These screws have the smallest head and are the easiest to insert. They are the best in the world for attaching stair parts. This patented system gives you a squeak free, extremely strong and remarkably easy fastener. These are a must for attaching stair treads and risers to the undercarriage of your home. These screws are also strong enough for attaching handrails to newel posts, rosettes, fittings and many other applications. These require almost zero force once the screw is started because of the “W” cut and the drilling point. Choose 6 or more per tread. Pre-drilling is only necessary in prefinished product or exotic species treads.
