Description
When you’re knee-deep in a repair and need a reliable nut that won’t strip or fail when you need it most, this 5/16-inch hex nut delivers the dependability you’re looking for. Grade 2 steel gives you plenty of strength for most farm applications without the premium price, and the zinc plating helps it stand up to moisture and road salt so it won’t rust out on you.
What You’re Getting
- Grade 2 steel construction that’s stronger than standard hardware store nuts
- UNF (fine) thread pitch for tighter engagement and better holding power
- Zinc plating protects against corrosion and extends service life
- Standard hex design works with any 5/16-inch wrench or socket
Built for Real Farm Work
This size nut is perfect for lighter to medium-duty connections on tractors, implements, and shop-built equipment. You’ll find 5/16-inch fasteners holding together everything from sheet metal panels to brackets and smaller structural components. The fine thread pitch gives you more threads per inch, which means better clamping force and less chance of backing off under vibration.
Made to Last
Grade 2 nuts offer good strength for most agricultural applications while keeping costs reasonable. The zinc coating helps them resist the moisture, fertilizer, and road salt that can eat up unprotected steel fasteners in just a season or two.
Good to Know
Fine thread nuts require matching fine thread bolts—they won’t work with coarse thread hardware. If you’re replacing a stripped nut, double-check that the bolt threads are in good shape too. A drop of medium-strength thread locker can help prevent loosening in high-vibration applications.
