A tapping point, however, is designed for blind holes, where the screw does not need to pass entirely through the material. In contrast, thread cutting screws have a sharp, flute-ground cutting edge that removes a precise chip of material, allowing them to create a thread in harder materials such as steel or pre-drilled plastics.
Understanding the Tapping Screw Material Displacement Process
As torque is applied, the thread form pushes against the drilled hole’s wall, displacing the material to form a tight, interlocking fit. This process is distinct from drilling, as it relies on plastic deformation rather than simple material removal.
The point of the screw is engineered for specific functions. Lubrication is often recommended, particularly for harder materials, to reduce friction and heat buildup, which can compromise the screw’s mechanical properties.
Understanding the Material Displacement Process of Tapping Screws
This self-generating action is achieved through a precisely engineered geometry on the screw’s flank, which removes material and compresses it to form the ridge of the thread. The primary advantage lies in the speed of assembly; they eliminate the need for drilling, tapping, and threading operations, streamlining production lines and reducing labor costs significantly.
