Key Features & Benefits at a Glance
- Superior corrosion resistance with 316 stainless steel construction, ideal for harsh environments and outdoor applications
- Enhanced anti-rotation performance due to the square neck design, preventing bolt spinning during installation and use
- High tensile strength of 70,000 psi ensures reliable load-bearing capacity in demanding structural and construction applications
- Excellent durability with Rockwell B55 hardness, providing resistance to wear and deformation under stress
- Wide rounded head profile distributes clamping force effectively and reduces surface damage
- Coarse UNC threading allows for faster installation and better performance in softer materials or where debris is present
- Full threading along the 4" length offers versatile fastening options and adjustability in various material thicknesses
Professional Applications & Engineering Value
This 316 stainless steel carriage bolt is engineered to solve critical challenges in industrial and construction settings where corrosion resistance and vibration resistance are paramount. The combination of a wide rounded head and square neck creates a secure, non-rotating fastening solution that eliminates the need for additional locking mechanisms. The coarse UNC thread ensures quick assembly even in challenging conditions, while the fully threaded design provides consistent clamping force across various material thicknesses. Ideal for structural connections, machinery assembly, and marine applications, this bolt delivers long-term reliability where exposure to moisture, chemicals, and stress would compromise ordinary fasteners.
Specification Summary & Compliance
This carriage bolt features precision 3/4"-10 UNC coarse threads with Class 2A thread fit for consistent engagement and ease of assembly. Manufactured in compliance with ASME B18.5 standards for dimensional accuracy and performance. The product meets RoHS 3 (2015/863/EU) and REACH (EC 1907/2006) environmental compliance requirements, ensuring safe use in regulated industries and international markets.
