Pre-assembled grey nylon plugs with zinc yellow passivated screw nails are designed for quick, easy, and repetitive installation. They can be installed using a hammer for the final fix. The Pozidrive compatible screw head allows for easy release if needed. With a strong grip in solid substrates, these fixings are ideal for through fixing, which eliminates the need for marking and repositioning. Commonly used for batten, window, and door frame fixing, they are suitable for most masonry substrates, including concrete and brickwork.
