1. The characteristics of the Cup Head Square Neck Bolts are that the head is made into a semi-round ball, a square neck is made under the head, and a square hole is also made correspondingly on the connected parts connected with such bolts. When the bolt is inserted into the connecting piece and then screwed on the nut, the bolt will not rotate due to the square neck. Its head is relatively smooth, and it is not easy to hook other objects. 2. Cup Head Square Neck Bolts is mainly used for connecting parts due to structural limitations are not suitable for hex bolts or bolts are required to have a smooth exposed part of the occasion. Such as the feet of agricultural machinery, wall panels and other places. The bolt is divided into two kinds according to the head size: ordinary and large half round head. The head of the large Cup Head Square Neck Bolts is straight and the diameter is large, but its thickness is slightly thin. This kind of bolt is mostly used in trucks, barges, iron and wood looms, and other wooden structural parts, because the head support surface is large, it is not easy to fall into the wooden connector.
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.
The T-bolt can be directly placed into the aluminum profile groove, and it can automatically position and lock during installation. It is often used in conjunction with flange nuts and is a standard matching connector for installing corner pieces. It can be selected and used according to the width of the profile groove and different series of profiles.
1. Tire wire anchor is a kind of fastener often encountered in daily life, mainly used for fixing. 2. Application: Tire wire anchors are usually used in heavy-load facilities with high tension and shear forces. They 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. Spring washer can play a good anti-loosening and anti-vibration effect; 2. Mechanical equipment: spring washer is widely used in various mechanical equipment, such as bearings, bushings, screws, nuts and other connection parts, play the role of anti-loosening, shock absorption, sealing and so on. 3. Electronic products: In electronic equipment, spring washer is used to fix components and lines to prevent loosening and improve the reliability and stability of the equipment. 4. Auto parts: Spring gaskets are also widely used in auto parts, such as engines, transmissions, suspension systems, etc., which play a role in shock absorption, sealing, fixing and so on. 5. Household goods: In furniture, household appliances and other household goods, spring washer is used to fix parts, prevent noise, improve comfort and so on.

1.Hex washer head tapping screws with inserts are a common fastener, which is characterized by a hex head and an insert (washer). This design allows the screw to better distribute pressure during tightening, preventing the screw from loosening, while also protecting the surface of the connected parts. 2. Wide application: Hex washer head tapping screws with inserts have been widely used in many fields due to their unique design and excellent performance. Whether in home decoration, machinery manufacturing, electronic products or construction projects, they can play an important role.
1. Transmission function: The rack can convert rotational motion into linear motion. This conversion is crucial in many mechanical devices, such as machine tools, automotive steering systems, etc. 2. Positioning function: In some special machinery and equipment, it is necessary to move objects up and down along a straight line, and the rack can play a positioning role. The vertical teeth on the rack can keep the machine stable during movement and ensure that it can move up or down in a straight line 3. Support and reinforcement function: Tooth strips play a role in supporting weight and strengthening the firmness at the intersection of the upright and horizontal beams of furniture. It is similar to wooden components in architecture, which can enhance the overall stability of furniture In summary, dental strips have different roles in different fields. In the field of machinery, it is mainly responsible for transmission, positioning, and control; In the field of furniture, it plays multiple roles of support, reinforcement, and decoration.
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.
1.hexagon socket bolts ISO 7380 are widely used both indoors and outdoors. Outdoor applications are mostly for building installations, bridges and roads, and power facilities; indoor applications are mostly for mechanical equipment, medical equipment, and electronic equipment. 2.When hexagon socket bolts ISO 7380 are used in electronic equipment, medical equipment, and other places, stainless steel hexagon socket bolts ISO 7380 are generally selected because the surface color of stainless steel is more beautiful and the corrosion resistance is better, which can keep the machine beautiful for a long time. If it is a mechanical equipment with large vibration, it is recommended to choose high-strength hexagonal bolts.
Rivet nuts are also called pull rivet nuts, pull caps, and instant pull caps. They are used in the fastening of various metal plates, pipes and other manufacturing industries. They are currently widely used in the assembly of electromechanical and light industrial products such as automobiles, aviation, railways, refrigeration, elevators, switches, instruments, furniture, and decoration. They are developed to solve the shortcomings of easy melting of welding nuts on metal sheets and thin tubes, easy welding deformation of base materials, and easy slipping of tapped internal threads. It does not require tapping internal threads, does not require welding nuts, has a strong riveting efficiency, and is easy to use.
The head of a hex flange bolt consists of two parts: the hexagonal head and the flange face. Its “support area to stress area ratio” is larger than that of a regular hexagonal head bolt, so this type of bolt can withstand higher pre tightening forces and has better anti loosening performance. Therefore, it is widely used in products such as automotive engines and heavy machinery. Hexagonal head bolts with holes and grooves can be mechanically locked to prevent loosening during use.
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. Metal-frame anchor are mainly used for expansion anchors of doors and windows. The product is mainly composed of expansion tube screw taper nut.It can firmly fix machines, doors and windows, structural parts, equipment or various appliances on walls, bases or concrete foundations. 2.
