OZCO Ornamental Wood Ties (OWT) Timber Bolts are an innovation in structural design. OWT Timber Bolts replace standard thread-all, carriage, or similar through-bolt fasteners while helping you finish projects faster with a more professional finish. OWT Timber Bolts are perfect for any wood-to-wood projects and are designed to eliminate trimming of unsightly and potentially dangerous bolt ends. The hex cap nut design prevents the outside coating from being marred or damaged. While all of our OWT Building Products are designed for exterior projects, they are also outstanding for interior design projects, from architecture to furnishings.
