Built for Real Farm Work
This versatile bolt works across a wide range of agricultural equipment where you need dependable fastening. The 5/8-inch diameter and fine threads make it ideal for securing implement attachments, hydraulic components, and structural connections that see regular use and vibration.
Made to Last
The zinc and yellow coating isn’t just for looks—it’s your protection against the elements. Whether you’re dealing with morning dew, field dust, or the occasional washdown, this plating keeps corrosion at bay so your connections stay tight season after season.
Good to Know
UNF stands for Unified National Fine, which means tighter threads that grip better under stress. This makes them perfect for applications where you can’t afford to have things work loose. Always use the proper torque specs for your application, and consider pairing with a matching UNF nut for the best holding power.
