Key Features & Benefits at a Glance
- Superior anti-rotation performance with a square neck design that prevents spinning during installation and use
- Enhanced corrosion resistance through zinc-plated steel construction for extended service life in harsh environments
- Reliable load-bearing capacity with Grade 2 strength rating and 60,000 psi tensile strength for demanding applications
- Quick and easy installation thanks to coarse UNC threading and fully threaded design for faster assembly
- Secure fastening in wood and metal with wide rounded head distributing load evenly and preventing pull-through
- Consistent dimensional accuracy with Class 2A thread fit ensuring proper engagement and reduced cross-threading risks
- Long-term durability supported by Rockwell B70 hardness for resistance to wear and deformation
Professional Applications & Engineering Value
This zinc-plated steel carriage bolt delivers exceptional engineering value in structural and construction applications where vibration resistance and security are paramount. The square neck design mechanically locks into materials, eliminating rotation during torque application - a critical advantage in wood-to-metal connections and framing systems. The coarse UNC threading provides superior holding power in softer materials while resisting loosening under dynamic loads. With Grade 2 strength classification and 60,000 psi tensile strength, this fully threaded fastener maintains integrity in heavy-load scenarios from industrial equipment to agricultural machinery. The zinc plating creates a sacrificial barrier against environmental elements, making it ideal for outdoor structures, trailer assemblies, and construction projects requiring long-term reliability without frequent maintenance.
Specification Summary & Compliance
This carriage bolt features precision 7/16"-14 UNC coarse threads with Class 2A fit for consistent dimensional accuracy and proper engagement. Manufactured to meet ASTM A307, SAE J429, and ASME B18.5 specifications for quality assurance. The product is RoHS 3 (2015/863/EU) compliant and contains no restricted hazardous substances, ensuring environmental responsibility while maintaining mechanical performance standards for industrial applications.
