SCREW SHANK nails are typically used in dense materials and hardwoods. The spiral thread causes them to turn into the wood when driven for holding power. Commonly used in flooring, decking, siding, and pallet applications.
RING SHANK nails are typically used in soft woods. When driven, “rings” separate the wood fibers which cause the fibers to lock back into the “rings” providing excellent holding power. Commonly used in underlayment, decking, plywood, siding, and roofing applications.
