S-92356A552 1/4"-20 x 2 1/2" ASME B18.5 Carriage Bolts

Key Features & Benefits at a Glance

• Superior corrosion resistance with 18-8 Stainless Steel construction, ideal for harsh environments and outdoor applications
• Enhanced anti-rotation security thanks to the square neck design that prevents spinning during installation and use
• High tensile strength of 70,000 psi ensures reliable performance under heavy loads and mechanical stress
• Wide rounded head profile provides larger bearing surface for better load distribution and reduced surface damage
• Precision Class 2A thread fit guarantees smooth assembly and consistent fastening performance
• Full threading along the 2-1/2" length offers maximum engagement flexibility for various material thicknesses
• Compliance with ASME B18.5 standards ensures dimensional accuracy and interchangeability with other compliant components

Professional Applications & Engineering Value

This 1/4"-20 UNC coarse thread carriage bolt delivers exceptional engineering value in demanding industrial applications where vibration resistance and long-term reliability are critical. The combination of 18-8 Stainless Steel material with Rockwell B55 hardness provides excellent corrosion resistance while maintaining sufficient ductility for shock absorption. The square neck design effectively prevents rotation during torque application, eliminating the need for secondary locking mechanisms in wood-to-metal connections, structural framing, and heavy equipment assembly. The fully threaded configuration with Class 2A fit ensures consistent clamping force distribution across the entire fastener length, making it particularly valuable in agricultural machinery, transportation equipment, and construction applications where joint integrity cannot be compromised.
