1.DIN912 hex socket screw, also known as hex socket cylindrical head screw, is a common fastener, widely used in various mechanical equipment and electronic products. The DIN912 hex screw features a cylindrical head with a hexagonal hole at the top that requires the use of an hex wrench to tighten or loosen. This design allows the screw to provide greater torque during installation, while also preventing the screw from loosening during use. 2. Widely used : Commonly used in medical device industry, wind power industry, wind power industry, office equipment industry, office equipment industry, electronics industry, communications industry, shipbuilding industry, etc
DIN929 welded hex nuts are mainly used in scenarios that require high-strength connections and special shaped connections. 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.
DIN125 gaskets are mainly used to connect two objects, fill gaps, and play a role in sealing, supporting, and fastening. It is widely used in various mechanical equipment, pipeline systems and other connections, with good sealing performance and mechanical strength.

The application scenarios of sheep eye hook sleeves mainly include home decoration, kitchen construction, door and window binding, and toy and gift binding. Sheep eye hook sleeve is commonly used in home decoration and kitchen construction, which can meet various hook needs and provide a firm fixing point. In addition, it can also be used for door and window binding or toy gift binding, providing reliable fixing effect.
1. Hex nuts are mainly used in conjunction with bolts or screws to achieve the connection and fastening of two or more parts. The design of hex nuts enables them to have good torque transmission capabilities and can withstand large axial and radial loads. 2. Characteristic: There must be enough operating space during installation. You can use an adjustable wrench, open-end wrench or glasses wrench during installation. All of the above wrenches require a large operating space. 3. Wide application: It is widely used and is characterized by its strong tightening force. Hex nuts cover almost all areas where fasteners are needed. For example: construction engineering, machinery manufacturing, electronic products and home repair, etc.
1. Sheep eye screws, also known as sheep eye, sheep eye rings, sheep eye nails, sheep eye screws, etc., are widely used in jewelry, toys, craft gifts, a variety of wooden handles and other hanging accessories, and is also one of the commonly used hardware accessories for architectural decoration. 2. Widely used : the eye bolt has the hanging function, which can be used to hang architectural ornaments under the suspended ceiling of cement precast board, wood board, gypsum board, decorative board or other plates; The eye bolt has large section diameter, long screw and thread length, and is safe and stable and not easy to loose when installed on the ceiling
DIN127 spring washers are mainly used in bolt connections, especially in bolt connections with a strength grade of 5.8 or below. Its main purpose is to prevent bolt loosening by increasing the axial rebound force to compensate for the loss of preload force caused by compression, thereby preventing the loosening of threaded connections.
Hexagonal embedded locking nut is a type of fastener that can lock threads. It is widely used in fields such as mechanical manufacturing, automotive manufacturing, and electronic equipment. In high-speed mechanical equipment, locking nuts can effectively prevent thread loosening and ensure the safe and stable operation of the equipment.
1. Determine bearing capacity: The diameter of the nut is directly related to its bearing capacity. Generally speaking, the larger the diameter, the stronger the load-bearing capacity of the nut. This means that when subjected to high loads, it is necessary to choose nuts with larger diameters 2. Impact on installation space: The diameter of the nut can also affect its installation space requirements. When designing mechanical structures, it is necessary to consider the diameter of the nut to ensure sufficient space for installation and operation. 3. Standardized production: The DIN934 standard specifies the diameter of nuts, which helps to achieve standardized production of nuts. Standardized production not only improves production efficiency, but also ensures the quality and interchangeability of nuts. The diameter parameter in DIN934 standard plays a key role in the application of nuts, which not only affects the function and performance of nuts, but also relates to the stability and safety of the entire mechanical structure.
1. Flange screw is a kind of fastener composed of two parts: hexagonal head and flange (the gasket under the hexagonal is fixed together with the hexagonal) and screw (cylinder with external thread), which needs to be matched with the nut for fastening and connecting two parts with through holes. 2. Hexagonal flange bolt is a particularly common industrial equipment used in industry, because it has the characteristics of accurate decoration and strong endurance, it has been widely used, it is widely used in road and railway Bridges, including industrial and civil construction, cranes, excavators and other heavy machinery
1. How to use：When using the wedge anchor, you need to first use an impact electric drill to drill a hole of the corresponding size on the fixed body, then install the bolt and expansion tube into the hole, and tighten the nut to expand the bolt, expansion tube, mounting piece and fixed body into one. 2. Characteristics: Wedge Anchors do not have high requirements for the depth and cleanliness of concrete cavities and are easy to install. 3. Application: Wedge anchors are usually used in heavy-duty facilities and are suitable for concrete and dense natural stone, metal structures, metal profiles, base plates, support plates, brackets, railings, windows, curtain walls, machines, beams, girders, brackets, etc.

1.The characteristic of slotted pan head tapping screw is that they can be used without matching nuts. Usually, the corresponding threads are “drilled, squeezed and pressed” out of the solid body through its own threads to make them fit closely with each other. 2. Wide application: Slotted pan head tapping screws are widely used in many industries due to their convenience and efficiency.In the installation and maintenance of power equipment, slotted pan head self-tapping screws can quickly fix various parts and improve work efficiency. In the field of building decoration, this screw is suitable for fixing gypsum boards, decorative lines, etc. Slotted pan head screws can also be used in industries such as mechanical equipment, digital products, household appliances and water conservancy projects.
