Key Features & Benefits at a Glance
- Superior corrosion resistance with 316 stainless steel construction, ideal for harsh industrial and marine environments
- Enhanced anti-rotation performance due to the square neck design that prevents spinning during installation
- High load-bearing capacity with 70,000 psi tensile strength and Rockwell B55 hardness for demanding applications
- Secure fastening in wood and metal using the coarse 5/8"-11 UNC thread pattern with Class 2A fit
- Quick installation and adjustment with partially threaded design and right-hand threading
- Reliable compliance meeting ASME B18.5 standards and environmental regulations including RoHS 3 and REACH
- Optimized for heavy-duty use featuring a wide, rounded carriage head for distributed load and 7" length for deep material penetration
Professional Applications & Engineering Value
This 316 stainless steel carriage bolt is engineered to address critical challenges in industrial fastening, such as corrosion-induced failure and joint instability. The square neck securely locks into materials, eliminating rotation during torque application and reducing assembly time. With a coarse UNC thread and partial threading, it provides strong grip in wood, structural steel, and machinery while resisting vibration loosening. The rounded head profile distributes pressure evenly, minimizing surface damage. Ideal for construction, transportation, and marine equipment, this bolt ensures long-term reliability in corrosive or high-stress environments, supported by its 70,000 psi tensile strength and compliant manufacturing.
Specification Summary & Compliance
This carriage bolt adheres to ASME B18.5 dimensional standards with a Class 2A thread fit for consistent engagement. It features a 5/8"-11 UNC coarse thread, right-hand direction, and partial threading (minimum 1" thread length). The product is fully compliant with RoHS 3 (2015/863/EU) and REACH (EC 1907/2006) regulations, ensuring environmental safety and material integrity.
