Product Overview:

When you are fastening outdoor work, you want hardware that feels plain solid in your hand. This carriage bolt gives you that. The 3/8 inch by 3 inch size, Grade 2 steel, and hot dipped galvanized finish make it a practical pick for decks, docks, and other weather hit projects.

• Round head: The smooth head sits neatly once installed, so the finished work looks tidy and easy on the eye.
• Coarse thread: It bites into treated lumber with a sure grip, giving you a firmer hold and less wobble.
