Taupa puipui omo

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.

In addition, DIN1587 hexagonal cap nuts are also suitable for various mechanical equipment to enhance their stability and anti loosening effect.

Drop in Anchor

1. Drop in Anchor is a kind of expansion bolt, Drop in Anchor thread is long and easy to install, usually used for heavy load facilities, so it is widely used, many industries can basically be used, generally play a fixed role, suitable for concrete and dense natural stone, metal structure, metal sheet, floor, support plate, bracket, railing and so on. 2. Widely used ‌ : the end of the pipe stretched into the hole of the tube plate by theDrop in Anchor rolls, resulting in continuous expansion of the inner wall of the tube, resulting in plastic deformation, the diameter of the tube increases, the tube head is completely fitted to the hole wall of the tube plate, and the tube plate is forced to produce elastic deformation. When the tube expander is removed, the elastic deformation of the tube plate wants to return to its original state, and the plastic deformation of the tube end can not be recovered, and the result is that the tube plate holds the tube end tightly, so as to achieve the purpose of sealing and firmly connecting the two.

DIN928 welded square nuts are widely used in multiple fields, including mechanical manufacturing, automotive industry, aerospace, photovoltaics, transportation, construction, and more. The characteristics of these application areas require high-strength and reliable fasteners, and DIN928 welded square nuts precisely meet these requirements. It can withstand high-strength tensile and shear forces, suitable for situations that require strong forces and vibrations. The design of the four corners provides better welding performance, making the connection more secure and reliable. It can be installed through welding or threaded connection, making installation simple and convenient. Suitable for various industrial fields, ensuring stability and reliability of connections.

DIN7980 spring washer

1. Preventing loosening: The main function of spring washers is to prevent loosening of fasteners (such as nuts and bolts) through their elasticity and oblique friction. When the nut is tightened, the spring washer is compressed, generating a reverse force that increases the friction between the nut and bolt, effectively preventing loosening 2. Reduce friction: Spring washers can also reduce friction between nuts and bolts, making fasteners less likely to loosen when subjected to vibration. This characteristic is particularly important for mechanical equipment that is frequently subjected to vibration or impact 3. Expand contact area: Although flat washers are mainly used to expand contact area and disperse pressure, spring washers can also play a similar role to some extent. Especially when the strength of the connected parts is low, using flat pads or flange bolts can increase the contact area, while spring washers can further prevent loosening 4. Special applications: In some special cases, the use of spring washers depends on specific engineering requirements.

DIN127 Fufulu Puna

DIN127 spring washers are mainly used in bolt connections, especially in bolt connections with a strength grade of 5.8 or below.

This type of nut is connected to the connector by welding and is suitable for situations where conventional bolt connections cannot be made, such as when the connector is too thin or irregularly shaped. The welding process is equivalent to turning two separate parts into a whole, melting the metal at high temperature, mixing it together, and then cooling it. An alloy is added in the middle, relying on molecular force, and its strength is generally greater than that of the parent material.

DIN6923 Fa'aauupegaina i nifo e tete'e slip Hex Flange Nut

1. Increase the contact surface and force area: One end of the hexagonal flange nut has a wide flange (i.e. flange surface), which increases the contact area between the nut and the workpiece. According to the principles of mechanics, the larger the force area, the smaller the pressure on the force surface, thereby improving the load-bearing capacity and stability of the nut. 2. Sealing: Due to the hexagonal flange nut having a flange surface fixed on one end of the nut body and a cap fixed on the other end, this design has good sealing performance during use, which can effectively prevent harmful substances such as rainwater, moisture, dust, etc. from entering the nut body, prevent the nut body from rusting, and thus extend its service life. 3. Wide application: Hexagonal flange nuts are widely used in various industrial and civilian fields. For example, they are commonly used in applications such as pipeline connections, stamped parts, and castings that require increased contact surface stability. In addition, hexagonal flange nuts are also used in heavy machinery, automotive engines, and other applications that require high preload force and good anti loosening performance.
