S-93548A911 3/4"-10 x 6" ASTM A307, SAE J429, ASME B18.5 Carriage Bolts

Key Features & Benefits at a Glance

• Superior anti-rotation performance thanks to the integrated square neck design that prevents spinning during installation and under load
• Exceptional durability and corrosion resistance provided by the zinc-plated steel finish, ideal for demanding industrial and construction environments
• High tensile strength of 60,000 psi (Grade 2) ensures reliable performance in heavy-duty applications and structural connections
• Wide, rounded head profile distributes clamping force effectively and provides a finished appearance while reducing surface damage
• Coarse UNC threading (3/4"-10) with Class 2A fit allows for faster assembly and better performance in materials like wood and soft metals
• Full threading along the 6-inch length offers maximum flexibility for use with a wide range of material thicknesses and nut positions
• Rockwell B70 hardness provides excellent resistance to wear and deformation under stress, extending the fastener's service life

Professional Applications & Engineering Value

This heavy-duty carriage bolt is engineered to solve critical challenges in construction, agricultural equipment, and structural framing where vibration and load can cause standard fasteners to fail. The zinc-plated steel construction combats corrosion in outdoor and high-moisture environments, while the square neck design securely locks into materials to prevent rotation during torque application—eliminating the need for secondary locking mechanisms. The coarse UNC thread ensures quick installation and superior grip in wood and soft substrates, making these Grade 2 carriage bolts ideal for timber structures, trailer beds, and machinery assemblies where anti-rotation performance and 60,000 psi tensile strength are paramount for long-term structural integrity.
