- Superior corrosion resistance provided by zinc-plated steel construction, extending service life in industrial environments.
- Secure anti-rotation installation enabled by the knurled neck design that prevents spinning during tightening.
- Optimized thread engagement through UNC coarse threading and Class 2A fit, ensuring consistent fastening and vibration resistance.
- Enhanced durability from Rockwell C25 hardness, maintaining structural integrity under repeated stress.
- Broad compatibility with a rounded carriage head and partially threaded shank for versatile use across machinery and structural assemblies.
- Regulatory compliance meeting SAE J429 standards, RoHS 3, and REACH for safe, sustainable industrial use.
Professional Applications & Engineering Value
This Grade 5 zinc-plated steel carriage bolt delivers critical reliability in heavy-duty fastening scenarios. Its rounded head and knurled neck work in tandem to eliminate rotation during installation, a common issue in wood-to-metal or structural connections. The UNC coarse thread and Class 2A fit provide rapid assembly and robust holding power, reducing the risk of loosening under vibration. With a tensile strength of 120,000 psi and Rockwell C25 hardness, it withstands high-stress conditions in construction, agricultural equipment, and transportation frameworks. The zinc plating offers a protective barrier against rust, ensuring long-term performance even in humid or outdoor settings, while compliance with SAE J429 guarantees consistent quality for engineering and maintenance teams.
Specification Summary & Compliance
This carriage bolt adheres to precise dimensional standards, including a 5/16"-18 UNC coarse thread with Class 2A tolerance for accurate fit. It is manufactured under SAE J429 specifications, ensuring mechanical properties like tensile strength and hardness are consistently met. The product is fully compliant with RoHS 3 (2015/863/EU) and REACH (EC 1907/2006) regulations, confirming the absence of restricted hazardous substances and supporting environmentally responsible procurement.
