Description
Whether you’re patching up a cultivator or building custom brackets in the shop, having the right bolt on hand can save you a trip to town when you’re in the middle of a project. This 7/16-inch x 2.5-inch UNF bolt with zinc and yellow coating is the kind of versatile fastener that belongs on every farm workbench.
What You’re Getting
- Fine UNF threads that hold tighter than standard coarse threads—perfect for precision connections
- Zinc and yellow coating that resists rust and corrosion better than plain steel bolts
- 2.5-inch length gives you good thread engagement without excess bolt sticking out
- 7/16-inch diameter offers solid strength for medium-duty farm applications
Built for Real Farm Work
This general-purpose bolt works across all kinds of agricultural equipment and shop projects. You’ll find yourself reaching for this size when you’re working on cultivator points, bracket assemblies, or any job where you need a strong connection that won’t vibrate loose. The fine thread pitch means more threads per inch, which translates to better holding power in critical applications.
Made to Last
The zinc plating with yellow chromate finish isn’t just for looks—it’s your protection against moisture, fertilizer spray, and the general abuse that farm hardware takes. This coating helps the bolt threads stay smooth and prevents that annoying seizing that happens with cheap hardware store bolts after a season in the field.
Good to Know
UNF threads require a matching fine-thread nut, so double-check what you’re replacing before ordering. The fine threads cut cleaner and hold better than coarse threads, but they’re a bit more delicate during installation. A drop of oil on the threads makes assembly easier and helps prevent cross-threading, especially in cold weather.
