Description
Engineered for outdoor strength and long-lasting performance, these A307 Grade A steel carriage bolts feature a hot-dipped galvanized finish for superior corrosion resistance in damp or exposed environments. The 1/4-20 coarse thread and 1-inch length make them ideal for timber-to-timber assemblies.
Designed with a domed carriage bolt head and a square under the head, these fasteners resist turning when tightened into pre-drilled holes in wood. The hot-dip galvanizing provides a durable zinc coating that helps protect against rust and corrosion in outdoor projects such as decking, fencing, and rough-cut timber connections.
