Abstract
A self-taping anticorrosive coupling screw comprises a screw head and a screw rod, and is characterized in that a drill bit is arranged at the front end of the screw rod, wherein the screw rod and the drill bit are formed by the connection of different materials. Due to the fact that the drill bit is arranged at the front end of the screw rod, the self-taping anticorrosive coupling screw can directly drill on a component to connect, and has the advantages ob being simple in structure, convenient to use and anticorrosive.
Description
Technical field
The utility model relates to link, specifically a kind of self tapping corrosion resistant attachment screw that is applicable to direct boring connection on connector element.
Background technique
It is to punch at two members first that common bolt connects, and then bolt is penetrated in the hole, and the termination that passes at bolt connects with nut.Owing to structural reason, above-mentioned common bolt is very inconvenient when connecting large-scale component.
Summary of the invention
The purpose of this utility model is for plain bolt defective in the use, proposes a kind of self tapping corrosion resistant attachment screw that directly connects in member boring.
The purpose of this utility model solves by following technical solution: a kind of self tapping corrosion resistant attachment screw, and it comprises screw head and screw rod, it is characterized in that screw front end is provided with drill bit, above-mentioned screw rod and drill bit adopt the material of unlike material to be formed by connecting.
Self tapping corrosion resistant attachment screw of the present utility model owing to be provided with drill bit at screw front end, can directly connect in member boring, simultaneously because drill bit adopts different materials with screw rod, has the characteristics of easy to use and corrosion resistant simple in structure.
Description of drawings
Fig. 1 is the structural representation of self tapping corrosion resistant attachment screw of the present utility model.
Embodiment
