Description

When you’re putting a plow back together or replacing worn moldboard bolts, you need fasteners that won’t let you down halfway through the season. This Grade 8 plow bolt is built for the punishment that comes with turning dirt, rocks, and whatever else is hiding in your fields. The countersunk head sits flush so it won’t catch on debris or wear out your moldboards prematurely.

What You’re Getting

Grade 8 steel construction that’s tougher than standard hardware store bolts—won’t snap under heavy loads
Countersunk head design sits flush to prevent snagging and reduces wear on your plow parts
1/2-13 thread pitch gives you strong holding power in standard agricultural applications
4-inch length handles most moldboard and share mounting situations without needing washers or spacers
Zinc finish resists rust and corrosion even in wet field conditions

Built for Real Farm Work

This is the classic Number 3 plow bolt that’s been holding moldboards and shares to plowframes for decades. Whether you’re running an old 3-bottom or maintaining a big field cultivator, this bolt size shows up everywhere in tillage equipment. It’s what most manufacturers spec for attaching moldboards, shares, and other working parts that take a beating.

Made to Last

Grade 8 bolts are about 25% stronger than Grade 5 and way tougher than anything you’ll find at the local hardware store. When you hit a rock or root, this bolt flexes instead of snapping, keeping you in the field instead of headed to town for parts. The zinc coating holds up to mud, moisture, and fertilizer without rusting away.

Good to Know

The countersunk head means you’ll need a socket or box-end wrench instead of an open-end to tighten it properly. A little anti-seize on the threads makes removal easier when it’s time to flip or replace your moldboards. Keep a few extras in the toolbox—there’s nothing worse than breaking a bolt in the field and having to limp home with a dragging plow.
