【High-Strength Carbon Steel Construction】These double-ended nails are made from one-piece molded carbon steel, designed for strength and resistance to oxidation, corrosion, and rust to support extended use. 【Tool-Included for Easy Installation】The set includes a specialized insertion sleeve. To install, place the nail base into the sleeve and drive it directly into the wall; the sharp design aims to penetrate hard surfaces like concrete for secure skirting board placement. 【Minimal-Mark & Anti-Loosening Design】Featuring high hardness and a smooth thread surface, these nails are intended to reduce visible installation marks and lower the risk of holes loosening or rusting over time. 【Flush Mount for a Clean Finish】The double-headed design allows the nail to be driven flush with the surface, promoting a discreet and clean aesthetic for baseboards and interior trim. 【Versatile for Trim and Furniture Assembly】Suitable for securing skirting boards, furniture joints, and other wooden items such as tables, chairs, stools, benches, and decorative boxes., Manufacturer: Flosfjylo
