The Outdoor Accents hex-head washer provides the decorative appearance of a bolted connection. Its patent-pending design provides an easier and significantly faster installation time compared to through-bolting. The patent-pending hex-head washer is code listed (IAPMO-UES ER-192) and is designed exclusively to help fasten Outdoor Accents post bases, T and L straps, angles, gable plates and heavy joist hangers.
