Carriage bolt construction is standard on many wood chairs and bar stools and is available as an option on most other items. Standard lag bolts are removed and a carriage bolt is installed from the outside of the back leg, through the seat rim. This method of construction adds strength and longevity to the product. Carriage bolts are available in brass, chrome, black and statuary bronze finishes. Brass plated bolts are standard, but M. Deitz and Sons, Inc. will use at its discretion the bolt color that we feel will be appropriate unless a specific color of bolt is requested on the purchase order.
