How to use:The new American-style core expansion nail only needs to make a 6mm hole on the ground or wall. The depth is the same as that of the expansion nail. Put the expansion nail into the hole and hammer the head of the expansion nail with a hammer. The tail of the core nail will expand during the hammering process. The nail will be tightly stuck in the casing and will not be pulled out. The use process saves time and effort, and is more beautiful than the pull-out screw. ① Drill a hole in the wall according to the size requirements; ②Insert the expansion screw through the fixed object into the hole; ③Hit the iron nail to expand the inside.

Hollow wall anchor bolts, also known as hollow wall anchors or hollow expansion screws, are mainly used in hollow walls, gypsum boards, fiberboards, plastic boards, wooden boards and other walls. They are light load anchor bolts. The heads and nuts at both ends are of two types: “welded” and “integrated”. They can be directly installed with an electric screwdriver or pulled with special tools. Installation method: 1. The teeth on the head of the casing can be embedded in the hollow substrate, which can effectively prevent the casing from rotating in the hole during installation. 2. After installation, the expansion arm is opened behind the hollow substrate to form a large radius and large area of contact, providing a reliable anchoring effect. 3. The matching screws can be easily removed, and the mounting parts can be repeatedly disassembled and assembled without affecting the anchoring effect. 4. Ordinary flat-blade or cross screwdrivers can be used for installation. If special installation tools are used, it can be more suitable for large-scale professional use occasions.

Screws are used to connect two objects. Generally, the head of the screw will protrude above the surface of the connected object, making the surface uneven. Countersunk screws can sink below the surface to make the surface flat. Hard objects need to drill countersunk holes at the corresponding position of the countersunk head. In short, the countersunk head means that the head of the screw can keep the surface flat after installation. And wood screws are used to screw into wood for connection or fastening.
