Product Description

Self Drilling screws are a type of screws. They are mainly used to fix color steel tiles in steel structures. They can also be used to fix thin plates in simple buildings. It cannot be used for metal-to-metal bonding. The tail of the drilling screw is in the shape of a drill tail or a pointed tail. No auxiliary processing is required. Drilling, tapping and locking can be directly performed on the installation materials and basic materials, greatly saving construction time. Compared with ordinary screws, its toughness and retention force are high, and it will not loosen for a long time after being assembled. It is easy to use safe drilling and tapping to complete the operation in one go.
The head of the stainless steel hexagonal drill tail wire is hexagonal, making it easy to tighten with tools such as wrenches. One of its major features is the "drill tail", which has a drill like design at the end of the screw.

Stainless steel material has good corrosion resistance and is suitable for use in environments with high rust prevention requirements, such as outdoor facilities and metal connections in humid environments. When in use, it can directly drill and tap on thin sheet materials, with a fast installation process that does not require pre drilling, effectively improving work efficiency.
