Using high-quality carbon steel raw materials, after quenching and hardening treatment, the hardness meets the standard; Available in coarse/fine teeth: coarse teeth are compatible with wooden keels

Conical sinking head, smoothly sinks into the gypsum board after being inserted, without scratching the gypsum paper layer. The later putty is smooth and beautiful, reducing the need for wall repair

Black phosphating surface treatment, rust and oxidation resistance, less prone to rusting in humid indoor environments, extending the service life of walls; Galvanized versions are also available

Paired with a dedicated chain strap nail gun, the plastic chain strap is orderly fixed with screws, abandoning the traditional manual screwing steps for loose screws

The screws are fixed on the plastic chain to prevent them from falling or losing during manual retrieval, which can save a lot of screw loss costs in large-scale projects;

The machine automatically controls the spacing between screws, avoiding uneven density of manual nailing. The stress on the wall is balanced in the later stage, reducing the risk of wall cracking

High strength modified plastic chain belt, good flexibility, not easy to break when bent, screws do not fall off during transportation, suitable for high-speed operation of continuous firing guns

Integrated processing of chain belt forming and screw assembly, with a tight fit between the chain belt and screws, high pass rate on the machine, and minimal occurrence of gun jamming problems

The factory price is affordable, and the advantage of bulk procurement is obvious. The comprehensive cost of long-term engineering procurement is lower than that of bulk drywall nails.
