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 zinc plating is rust resistant and provides a beautiful, consistent finish; but, may not work for all exterior projects.

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.

Ryan
5.0 out of 5 stars Awesome!
Reviewed in the United States on June 23, 2018
Verified Purchase
These are just the same as what you find in your local hardware store or possibly better. They are 3/8“ with #16 coarse thread. Shiny silver finish. Threads are all clean and easy to start. I use these to attach the legs to cornhole boards with wing nuts on the ends. 3.5" is the perfect length to go through two 2x4's. Would buy again.
