Description

When you’re working on implements or making repairs in the shop, you need bolts that won’t let you down when the going gets tough. This Grade 8 hex bolt delivers the kind of strength that handles heavy loads, vibration, and the punishment that comes with real farm work. At 5/8 inch diameter and 3-1/2 inches long, it’s sized right for securing heavy components that need to stay put.

What You’re Getting

• Grade 8 steel construction – nearly twice as strong as standard Grade 5 bolts
• Zinc plating protects against rust and corrosion in outdoor conditions
• UNC thread pitch gives you solid holding power and easy installation
• 3-1/2 inch length handles thick mounting plates and structural connections
• Precision hex head works with standard sockets and wrenches

Built for Real Farm Work

This bolt size is perfect for heavy-duty connections on cultivators, disc harrows, plows, and other tillage equipment. Common applications include securing implement frames to tractor three-point hitches, mounting heavy cultivator assemblies, connecting loader arm components, and assembling structural frameworks on various agricultural equipment. Whether you’re bolting on new shanks, mounting brackets, or assembling shop-built implements, this bolt handles the job.

Made to Last

This specialized fastener is essential for heavy-duty agricultural and construction equipment where structural integrity is paramount. The Grade 8 rating means it’s heat-treated to handle extreme stress without stretching or breaking. The zinc plating system provides superior corrosion resistance compared to standard zinc plating, extending service life in agricultural environments where exposure to fertilizers, moisture, and chemicals is common.

Good to Know

Grade 8 bolts require a bit more torque than Grade 5, so check your specifications if you’re doing critical assemblies. The zinc finish means it’ll thread easily and won’t seize up like bare steel. Keep a few extras on hand – you’ll appreciate having the right bolt when you need it most.
