Product Description

The 5/16-18x5-3/4 Bolts feature a 5/16-inch diameter with 5-3/4-inch length and 5/16-18 UNC coarse thread pattern compliant with ANSI/ASME standards. These 5/16-18 Coarse Thread Bolts provide a tensile strength of 120,000 PSI (Grade 8) and are crafted from zinc-plated carbon steel for corrosion resistance. Designed for industrial fastening in construction, automotive, and machinery assembly applications, they operate effectively in environments ranging from -40°F to 250°F (-40°C to 121°C). The 5/16-18 UNC Threaded Rod configuration enables direct integration with nuts, plates, or structural components requiring secure coarse-thread engagement. Key advantages include high shear resistance and vibration tolerance, though prolonged exposure to saltwater may reduce coating durability. Compatible with standard 1/2-inch wrenches, these bolts deliver optimal performance in heavy-load scenarios while maintaining precise thread alignment.
