Shipping Details

Carriage bolts feature a smooth, dome shaped head, without an external drive for appearance, safety and security. Underneath the head is a square section that is the same diameter as the threaded portion of the bolt, allowing the bolt to be installed with just a single tool. Pre-drilled holes are required for installation.

Carriage bolts are designed to fasten a wooden face to either wood or metal
The galvanized finish provides superior weather and corrosion protection
Install by pushing the carriage bolt through a pre-drilled hole, secure placement with hex nuts and washers
Common applications include security fixings, decking, fencing, furniture, outdoor play equipment; places where the bolt must only be removable from one side
The self-locking square section on the underside of the head pulls into the wooden material as hex nuts are tightened, eliminating spinning after installation
Conforms to ASTM A153 specifications

Inaccurate Photo

This 10" bolt does not have threads that go all the way across. There is at least 3 inches of unthreaded bolt near the head. Lowes should NOT use a stock photo from the shorter ones. Very misleading.

Good solid bolts

Would Recommend

Bolts are of a quality material. Only problem was when I went to check out, Lowes only had self checkouts open and I had a lot of loose bolts, washers and nuts. Worker had to scan her card to over-ride with each and every item which took forever. If you need to purchase loose items with no scan codes go to a different hardware store.
