Ring shank nails optimize holding power in wood floors. As the nail is driven, the wood tightens and grips the barbed rings. This promises a firm hold in any wood substrate. Our ring shank nails also have countersunk heads. A coutnersunk head lets the nails "sink" to create a flus substrate. Ring shank nails are used in tack strip, underlayment installations, and reinforcing existing subfloors made of plywood or other wood products. At Traxx, ring shank nails are zinc plated to prevent any corrosion from water based patch or adhesive.
