Description
When you’re out in the field and need a sturdy bolt that won’t let you down, this 9/16″ x 3″ UNF zinc-plated bolt is what you reach for. Whether you’re mounting implements, securing guards, or handling repairs on the go, this heavy-duty fastener gives you the reliable connection you need to keep working without worrying about comebacks.
What You’re Getting
- 9/16″ diameter with UNF (fine) threads for stronger hold and better vibration resistance than coarse threads
- 3-inch length provides plenty of thread engagement for solid, secure connections
- Zinc and yellow plating protects against rust and corrosion in wet field conditions
- Heavy-duty construction handles the loads and stress that farm equipment dishes out
Built for Real Farm Work
This is your go-to bolt for general purpose applications across all kinds of tractors and equipment. UNF fine threads are especially useful when you need that extra holding power and resistance to loosening from vibration—perfect for implement attachments, bracket mounting, and structural connections that take a beating during field work.
Made to Last
The zinc and yellow plating isn’t just for looks—it’s a proven corrosion protection system that stands up to moisture, fertilizers, and the harsh conditions your equipment faces every day. The fine thread pitch gives you more thread contact area, which means better clamping force and less chance of loosening up over time.
Good to Know
UNF threads are finer than standard UNC threads, so they thread in slower but hold tighter—worth the extra few turns when you need a connection that stays put. Keep a few of these on hand in your toolbox since they’re handy for all sorts of repairs and modifications around the farm.
