The Hex Washer Head Self Drilling Screw is a type of screw that features a hexagonal head with an integrated washer, designed for self-drilling without the need for pre-drilled holes. The head typically includes a built-in washer that helps distribute pressure and improve the contact area, ensuring a firm hold and enhanced sealing. The tip of the screw is designed like a drill bit, allowing it to create its own hole as it is driven into materials.
Hex Washer Head Self Drilling Screws are commonly used across various industries, particularly where there is a need to fasten materials such as metal, wood, or composite materials without pre-drilling. Common applications include:
The internal performance of Hex Washer Head Self Drilling Screws is characterized by their drilling capacity, fastening strength, and corrosion resistance.
