The Nylon Plug Sleeve is stronger than ordinary-grade plastic expansion plugs, and these high-quality wall plugs are intended for use with all screw fixings in masonry and concrete. The high-impact load and knock-in protection avoid installation deformation. The drill hole is winged to avoid spinning. M-teeth, in conjunction with side links and a screw guide, guarantee that the whole plug face is pressed against the hole walls, resulting in improved grip in soft materials. When the expansion occurs, the offset block profile helps the plug to cling firmly against the edges of the hole. The broad neck is not susceptible to expansion pressure, which protects the surface of tiles and plaster.
