Description

When you’re building or repairing farm equipment, you need hardware that won’t let you down in the middle of harvest. This Grade 5 carriage bolt gives you the strength and corrosion resistance to handle whatever your operation throws at it. The smooth rounded head and square shoulder design keeps things secure without snagging on anything, while the zinc coating protects against rust season after season.

What You’re Getting

Grade 5 strength that’s 25% stronger than hardware store bolts but costs less than Grade 8
Zinc plating stands up to moisture and road salt so it won’t rust out in a year or two
Square shoulder under the head prevents spinning when you tighten the nut
UNC thread pitch works with standard nuts and washers you’ve got on hand
3-inch length handles thick materials or when you need to sandwich multiple pieces together

Built for Real Farm Work

This size bolt is perfect for medium-duty connections on tractors, implements, and shop-built equipment. You’ll find 1/2-inch carriage bolts holding together everything from cultivator frames to three-point hitch attachments and custom brackets. The smooth head design makes them especially handy where you don’t want bolt heads catching on moving parts or clothing.

Made to Last

These bolts are built to handle the vibration, weather, and hard use that comes with farm life. The Grade 5 steel gives you the strength you need without breaking the budget, while the zinc coating helps them stand up to the elements so you’re not replacing rusty hardware every few seasons.

Good to Know

Always use a flat washer under the nut to distribute the load properly and prevent the wood or metal from crushing. If you’re replacing rusted bolts, clean out the hole and threads first. A little anti-seize compound on the threads makes future removal much easier, especially if the connection might see moisture or road salt.
