Rivet screws are studs that are manufactured using lathes in the rivet stud industry; their materials generally include stainless steel, carbon steel, and copper. Copper materials can be either H59 copper or H62 copper. Stainless steel comes in types such as SUS304, SUS303, and also SUS302, etc. Carbon steel is generally referred to as malleable iron. It is an iron rod that is easy to turn. A rivet screw is a fastening product used on sheet metal. During use, a small hole must be made in the substrate; the rivet screw is inserted into this hole, and then a riveting device is used to apply even pressure parallel to the head of the screw. Since the head of the rivet screw features toothed patterns, when it is pressed in, the substrate deforms around it and engages with these toothed patterns, thereby forming a secure external thread. Standard rivet screws come in both metric and imperial standards, with thread profiles that are the same as those of regular fasteners. Advantages 1. High torque resistance ； 2. Easy to assemble – only simple riveting is required ； 3. Surface processing is safe and suitable for coated materials ； 4. Standardized specifications to meet various design requirements ； Application Technical Guide 1. Installation must be carried out through riveting, with the pressure applied depending on the dimensions of the sheet metal and screw heads. 2. The holes in the processed sheets must correspond to the values given in the table, and should be manufactured with a tolerance of 0–0.075 mm; punching is recommended. 3. When selecting screws, it is necessary to consider the thickness of the material being used as well as the requirements for the sheet material; for low-carbon steel sheets, the value should be less than 70RB, while for stainless steel sheets, it must be less than 80RB. 4. In the FH (FHS) series of products, the material used for FH is medium-carbon aluminum, which undergoes quenching and surface treatment. Users can order according to the models listed in the table as needed, or they can request custom fabrication.
