These Daggerz laminating screws are easy to use. For gypsum - to - gypsum applications, just use a compatible driver for the #2 Phillips drive. The self - centering feature will help you start the screw easily. When installing, remember that the coarse threads are designed to hold more material, so you don't have to worry about it slipping. The bugle head is made to fit flush into softer materials, so it won't stick out. For maintenance, keep them in a dry place. The phosphate finish helps with corrosion, but if they get wet, dry them quickly. Don't use these screws for applications they're not recommended for, as it may affect their performance.
