About 20 of these fasteners are used to attach a 2x4 ceiling LED panel to brick using the drill bit provided. There was only one that didn't grip properly, most likely a fault in the brick, require the rest to be tightened perfectly. Worked as well or even better than Tapcon fasteners and I think the price was better. The drill bit is also well shaped and can drill many more holes, although I don't know if it will help you get through the whole bag when the zips?
