Key Features & Benefits at a Glance
- Superior corrosion resistance with 18-8 stainless steel construction, ideal for harsh industrial environments
- Exceptional anti-rotation performance thanks to the integrated square neck that prevents spinning during installation
- High tensile strength of 70,000 psi ensures reliable performance under heavy loads and stress
- Optimized thread engagement with partial threading and Class 2A fit for secure fastening and easier alignment
- Wide rounded head design provides enhanced bearing surface and prevents pull-through in soft materials
- Coarse UNC thread pattern enables quick installation and reduced cross-threading risk in field applications
- Rockwell B55 hardness maintains structural integrity and resists deformation during repeated use
Professional Applications & Engineering Value
This heavy-duty carriage bolt delivers critical engineering solutions where vibration resistance and security are paramount. The 18-8 stainless steel composition provides excellent corrosion resistance for outdoor equipment, marine applications, and food processing facilities. The square neck design eliminates the need for secondary locking mechanisms by positively engaging with the material, preventing rotation during torque application. With partial threading, the bolt maintains maximum strength in the shank while providing sufficient thread engagement. The coarse UNC thread ensures reliable performance in wood, structural steel, and other industrial materials where quick assembly and disassembly are required. These features make it ideal for construction, transportation equipment, and agricultural machinery where anti-rotation performance and durability are essential.
Specification Summary & Compliance
This carriage bolt features precision Class 2A thread fit with 3/8"-16 UNC coarse threading and right-hand direction. Manufacturing complies with ASME B18.5 standards for dimensional accuracy and performance. The product meets RoHS 3 (2015/863/EU) compliance for hazardous substance restrictions and REACH (EC 1907/2006) regulations for chemical safety. Critical dimensions include 12" length, 0.844" head diameter, and 0.39" square neck width, ensuring consistent performance across industrial applications.
