Description
When you’re putting together heavy equipment that needs to stay together no matter what, you don’t mess around with hardware store bolts. This 3/4-inch Grade 8 hex bolt is built for the kind of stress and punishment that farm equipment dishes out—from loader brackets that lift tons to implement frames that get bounced through rocky fields.
What You’re Getting
- Grade 8 strength rating—about 50% stronger than Grade 5 bolts for maximum holding power
- Zinc coating protects against rust and corrosion in wet field conditions
- Standard UNC coarse threads for reliable engagement in agricultural applications
- 5-1/2 inch length handles thick assemblies and multiple pieces perfectly
- 3/4-inch diameter provides serious clamping force for heavy-duty connections
Built for Real Farm Work
This bolt size is what you’ll find holding together the serious stuff on your farm—three-point hitch assemblies, loader arms, cultivator gangs, and structural connections on combines and other heavy equipment. The 3/4-inch diameter gives you the strength to handle high-stress applications where smaller bolts just won’t cut it.
Made to Last
Grade 8 bolts are the top shelf when it comes to strength—they’re heat-treated to handle extreme loads without stretching or failing. The zinc plating keeps corrosion at bay even when you’re working in muddy conditions or dealing with fertilizer and chemical exposure that would eat up uncoated bolts.
Good to Know
You’ll need a 1-1/8 inch wrench or socket for installation. The 5-1/2 inch length is perfect for through-bolting thick steel plates or when you need to sandwich multiple brackets together with washers and nuts. Always torque to spec for Grade 8 hardware—these bolts can handle serious tightening.
