Description
When you’re working on equipment that can’t afford to come apart, this Grade 8 hex bolt delivers the strength you need. Whether you’re rebuilding a three-point hitch, mounting a hydraulic pump, or fixing that bracket that’s been rattling loose, this bolt won’t let you down when the work gets tough.
What You’re Getting
- Grade 8 strength rating—about 50% stronger than Grade 5 bolts for critical connections
- Zinc plating fights off rust and corrosion so it won’t seize up on you later
- UNC thread pitch for reliable fit with standard nuts and threaded holes
- 1-inch length works great for lighter assemblies and thin-wall applications
Built for Real Farm Work
This 5/16-inch bolt size is perfect for medium-duty connections on tractors, implements, and shop-built repairs. You’ll find this size holding together everything from gauge wheels and seed meters to hydraulic fittings and electrical brackets. The 1-inch length is just right when you need a secure connection without extra bolt sticking out to catch on things.
Made to Last
Grade 8 bolts are heat-treated to handle serious loads and vibration without stretching or breaking. The zinc coating helps them stand up to moisture, fertilizer spray, and road salt—so they’ll still come apart years later when you need to service something. These aren’t hardware store bolts that’ll snap when you really need them.
Good to Know
Always use a flat washer under the head to spread the load properly and prevent the bolt from pulling through. A 1/2-inch wrench fits the hex head perfectly. If you’re replacing a rusted bolt, clean out the threads first—a wire brush or thread chaser makes the job easier and ensures a proper fit.
