Built for Real Farm Work
This bolt size hits the sweet spot for medium-duty connections on tractors and implements. You’ll find 5/16-inch bolts holding together cultivator components, securing brackets and shields, and fastening various accessories to your equipment. The 3-inch length gives you plenty of working room when you need to bolt through thicker steel or sandwich washers and spacers.
Made to Last
The zinc and yellow coating isn’t just for looks—it’s your protection against the moisture, mud, and chemicals that farm equipment faces every day. This coating system helps the threads stay clean and the bolt heads resist corrosion so they’ll still look good and work properly seasons down the road.
Good to Know
Always use a flat washer under both the head and nut to spread the load and prevent the bolt from pulling through thinner materials. Keep a few extra bolts in your toolbox since 5/16-inch is a common size that seems to walk away during field repairs. A drop of thread locker on critical connections helps prevent loosening from vibration.
