    Description

    When you're building or repairing equipment, you need fasteners that won't let you down. This 5/8 inch x 3 inch carriage bolt is built tough with Grade 5 strength and a zinc coating that fights off rust and corrosion. The square neck design keeps the bolt from spinning when you're tightening the nut—a real time-saver when you're working alone.

    What You're Getting

    • Grade 5 steel construction provides reliable strength for medium to heavy-duty applications
    • Zinc plating resists corrosion and gives you longer service life outdoors
    • Square neck under the round head prevents the bolt from spinning during assembly
    • 3-inch length handles thick materials and gives plenty of thread engagement
    • UNC thread pitch works with standard nuts and washers you already have

    Built for Real Farm Work

    This carriage bolt is perfect for securing guards, mounting brackets, and assembling framework on all kinds of farm equipment. The 5/8 inch diameter and Grade 5 strength make it ideal for implements, loader attachments, and structural connections that see regular use but don't need the expense of Grade 8 hardware.

    Made to Last

    The zinc coating isn't just for looks—it's your first line of defense against the moisture, chemicals, and weather that farm equipment faces every day. Grade 5 steel gives you the strength you need without breaking the budget on premium fasteners where they're not required.

    Installation Notes

    The square neck fits into square holes or can be held with pliers if needed. Make sure you've got a flat washer under the nut for best results, and don't forget to check the torque specs for your application. A little anti-seize on the threads helps with future removal.
