S-93548A113 10-24 x 1" ASTM A307, SAE J429, ASME B18.5 Carriage Bolts

Key Features & Benefits at a Glance

• Superior corrosion resistance with zinc-plated steel construction for extended service life in demanding environments
• Reliable anti-rotation performance through integrated square neck design that prevents spinning during installation
• Excellent tensile strength with Grade 2 rating and 60000 psi capacity for heavy-duty applications
• Optimized thread engagement with UNC coarse threading that provides faster assembly and reduced cross-threading risk
• Consistent dimensional accuracy with Class 2A thread fit ensuring proper mating with nuts and components
• Enhanced durability with Rockwell B70 hardness that maintains structural integrity under stress
• Wide compatibility with rounded carriage head profile that distributes load evenly across surfaces

Professional Applications & Engineering Value

This 10-24 UNC carriage bolt delivers exceptional engineering value through its zinc-plated steel construction and specialized design features. The square neck provides critical anti-rotation capability, eliminating the need for additional locking mechanisms in wood-to-metal and structural applications. The fully threaded configuration with right-hand coarse threading ensures rapid installation in timber framing, agricultural equipment, and construction assemblies where vibration resistance is paramount. The rounded head profile with wide bearing surface prevents pull-through in softer materials while maintaining a finished appearance. These industrial carriage bolts solve common fastening challenges by combining secure locking action with the corrosion protection needed for long-term structural integrity in outdoor and high-moisture environments.
