Sirius Plastic Nut Cover Cap Black

The Sirius Plastic Nut Cover Cap Black in M16 is built for use with larger M16 metric nuts, making it well suited to heavy-duty construction, structural steelwork, and industrial fabrication projects. Supplied in a pack of 50, it provides a practical quantity for professional use. The M16 size covers one of the more substantial nut sizes in common use, and these caps offer a clean snap-fit finish that conceals the exposed fixing while guarding against moisture, dirt, and surface corrosion. The black colour blends discreetly with most materials and finishes. Features and Ben
