Description

When you’re fixing equipment or building something that needs to stay put, you need a bolt you can trust. This 3/8 inch Grade 5 hex bolt gives you the strength and reliability that farm work demands, whether you’re mounting brackets, securing guards, or putting together implement parts that take a beating.

What You’re Getting

Grade 5 strength rating handles medium to heavy-duty applications without breaking or stretching
Zinc plating fights off rust and corrosion so your connections stay solid season after season
Standard UNC thread pitch works with most nuts and threaded holes you’ll find on farm equipment
2-1/2 inch length gives you plenty of thread engagement for secure fastening through multiple layers
Six-sided hex head lets you get a good grip with standard wrenches and sockets

Built for Real Farm Work

This bolt size is perfect for medium-duty applications around the farm—think mounting cultivator sweeps, securing mower deck components, or assembling loader attachments. The 3/8 inch diameter handles loads that would bend smaller bolts, while the Grade 5 rating gives you more strength than standard hardware store bolts without the cost of Grade 8.

Made to Last

Grade 5 bolts offer a good balance of strength and value for most agricultural applications. The zinc coating adds a protective layer that helps prevent the bolt from rusting out, which is important when your equipment lives outside and deals with moisture, fertilizer, and everything else the farm throws at it.

Installation Notes

Always use a flat washer under the head and nut to spread the load and protect surfaces. Tighten to proper torque specs—over-tightening can actually weaken the connection. If you’re working in tight spots, the hex head gives you more wrench options than a carriage bolt would.
