Screw Eyes or Lag Eye Screws serve the purpose of connecting balustrade wires to timber posts and provide support to wires used for trellis or vertical landscaping. Their design is best suited for fastening points that anchor a run of balustrading wire into a post. Once fitted, they offer a pleasing aesthetic finish. Depending on the type of timber, a shorter Lag eye screw may be preferred to ensure ample grip and avoid any possibility of torquing off a longer screw into hard timber.
