Grade 5 Hex Bolt 1/2 x 3 Inch UNC with Zinc Yellow Coating for Farm Equipment SKU: QT354655

When hardware store bolts fail on your farm equipment, you're left with costly downtime and safety concerns. This Grade 5 hex bolt delivers 25% more strength than standard Grade 2 bolts while maintaining the zinc yellow coating that resists corrosion from moisture, fertilizers, and road salt.

Why This Grade Matters

• Grade 5 construction handles the stress and vibration of agricultural equipment
• Zinc yellow plating provides superior corrosion protection over standard zinc
• UNC thread pattern ensures proper fit with existing equipment hardware
• 3-inch length accommodates thick assemblies and multiple components

Use flat washers under both head and nut to distribute load properly and prevent pull-through on thin materials. A touch of anti-seize compound makes future removal easier when connections face heat or road salt exposure.
