What is the relationship between the specifications and use of the rivet screw?
The specifications of the rivet screw are of great concern to everyone. This product should be carefully maintained during use. It can be used as a fixing part in many machines and can play a variety of functions. The specifications of the rivet screw should be consulted before buying this problem. Knowing the knowledge of the part is also a self-improvement. So, what is the specification and use of the rivet screw?
The rivet screw is a stud that is turned by a lathe in the rivet stud industry. Its material is generally stainless steel and carbon steel. The stainless steel is divided into stainless steel 304 and stainless steel 410, as well as easy-cut iron carbon steel. The rivet screw is a fastener component used on sheet metal. The rivet screw is derived from the special hardware parts produced by PEM/TEXRON and other companies in the United States for the telecommunications industry, sheet metal industry, electronic appliances and other products. The domestically produced rivet screws are all produced with reference to the PEM standard, and the shape has a round head. And hexagonal head two.
The rivet screws are usually used in clothing, footwear and other industries. They need to be riveted again for heavy workpiece joints. They are often non-removable structures. Semi-hollow rivet screws are the most widely used, and the beam mouth (small diameter tail) is used. The manufacture of hard wire material can penetrate the steel plate with a thickness of 0.5mm without pre-holes. The rivet screw can not be bent and deformed. It is widely used in password boxes, suitcases and military bags. The hollow nails (semi-hollow rivet screws) are soft. Wire manufacturing, generally requires no cracking after riveting. There are many types. At present, some of the above-mentioned shafts of toys have begun to be replaced by semi-hollow nails or sub-nails, which can greatly reduce production costs.
The specifications of the rivet screw can be divided into five types: round head rivet screw FHFHSFHAFH4TFHTFHS, hexagonal rivet screw NFHNFHS extrusion screw KFE thick head rivet screw HFHHFHSHFHB5, countersunk head rivet screw CHACHCCFHACFHC. When using the rivet screw, the user needs to use the type of the rivet screw according to the workpiece to be effective.
The semi-circular head rivet screws are mainly used for riveting applications with large lateral loads and are the most widely used. The flat-cone head rivet screw is resistant to corrosion due to the hypertrophy of the nail head, and is often used for rugged applications such as hull and boiler water tanks. The countersunk head and 1200 countersunk head rivet screws are mainly used for riveting applications where the surface must be smooth and with little load. Semi-recessed head, 1200 semi-recessed head rivet screws are mainly used for riveting applications where the surface must be smooth and with little load.
It can be seen that many people pay attention to the specifications of the rivet screws. Its knowledge points are not even clear to the professionals. Reading the instructions is an effective way for us to learn and apply this standard. Therefore, the knowledge of the parts needs to be known by the purchasing personnel. The procurement process can reduce a lot of unnecessary communication, and the parts can not be used normally.
