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
Exterior duplex coating is 20x more corrosion-resistant than zinc and 2x more corrosion-resistant than galvanized
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
Limited Lifetime Warranty against rust and corrosion

What Customers Are Saying

Customers overwhelmingly praise these carriage bolts for exceptional durability and reliability in outdoor construction. The epoxy coating and black finish consistently prevent rust even after prolonged exposure and heavy use, making them ideal for decks, swing sets, and cabin builds. Reviewers confirm perfect sizing and thread quality for joining 4x4 posts and 2x8 lumber, with smooth assembly and secure holding. The solid black construction receives frequent approval for both strength and professional appearance. A few mention price concerns, but performance satisfaction remains nearly universal.
