Description

You’re tightening down brackets, fixing deck attachments, or replacing worn bolts on your equipment—and you need hardware that’ll stay put when things get bumpy. This 5/16-inch Grade 5 hex bolt gives you the strength and reliability to handle whatever your farm throws at it, from planter repairs to loader mount fixes.

What You’re Getting

Grade 5 strength rating—tougher than standard hardware store bolts and perfect for agricultural applications
Zinc-plated finish that resists rust and corrosion, even in wet or dusty conditions
UNC thread pitch for standard compatibility with nuts and threaded holes
2-1/2 inch length handles most common mounting and repair situations

Built for Real Farm Work

This size bolt is a workhorse for medium-duty applications across all kinds of farm equipment. You’ll find it holding down PTO shields, securing hydraulic line brackets, mounting implement accessories, and fixing deck hardware on everything from compact tractors to mid-size utility machines. It’s the right size for jobs where a 1/4-inch bolt isn’t quite enough but a 3/8-inch is overkill.

Made to Last

Grade 5 bolts are heat-treated for higher tensile strength than Grade 2 hardware, so they won’t stretch or snap under load. The zinc coating adds a layer of protection against the moisture and chemicals that farm equipment deals with every day, keeping threads clean and making future removal easier.

Good to Know

Always use a Grade 5 or better nut with this bolt to get the full strength rating. If you’re replacing an original bolt, this is likely the same grade that came from the factory. Keep a few extras in your toolbox—you’ll be surprised how often this size comes in handy for quick repairs.
