I'm planning on attached a 3/4 inch thick support piece (under table) to so= me 1 3/4 cherry. Will the standard length kreg screws be sufficient? I'd = like to skip the trip to the store. Also will be attached some 1 3/4 squar= e stretchers and again plan on using kreg screws and glue. If I use a 2" s= crew, do I need to adjust the depth of the hole? Also, I only have coarse = thread screws in the longer dimension. I know kreg recommends fine thread = for hardwood. Any big downside on coarse thread?
