Small Yellow Plastic Expansion Plug Pipe Anchor Wall Plug Screw Nylon Expansion

Plastic expansion wire is a type of connector used to secure objects.
It is mainly made of plastic material. The principle is to use the expansion characteristics to achieve the purpose of fastening. When in use, insert the expansion wire into the pre drilled hole. When the screw is screwed into the expansion wire, the expansion wire will expand outward and tightly clamp onto the hole wall, which can firmly fix the screw and be used to fix objects such as lamps, pendants, bathroom equipment, etc. on walls or other installation surfaces.
Plastic expansion wire is usually composed of a plastic expansion sleeve and a self tapping screw that matches it. Plastic expansion sleeves are generally tubular in shape, with some parts having teeth or special structures such as fish shaped, straight through angled, etc., and a hole in the center for screws to pass through. Self tapping screws have sharp heads and threads.
 
-Principle: Insert the plastic sleeve of the plastic expansion wire into the pre drilled hole, and then screw in the self tapping screw. During the process of screwing in the screw, the plastic sleeve will expand inside the hole, thereby tightly fitting with the hole wall, generating friction and fastening force, and achieving the purpose of fixing the object to the wall or other materials.
 
characteristic
 
-Lightweight: Compared to metal expansion wires, it is significantly lighter in weight, making it easier to handle and install.
 
-Corrosion resistance: It can be used normally in harsh environments such as humidity, acidity, and alkalinity.
 
-Good insulation: can effectively prevent current leakage, ensure personal safety and normal operation of equipment.
 
-Easy installation: The operation is relatively simple, without the need for complex tools and techniques, and the installation efficiency is high.
 
-Low cost: The materials and production process are relatively simple, and the price is relatively affordable.
 
Application scenarios
 
-Home decoration: used to fix lightweight items such as curtain rods, towel racks, decorative paintings, and storage racks.
 
-In the field of architecture, it is possible to install door and window frames, fix electrical conduits, and fix insulation boards.
 
-Electronic appliances: widely used in fixing electrical enclosures, installing circuit boards, and other aspects.
 
-Other fields: It can also be used in manual fields such as toy and model making to achieve the fixation of components.
