Description
When you’re working on tractors and implements, you need fasteners you can count on. This Grade 5 hex bolt gives you the strength to handle everything from mounting brackets to securing implements, while the zinc finish keeps rust at bay even when you’re dealing with morning dew and muddy conditions.
What You’re Getting
- Grade 5 strength rating handles high-stress applications without stretching or breaking
- Zinc finish protects against corrosion in wet and humid farm conditions
- UNC thread pitch works with standard nuts and threaded holes you’ll find on most equipment
- 1-1/4 inch length gives you enough thread engagement for secure connections
- 5/8 inch diameter provides solid holding power for medium-duty applications
Built for Real Farm Work
This size bolt is perfect for securing implement brackets, mounting hydraulic components, and assembling loader attachments. Common applications include securing implement frames to tractor three-point hitches, mounting heavy cultivator assemblies, connecting loader arm components, and assembling structural frameworks on combines. It’s the go-to size when you need something stronger than a 1/2 inch but don’t need the bulk of a 3/4 inch bolt.
Made to Last
Grade 5 bolts are heat-treated to handle serious loads—they’re about 50% stronger than regular Grade 2 hardware store bolts. The zinc coating isn’t just for looks either; it forms a barrier that keeps moisture and chemicals from eating away at the steel underneath, which matters when you’re working with fertilizers and field conditions.
Good to Know
You’ll need a 15/16 inch wrench or socket to tighten these properly. Don’t overtighten—snug plus about a quarter turn more is usually right for most applications. If you’re replacing rusty bolts, clean out the threads with a wire brush first so the new bolt seats properly.
