Wide rounded head profile distributes clamping force evenly while preventing surface damage
- Full compliance with ASME B18.5 standards guarantees dimensional accuracy and interchangeability
- Environmental regulation compliance with RoHS 3 and REACH ensures safe use across regulated industries
Professional Applications & Engineering Value
This 316 stainless steel carriage bolt delivers exceptional engineering value through its corrosion-resistant properties and anti-rotation square neck design. The fully threaded UNC coarse thread pattern enables rapid installation in wood-to-metal and structural applications where vibration resistance is critical. The rounded head with wide bearing surface prevents pull-through in soft materials while maintaining aesthetic appeal. With Rockwell B55 hardness and 70,000 psi tensile strength, this fastener withstands heavy loads in marine, chemical processing, and construction environments where corrosion resistance and structural integrity are paramount. The square neck carriage bolt design eliminates the need for additional locking mechanisms, reducing assembly time and maintenance requirements.
Specification Summary & Compliance
Manufactured to ASME B18.5 specifications with Class 2A thread fit for consistent dimensional accuracy. Features 5/16"-18 UNC coarse threading with right-hand direction and 3/4" length. Fully compliant with RoHS 3 (2015/863/EU) and REACH (EC 1907/2006) environmental regulations. The inch system measurement ensures compatibility with North American industrial standards and replacement applications.
