Description
When you’re building that new feed bunk or repairing the bracket on your mower deck, you need hardware that won’t back out or strip when things get bumpy. This 5/16 inch carriage bolt gives you that solid, tamper-resistant connection that stays tight season after season. The square shoulder sits snug in the hole while the rounded head won’t catch on clothes or equipment like hex bolts can.
What You’re Getting
- Grade 5 strength handles the vibration and stress of farm equipment without stretching
- Zinc coating protects against rust and corrosion in wet conditions
- Smooth rounded head won’t snag on anything while the square neck prevents spinning
- Standard UNC thread pitch works with common nuts and hardware
Built for Real Farm Work
This size bolt is perfect for attaching guards and shields on tractors, securing brackets on implements, and building farm structures where you need a flush, professional look. Whether you’re mounting a PTO guard, securing loader brackets, or assembling custom equipment, the carriage bolt design keeps things looking clean while providing reliable holding power.
Made to Last
The zinc finish gives you corrosion protection that outlasts plain steel, while the Grade 5 rating means this bolt has the tensile strength to handle real loads. It’s built to the same specs as the hardware that came on your equipment from the factory, so you know it’ll do the job.
Good to Know
The square shoulder needs a square hole to work properly—round holes will let the bolt spin. If you’re drilling new holes, use a square punch or file after drilling for the best fit. The 1-inch length gives you enough thread engagement for most standard applications with a nut and washer.
