- Self Drilling Screw With Washer
Self Drilling Screw With Washer is a self-tapping screw with a washer design, typically made of metal or plastic. This type of screw can be directly drilled into materials without the need for pre-drilling. The washer design provides additional waterproofing and sealing functionality, as well as increased stability and holding power for the screw.
The design of this screw greatly simplifies the installation process as users do not need to pre-drill. They are commonly used for connecting thinner metal sheets, such as roofs and walls. The washer also provides additional protection to prevent water and other substances from seeping into the screw hole, which could reduce the strength and reliability of the screw.
The size and shape of this screw can be adjusted according to specific needs. They are typically made of stainless steel or carbon steel and can be surface-treated to improve durability and corrosion resistance.
