Zinc Yellow Hex Bolt 3/8" x 3-1/2" UNC for Farm Equipment Assembly SKU: QT3289

When standard hardware store bolts fail under farm equipment stress, you need a fastener built for agricultural conditions. This 3/8" x 3-1/2" UNC hex bolt handles the everyday mounting and assembly jobs that keep your equipment running—from securing implement brackets to assembling custom fabrication projects.

Why This Bolt Works Better

• Zinc and yellow plating provides superior corrosion resistance against fertilizers, moisture, and chemicals
• 3-1/2" length perfect for bolting through thick steel plates or sandwiching multiple components
• UNC thread pitch ensures compatibility with standard farm equipment hardware
• Agricultural-grade steel construction withstands vibration and weather cycles

This length and diameter combination works well for mounting implements to three-point hitches, securing loader brackets, and general equipment assembly where you need to span thicker materials.
