The patented Outdoor Accents® hex head washer and structural wood screw combination provides the decorative appearance of a bolted connection. Its design provides an easier and significantly faster installation time compared to through-bolting. The hex head washer is code listed (IAPMO UES ER-192) and is designed to be used exclusively with the Outdoor Accents® structural wood screw to fasten Outdoor Accents® connectors, including post-bases, T and L-straps, angles, gable plates and heavy joist hangers.
