Torx Drive CSK Head Half Thread Self Tapping Screws With Sharp Point


Product Description
When you are looking for fasteners, you are trying to evaluate the situation and pick the best way to put materials together. Fastening one or more pieces of light, medium, or heavy gage sheet metal together may require the use of adhesives, riveting, or self-tapping screws. If an application requires access or several layers, tapping screws maybe the best option.

Just like other types of fasteners, self-tapping screws are available in all shapes and sizes and are also available in numerous different head types. When choosing the right self-tapping screw for any given application, it is important to consider the length of the screw tip. In order for the screws to serve their purpose and work properly, the screw must be drilled fully into the material before threading can begin.


Self-tapping screws, mainly made of carbon steel or stainless steel, are widely used on plastics, metal and wood materials. The best part in the use of self-tapping screws is that there is no need to drill holes before they are used. The two basic types of self -tapping screws are thread-forming screws and thread-cutting screws. The thread-forming screws are commonly used for plastic, deforming the material as the screws enter. The thread-cutting screws are typically used for wood and metal, removing some of the material and creating a threaded path for the screw.
