Grade 5 Zinc Carriage Bolt for Heavy-Duty Farm Equipment and Tractor Applications

Description

When you’re fixing brackets, mounting implements, or rebuilding equipment, you need hardware that won’t let you down in the middle of harvest. This 1/2-inch carriage bolt with its 3-1/2 inch length gives you the strength and reach for those heavier mounting jobs around the farm. The square shoulder locks into place so things stay put even when the ground gets rough.

What You’re Getting

• Grade 5 strength rating handles the stress and vibration that comes with farm work
• Zinc coating fights off rust and corrosion from weather and chemicals
• Square shoulder design prevents spinning when you’re tightening things down
• UNC thread pitch works with standard nuts and fits most equipment
• 3-1/2 inch length gives you plenty of thread engagement for thick brackets and spacers

Built for Real Farm Work

This bolt is right at home mounting loader brackets, securing implement frames, or fixing deck hangers on mowers. The 1/2-inch size is commonly used for parallel arm assemblies and other heavy-duty mounting points where you need serious holding power. Whether you’re working on tractors, combines, or tillage equipment, this is the kind of hardware that keeps things together season after season.

Made to Last

Farm bolts take a beating from mud, moisture, salt, and constant vibration. The Grade 5 steel gives you the tensile strength to handle loads without snapping, while the zinc coating adds a protective barrier that keeps corrosion at bay. This isn’t hardware store quality—it’s built for the demands of agricultural equipment.

Good to Know

The square shoulder underneath the head is what makes carriage bolts special—it bites into the material and prevents the bolt from spinning when you’re tightening the nut. Make sure your mounting hole is the right size so the shoulder seats properly. A little anti-seize on the threads makes future removal easier if you’re working in areas that see a lot of moisture.
