The square shoulder locks into the material as the nut is tightened.

The galvanized finish offers optimal protection against rust & corrosion.

Drill a hole in the surface material that matches the diameter of the fastener, insert the bolt, and connect the nut on the other end.

Product Description

Product Description

Carriage Bolts are designed to fasten a wooden face to either a wood or metal frame. Its flat 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.

From the Manufacturer

Carriage Bolts have a smooth, rounded head that has a small square section underneath. They are used in wood connections utilizing the square neck under the round head which will sit into the hole to prevent the head from turning. These carriage bolts come plated in zinc for moderate corrosion resistance.

Well worth it, I will buy again with my supply gets low
At about 50 cents a bolt, it's much cheaper than Lowe's at $1.13 per bolt. I make and sell picnic tables and I couldn't be happier with these. I love saving money :-)
