S-92356A716 1/2"-13 x 1 1/2" ASME B18.5 Carriage Bolts

Key Features & Benefits at a Glance

• Superior corrosion resistance with 18-8 stainless steel construction for long-lasting performance in harsh environments
• Exceptional load-bearing capacity with 70,000 psi tensile strength and Rockwell B55 hardness for heavy-duty applications
• Secure anti-rotation locking through the square neck design that prevents spinning during installation
• Reliable coarse threading with UNC 1/2"-13 pattern and Class 2A fit for quick assembly and vibration resistance
• Full-threaded convenience allowing maximum engagement depth and flexibility in material thickness
• Wide rounded head profile providing larger bearing surface to prevent pull-through in soft materials
• Regulatory compliance assurance meeting ASME B18.5 standards and environmental regulations (RoHS 3, REACH)

Professional Applications & Engineering Value

These 18-8 stainless steel carriage bolts deliver critical performance advantages for industrial fastening applications where corrosion resistance and structural integrity are paramount. The fully threaded UNC coarse thread design ensures rapid installation in wood-to-metal connections, structural framing, and heavy equipment assembly. The square neck mechanically locks into materials during tightening, eliminating rotation issues that plague standard bolts. With 70,000 psi tensile strength and Rockwell B55 hardness, these bolts maintain clamp force under extreme vibration and load conditions common in construction, transportation, and agricultural equipment. The 1/2"-13 thread size provides optimal strength-to-size ratio for demanding applications requiring reliable, permanent fastening solutions.
