Professional Applications & Engineering Value

This 316 stainless steel carriage bolt delivers exceptional engineering value through its combination of marine-grade corrosion resistance and high-strength performance. The square neck design effectively solves common rotation issues during installation, making it ideal for wood-to-metal applications where anti-rotation is critical. The fully threaded UNC coarse thread configuration ensures rapid installation in structural applications while maintaining 70,000 psi tensile strength for heavy-duty fastening requirements. Particularly valuable in marine environments, chemical processing facilities, and outdoor infrastructure, this bolt's wide rounded head distributes clamping force evenly, preventing surface damage to connected materials. The coarse thread pitch provides superior performance in softer materials and applications subject to vibration, making it a versatile solution for industrial maintenance, construction, and equipment manufacturing.
