Carriage Bolt Washers
Carriage Bolt Washers allow use of any length carriage bolt where you would otherwise use a Tufbolt. The washers raise the neck of a carriage bolt so it doesn't touch the sign face, or work surface. Made of black Nylon, these carriage bolt washers are designed to prevent the head of the bolt from being grasped and turned. The 5/16" size can also be used with a 1/4" carriage bolt.
