S-92356A550 1/4"-20 x 2" ASME B18.5 Carriage Bolts

Key Features & Benefits at a Glance

• Superior corrosion resistance with 18-8 stainless steel construction, ideal for harsh industrial environments
• Exceptional mechanical strength with 70,000 psi tensile strength and Rockwell B55 hardness for reliable load-bearing performance
• Effective anti-rotation security thanks to the integrated square neck design that prevents spinning during installation
• Wide compatibility and easy installation with fully threaded UNC coarse spacing and Class 2A thread fit
• Enhanced durability and longevity from the rounded carriage head profile that distributes stress evenly
• Regulatory compliance assurance meeting ASME B18.5 standards and environmental directives (RoHS 3, REACH)
• Versatile industrial application with 2" length and right-hand threading for efficient assembly in various settings

Professional Applications & Engineering Value

This 18-8 stainless steel carriage bolt is engineered to address critical challenges in industrial fastening, such as vibration-induced loosening and environmental degradation. The square neck securely locks into materials, eliminating rotation during torque application—a common pain point in wood-to-metal and structural assemblies. Its fully threaded UNC coarse spacing ensures rapid installation and high pull-out resistance, while the corrosion-resistant material withstands moisture, chemicals, and temperature variations. Ideal for construction, machinery, and transportation equipment, this bolt delivers consistent performance under 70,000 psi tensile loads, reducing maintenance needs and downtime in demanding applications.

Specification Summary & Compliance

This carriage bolt adheres to Class 2A thread fit and UNC thread standards with a 1/4"-20 coarse spacing for precise engagement. Manufactured in compliance with ASME B18.5 specifications, it ensures dimensional accuracy and interoperability. The product is verified as RoHS 3 (2015/863/EU) Compliant and REACH (EC 1907/2006) Compliant, confirming the absence of restricted hazardous substances and supporting sustainable procurement practices.
