Key Features & Benefits at a Glance
- Superior corrosion resistance with hot-dipped galvanized steel coating for long-lasting performance in harsh environments
- Prevents rotation during installation thanks to the integrated square neck design that locks securely into materials
- High tensile strength of 60,000 psi ensures reliable load-bearing capacity for demanding applications
- Easy installation and removal with fully threaded UNC coarse thread design and right-hand threading
- Wide rounded head profile provides excellent bearing surface and prevents pull-through in wood and metal
- Precision Class 2A thread fit guarantees consistent performance and compatibility with standard nuts
- Comprehensive regulatory compliance meets ASTM, ASME, RoHS 3, and REACH standards for quality and safety
Professional Applications & Engineering Value
These hot-dipped galvanized steel carriage bolts deliver exceptional durability in structural and construction applications where corrosion resistance and rotational stability are critical. The Grade 2 classification with 60,000 psi tensile strength and Rockwell B70 hardness ensures reliable performance in wood-to-wood and wood-to-metal connections, particularly in outdoor structures, fencing, and agricultural equipment. The fully threaded 5/16"-18 UNC coarse thread design combined with the square neck prevents spinning during installation, eliminating the need for additional locking mechanisms and reducing assembly time. This makes them ideal for industrial fastening applications requiring both strength and installation efficiency.
Specification Summary & Compliance
This carriage bolt features precision Class 2A thread fit with 5/16"-18 UNC coarse threading and right-hand direction. Manufactured to ASTM A307, ASTM A153, and ASME B18.5 specifications, ensuring dimensional accuracy and performance consistency. The product is fully compliant with RoHS 3 (2015/863/EU) and REACH (EC 1907/2006) environmental regulations, making it suitable for regulated industrial and construction applications worldwide.
