Hillman 3/8-in x 2-in Galvanized Coarse Thread Exterior Carriage Bolt (10-Count)

Carriage bolts are designed to fasten a wooden face to either a wood or metal frame. Its smooth, rounded head is designed to eliminate the need for a washer and provide a semi-flush finish to applications. The square underside of the head is self-locking to eliminate spinning and the need for a driving tool. The galvanized finish provides optimal rust prevention but can be chalky in appearance. These bolts measure 3/8-in wide and 2-in long. They feature 16 screw threads per inch. Matching galvanized hex nuts are included in the package.
