The tail of the drilling screw is in the shape of drilling tail or sharp tail, without auxiliary processing, can be directly drilled, tapped and locked on the setting material and basic material, greatly saving construction time. Compared with ordinary screws, its toughness and maintenance force is high, and it will not be loose after a long time after combination, and the operation is simple to use safe drilling and tapping once.Use: It is a kind of screw, mainly used in the steel structure of the color steel tile fixed can also be used for simple construction of thin plate fixed. It cannot be used for metal-metal bonding.Materials are iron, stainless steel two kinds of stainless steel is divided into a variety of materials.Models are: Φ4.2/ Φ4.8/ Φ5.5/ Φ6.3mm, the specific length can be agreed upon according to requirements.
