S-93548A117 10-24 x 1 1/4" ASTM A307, SAE J429, ASME B18.5 Carriage Bolts

Key Features & Benefits at a Glance

• Enhanced corrosion resistance with zinc-plated steel construction, extending service life in demanding industrial environments
• Superior anti-rotation performance due to integrated square neck design that prevents spinning during installation and operation
• High tensile strength of 60,000 PSI (Grade 2) ensures reliable load-bearing capacity for structural applications
• Excellent durability with Rockwell B70 hardness, maintaining integrity under repeated stress and vibration
• Easy installation and removal with UNC coarse threading and Class 2A thread fit for smooth engagement
• Versatile compatibility with fully threaded right-hand design accommodating various material thicknesses
• Regulatory compliance assurance meeting ASTM A307, SAE J429, and ASME B18.5 standards for quality and safety

Professional Applications & Engineering Value

This Grade 2 zinc-plated steel carriage bolt delivers critical engineering solutions for industrial fastening challenges. The square neck design mechanically locks into materials, eliminating rotation during torque application - particularly valuable in wood-to-metal connections and structural framing where vibration resistance is essential. The UNC coarse threading provides rapid installation in soft materials while maintaining strong holding power. With 60,000 PSI tensile strength and Rockwell B70 hardness, these carriage bolts withstand substantial shear and tensile loads in construction equipment, agricultural machinery, and transportation applications. The zinc plating offers sacrificial corrosion protection, making these fasteners suitable for both indoor and outdoor environments where moisture exposure occurs.

Specification Summary & Compliance

This 10-24 carriage bolt features precise Class 2A thread fit tolerances with UNC coarse thread specification, ensuring consistent performance across applications. Manufacturing complies with ASTM A307 for low carbon steel fasteners, SAE J429 for mechanical properties, and ASME B18.5 for dimensional standards. Environmental compliance is verified through RoHS 3 (2015/863/EU) and REACH (EC 1907/2006) certifications, confirming restriction of hazardous substances in industrial applications.
