When you’re mounting implements, securing tool boxes, or building custom brackets on your farm equipment, you need hardware that won’t let you down. This heavy-duty square U-bolt gives you the strength and reliability to handle serious mounting jobs around the farm, from attaching cultivator shanks to securing loader accessories.
What You’re Getting
- 5/8-inch square design provides superior clamping force compared to round bolts
- 4-inch inside diameter fits around most tractor frame rails and implement bars
- 5-1/2-inch length gives you plenty of thread engagement for thick mounting plates
- Agricultural-grade steel construction built to handle farm equipment stress
- Square shape prevents rotation when tightening – no need for backup wrenches
Built for Real Farm Work
This U-bolt is sized perfectly for mounting accessories on most utility and row-crop tractors. Whether you’re securing a tool box to your three-point arms, mounting a spray tank bracket, or building custom implements in your shop, the 4-inch opening clamps around standard frame rails and square tubing used in agricultural equipment.
Made to Last
Farm equipment takes a beating, and your mounting hardware needs to keep up. This square U-bolt is built from agricultural-grade steel that resists the constant vibration, weather exposure, and stress that comes with field work. The square design distributes load better than round bolts and won’t work loose under heavy use.
Good to Know
The square shape is your friend here – it grips the mounting surface and prevents the bolt from spinning when you’re tightening the nuts. Always use grade 5 or better nuts and washers with this bolt for maximum holding power. If you’re mounting through painted surfaces, consider using lock washers to prevent loosening from expansion and contraction.
