5/16-18 x 6 Carriage Bolts

These 5/16-18 x 6 Carriage Bolts from Midwest are crafted from low-carbon steel, ensuring durability and strength for a wide range of fastening needs. Featuring a large, domed head, they provide a clean finished appearance and maximum holding power, especially in wood applications. The head stamping allows for easy class and grade identification even after installation, while the precise threading ensures smooth engagement and secure connections that hold up under stress.

Finished with a zinc coating, these bolts offer moderate corrosion resistance, making them suitable for many indoor and outdoor projects. However, they are not recommended for use with chemically treated wood—hot-dipped galvanized fasteners should be used in those cases. Ideal for construction, woodworking, and general repair tasks, these carriage bolts combine reliable performance with a professional look, making them a dependable choice for both contractors and DIY enthusiasts.
