Using these Dagger - Lok wood screws is a breeze. For woodworking projects, just grab your screwdriver and start driving them in. Thanks to the Type 17 point, you don't need to pre - drill. Simply place the screw on the wood and turn. The nibs under the flat head will keep the screw from spinning and help it self - countersink. As for maintenance, keep them in a dry place to prevent rusting. If they get dirty, you can wipe them with a clean cloth. When using, make sure to match the #2 Phillips drive with the right screwdriver bit for the best results. And always check the wood you're using to ensure it's suitable for these screws, whether it's softwood or hardwood.
