Powercleats are designed for the hardwood flooring industry and are FHA and VA approved. Powercleats nails are superior-quality nails designed to ensure trouble-free nailer operation and optimum construction results. Powercleats nails are made from high-quality steel so they do not bend while being driven into hard flooring materials. They are made with a well-formed set of barbs along each nail, providing the ultimate holding power. The design aids in driving them into hard flooring materials, which helps to eliminate split tongues in floorboards.For use on 3/8", 1/2", 5/8", & Some 3/4" Exotic Tongue & Groove Flooring. Our new patented "HD HEAD" design allows the cleat to seat deeper and more flush for greater holding power and helps prevent dimpling.
