Abstract
A bolt guard assembly utilizes a central sleeve and first and second end caps to separate a metal fastening nut and bolt from a pair of wood products that have been treated with a preservative. The bolt guard assembly is formed of a plastic material and prevents the metal fastener from coming into contact with the treated wood products. The central sleeve is sized to telescopingly cooperate with barrel ends of the two end caps. Each of these end caps is structured having a fastener head or nut receiving pocket which receives the head or nut of the fastener and isolates them from the wood. Fastener life is greatly increased through use of the bolt guard assembly.
