A screw includes two types of threads which the first threads located close to the point of the shank and the second threads extend from the head of the screw, the two threads spiral in opposite direction. Said first threads have the outside diameter larger than the outside diameter of the...
Similar to a machine screw except the lower part of the shaft is designed to cut threads as the screw is driven into an untapped hole. The advantage of this screw type over a self-tapping screw is that, if the screw is reinstalled, new threads are not cut as the screw is driven. Set...
