The nails are galvanized, making them rust-proof, durable, and sturdy. The nail heads are sharp, resistant to deformation, and do not easily bend during use. Pay attention to the direction of the longer end when driving the nail into the wall. Then, use a hammer to tap the nail in place, approximately one nail every half meter, depending on the length of the baseboard. After securing the nails, the baseboard can be fixed to them. These seamless threaded baseboard nails are made of metal with a smooth, evenly distributed thread surface and a length of 25.5 mm. The nails have strong grip and are not easily dislodged. The baseboard thickness should be 10 mm during installation. At the intersection of two baseboards, fix the nail as close to the intersection as possible.
