Description
When you’re working on equipment that takes a beating—whether it’s a loader bracket that’s constantly under stress or an implement frame that sees thousands of acres—you need fasteners that won’t let you down. This Grade 8 hex bolt gives you the strength and reliability to handle those tough connections where a standard bolt just isn’t enough.
What You’re Getting
- Grade 8 steel construction delivers maximum tensile strength for the most demanding applications
- Zinc plating protects against rust and corrosion in harsh farm environments
- UNC thread pitch provides secure, reliable threading that won’t strip under torque
- 7/16-inch diameter with 1-1/2 inch length handles medium-duty through-bolt applications
Built for Real Farm Work
This bolt size is perfect for securing implement attachments, mounting hydraulic cylinders, and connecting structural components on tractors and equipment. You’ll find this size holding together everything from cultivator frames to three-point hitch components where you need serious holding power but don’t have room for larger fasteners.
Made to Last
Grade 8 steel means this bolt can handle nearly twice the stress of a Grade 5 bolt and way more than any hardware store fastener. The zinc coating helps it stand up to moisture, fertilizers, and road chemicals that would eat through unprotected steel in no time.
Good to Know
Use a 5/8-inch socket or wrench for installation, and don’t forget to pair it with a Grade 8 nut for maximum strength. If you’re replacing rusted bolts, clean the threads first and consider using anti-seize compound to make future maintenance easier. These bolts are overkill for light-duty work, but when failure isn’t an option, they’re worth every penny.
