Description

When you need a bolt that can handle serious torque and won’t let you down in the field, this 5/8 x 8 inch Grade 5 hex bolt is what you reach for. Whether you’re mounting a cultivator shank, securing a heavy attachment, or fixing a piece of equipment that needs to stay put under load, this bolt gives you the strength and reliability you need when the work can’t wait.

What You’re Getting

Grade 5 steel construction that handles high-stress applications without stretching or breaking
Zinc plating resists rust and corrosion even in wet field conditions
UNC (coarse) threads bite deep and hold tight in standard farm equipment holes
8-inch length reaches through thick mounting brackets and multiple layers of steel
5/8-inch diameter provides serious holding power for heavy-duty connections

Built for Real Farm Work

This bolt is sized for the heavy stuff—think three-point hitch pins, cultivator mounting points, loader brackets, and anywhere you need a fastener that won’t quit. The 8-inch length gives you plenty of thread engagement even when you’re going through thick plates or multiple pieces of steel.

Made to Last

Grade 5 steel means this bolt can handle about 120,000 PSI of tensile strength—that’s serious holding power for farm equipment that takes a beating. The zinc coating keeps rust at bay so you won’t be fighting seized bolts down the road.

Good to Know

Always use a properly sized wrench to avoid rounding the hex head, and don’t forget to use washers under both the head and nut to distribute the load. A little anti-seize on the threads makes future removal much easier if you’re working in muddy or corrosive conditions.
