300mm Hex Head Timber Screws

300mm Hex Head Timber Screws for oversized timber beams and heavy landscaping structures. Each screw is made from heat-treated carbon steel for maximum torsional strength and long-term performance. A Ruspert-coated surface provides advanced corrosion resistance through a three-layer metallic system comprising a zinc base coat, chemical conversion film, and ceramic top layer. The hexagonal drive head with integral washer face ensures high clamping pressure, preventing timber movement and pull-through under load. The coarse thread delivers fast cutting and high pull-out resistance in softwood, treated wood, and heavy sections. A gimlet point - a self-tapping, tapered tip - allows for fast starting and penetration without the need for full pre-drilling, saving installation time while reducing timber splitting.
