    Thumb Screws, like Wing Nuts, are made to be tightened and loosened with finger pressure and are typically used where frequent adjustment or disassembly is required. They are fully threaded. Length of Spade Head (Type P) screws is measured from under the head to the tip. Spade Head with Shoulder (Type S) screws are measured from under the shoulder to the tip. The shoulder adds a bearing surface.
