This product is a special plastic connecting fastener for WPC decking, a core supporting accessory for economical WPC paving, designed specifically for fast and lightweight installation of floors. Made of high-strength engineering plastic through one-piece injection molding, the structure is precisely adapted to the tongue-and-groove slots of WPC decking. It realizes stable splicing between floors through snap-on/lock-on connection, no additional drilling is required during installation, and it can be directly embedded into the floor splicing position to complete fixation. The product has good corrosion resistance and adaptability, which can effectively ensure the flatness of floor paving,  and at the same time avoid scratches caused by direct contact between metal and the floor, balancing practicality and cost performance.
