Description
When you need a clean, finished look on equipment panels, guards, and brackets, carriage bolts are the way to go. That smooth, rounded head sits flush against surfaces and won’t snag on clothing or catch debris like hex bolts do. This 3/8-inch by 2-inch size handles most light to medium-duty connections around the farm, from mounting implement shields to assembling shop-built equipment.
What You’re Getting
- Grade 5 strength that’s 25% stronger than hardware store bolts but costs less than Grade 8
- Zinc plating resists rust and corrosion from moisture, road salt, and farm chemicals
- Square shoulder under the head prevents spinning when you tighten the nut
- Standard UNC thread pitch works with common nuts and threaded rod
- 2-inch length works great for bolting through standard steel plate and brackets
Built for Real Farm Work
This bolt size fits perfectly for mounting equipment guards, assembling three-point hitch accessories, securing toolbox brackets, and general shop fabrication work. You’ll find these bolts holding together everything from cultivator shields to loader attachments where you want that clean, professional appearance without sharp edges or protruding bolt heads.
Made to Last
The zinc coating helps these bolts stand up to the weather and won’t rust out in a season or two like uncoated hardware. Grade 5 steel gives you the strength you need without paying premium prices, making them perfect for most farm applications that don’t require extreme loads.
Good to Know
Always use a flat washer under the nut to distribute the load and prevent pull-through on thin materials. The square shoulder needs to seat properly in the hole to prevent spinning, so drill clean holes that match the bolt diameter. A little anti-seize compound on the threads makes future removal much easier, especially if the connection might see moisture or road salt.
