Service HotlineA rivet is a nail-shaped object used to connect two parts with a through hole and a cap at one end. It is mainly used in riveting to connect the riveted parts by its own deformation or interference.
Riveting products provide great convenience for the unilateral connection of sheet parts, fast and efficient connection without bulky installation tools, and produce reliable standard internal and external threads, achieve cold installation after surface treatment, no pollution, is welding Effective alternative to nuts. Main applications: Auto-body, seat belt systems, bumpers, airbag systems, etc. 1. One-way drawing connection 2. Build standard internal and external threads 3. General product range: M3-M124. Materials: Carbon Steel, Stainless Steel, Aluminum 5. High quality air tools - efficient, economical, lightweight and easy to operate. Use the same principle as hand rivet nuts.
The spring washer usually includes a washer body and a raised claw head punched and formed on the washer body. The spring washer is often placed between the bolt head of the bolt and the connected parts, wherein the raised claw head is connected to the part to be connected. The surfaces of the connecting parts are in contact, and the plane on the gasket body, opposite to the lifting direction of the raised claw head, is in contact with the bolt head. After the bolt head is tightened, the elastic reaction force generated by the raised claw head after flattening makes the The screwed threads are pressed tightly, and at the same time, the raised claw head is pressed against the bolt head and the supporting surface of the connected parts, which has the effect of preventing loosening. However, the traditional spring washer is a single-claw type. When tightening, the raised claw head will cause great damage to the surface of the connected parts, so it is not suitable for the anti-loosening treatment of parts with small surface hardness.
Principles of stainless steel screw material selection: The selection of stainless steel materials is mainly considered from the following five aspects. 1. Requirements on mechanical properties, especially strength, of stainless steel screw materials; 2. Requirements on corrosion resistance of materials by working conditions; 3. Heat resistance of materials by working temperature (high temperature strength, oxidation resistance) 4. Requirements for material processing performance in terms of production technology; 5. Other aspects such as weight, price, procurement and many other factors must be considered.
Hexagon head bolts are divided into two types: outer hexagon bolts and inner hexagon screws. According to the force mode of the connection, there are ordinary ones and those with reaming holes. The bolts used for reaming holes should be matched with the size of the holes and are used when receiving lateral force. According to the shape of the head, there are hexagonal head and round head. , square head, countersunk head, etc. Generally, the countersunk head is used in places where the surface is smooth and no protrusions are required after connection, because the countersunk head can be screwed into the part. The round head can also be screwed into the part. The tightening force of the square head can be Larger, but larger in size. Hexagons are the most commonly used. In addition, in order to meet the needs of locking after installation, there are holes in the head and holes in the rod. These holes can prevent the bolts from loosening when they are subjected to vibration.
