Csk head self-drilling screws from LITUO Fasteners are highly durable and corrosion-resistant, which allows it to be used in extreme temperatures and undersea applications as well. Since these screws are self-drilling, they can be used without drilling the pilot hole. Depending on the size, the applications of the CSK self-drilling screws can vary – the smaller screws are used in applications like fixing thin gauge metals and fixing metal to wood. The larger screws are used in roofing and other industries which require self-drilling through tough metals. Our screws come in stainless steel, alloy steel, carbon steel, and other materials that prevent corrosion.
If the CSK head self-drilling screws are used in extremely hard materials, it is advised to use it after a pilot hole has been drilled. Our screws are case hardened and heat-treated for applications requiring fastening of soft materials on hard ones. With a lower installation torque, the threads on these screws allow for a quick transition from drilling to tapping. For effective penetration, make sure that at least three threads of the fastener are inside the material.
It can also be used for lighter applications like securing wood to metal. Since they are slotted, they can be removed using a screwdriver. Due to the excellent proportions with which these screws have been engineered, they often give an aesthetically pleasing look to the finished product or component.
Application: Self-drilling screws have hardened drill points that will drill and thread in structural steel, mild steel, aluminum, and wood.
