Whether you’re mounting a heavy implement to your three-point hitch, securing loader brackets, or building custom equipment in the shop, this bolt delivers the strength and reliability that heavy farm work demands.
What You’re Getting
- Grade 8 tensile strength handles extreme loads without stretching or breaking

Built for Real Farm Work
This bolt size is perfect for the heaviest connections on your equipment. You’ll use these when mounting big implements, securing structural components on combines, attaching loader arms, or building heavy-duty shop projects. The 1-inch diameter and 4-inch length handle everything from thick steel fabrication to multi-piece assemblies that need serious holding power.
Made to Last
Grade 8 bolts are the strongest fasteners you can buy for general farm use—about twice as strong as hardware store bolts. The zinc coating keeps them from rusting out, even when they’re exposed to fertilizer, road salt, and weather. These bolts are built to stay tight and strong season after season.
Installation Notes
Always use flat washers under both the head and nut to distribute the load properly. If you’re replacing old bolts, clean out the threads first and consider using a little anti-seize compound to make future removal easier. This bolt requires a 1-1/2 inch wrench or socket.
