Raptor Nails And Staples

The following lists the density of some woods. Drivability of RAPTOR^® fasteners depends on the density and hardness of the substrate and the shape of the fastener (length/diameter). Shorter thicker nails will drive into harder substrates easier than long, thin nails. RAPTOR staples will drive into harder substrates if pneumatic tools are used rather than manual tools. While some customers are using shorter staples and brads in oak and maple (Group l), longer nails are limited to soft wood applications (Group lll & lV). Woods with very dense latewood growth rings do not give good performance with RAPTOR products.
