TIMco In-Dex Timber screws are designed for decking, stairs, fencing, roofing and landscaping. Plated in olive green to withstand up to 1,000 hours (min) salt spray resistance. They have a 50-degree deep single thread to provide secure fixing with a high pull-out resistance and a type 17 slash to reduce torque and the likelihood of the timber splitting when the screw is inserted close to the edge. They also have a 25-degree sharp point for easier penetration into all wood types. The washer head provides extra pull down power compared to the standard hexagon head In-Dex screws, which makes these screws particularly effective for screwing warped timbers together, or fixing timber sleepers together.
