Hex Bolt 3/8 x 4-1/2 UNF Thread with Zinc Yellow Plating SKU: QT2876

When critical agricultural connections start to fail, it's often because standard hardware store bolts can't handle the constant vibration and harsh conditions. This zinc and yellow plated hex bolt gives you the precise 3/8 UNF threading and corrosion resistance your farm equipment demands for reliable, long-lasting connections.

Why This Fastener Works

• UNF fine thread provides stronger holding power than coarse threads in critical applications
• Zinc yellow plating delivers superior corrosion resistance against fertilizers, moisture, and farm chemicals
• 4-1/2 inch length handles thick brackets and multiple component assemblies
• Hex head design allows proper torque application with standard tools

This agricultural-grade fastener handles the demanding environment your equipment faces every day. When you need a bolt that won't loosen, corrode, or fail when it matters most, this is the reliable choice backed by S&H Parts' 55 years of farm equipment expertise.
