Powercleats�� nails are designed for use in Powernailer�� floor nailers and are superior quality nails. At the heart of any nailing systems is the nail. And, while many nails may look similar, there are differences in quality that can mean the difference between a successful installation or one plagued with problems. Powercleats nails are designed for use with Powernailer nailers, are superior-quality nails and are FHA and VA approved. They meet the requirements of the MFMA (Maple Flooring Manufacturers Association), NOFMA (National Oak Flooring Manufacturers Association) and NWFA (National Wood Flooring Association). Powercleats nails are made in the USA from USA produced 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. When used in conjunction with Powernail's Powernailer�� line of nailers, Powercleats�� nails ensure trouble-free operation and optimum construction results. Powercleats nails are available in all sizes to fit all flooring applications and come in conveniently sized cartons. This chart will assist you in determining the proper length of Powercleats to use for various thicknesses of flooring when the sub flooring member varies as to species and thickness. Approximate vertical penetration of the Powercleat under the hardwood floor is shown for each application. This is only a guide. Results should be tested in the field before proceeding. 16 Gauge Nails (Models 445 XL, XS, LL, LS, SL, SS)
