During the installation of blind bolts, the standard parts are inserted into the climbing structure of special riveting tools, and then they are put into the punching or punching machine which has been prepared for a long time. When the special tool is started, the claw of the organization is crawled to hold the nail core and pull it into the bolt body. The edge of the core axially pushes the bolt wall and fills the hole. In addition, the pin core produces a load-bearing head or ball at the end of the bolt to fix the plates together. When the tensile load on the core exceeds the load necessary for the deformation of the bolt body, the core will be broken at the predetermined position; the blind bolts of non structural, semi-structural and organizational lantern cap rivets are all made of carbon steel, stainless steel plate and aluminum. Blind bolts range in diameter from 3 / 32 inch to 3 / 4 inch. At the present stage, many customers have specified larger diameter standard parts - 1 / 2 inch and 5 / 8 inch - and the riveting scope is also wider; the development and design of bolts with thin, soft and brittle materials has attracted more and more attention. Avdel's avibulb XT and avinox XT bolts are typical. This 1 / 4 inch blind bolt riveting range is very wide, which is suitable for cars, household appliances, truck trailers, semi hollow rivet mechanical equipment and renewable resources and other fields; the riveting category of 1.5mm and 8mm can be covered by two standard parts.
