The nut is a kind of fastening component, which is often used with a screw or a bolt. The common nut is mostly internal thread, and the bolt is fastened to the workpiece. The inner and outer nut are mainly used for the conversion of the internal and external threaded connection, one end has an external thread and one end has an internal thread. One end of the external thread is connected with the internally threaded pipe or the large diameter pipe, and one end of the internal thread is connected with the small diameter pipe, and the internal and external thread connection can be converted by the internal and external thread threads, or the pipe diameter can be reduced.
Precautions for the use of internal and external nut: The inner and outer nut are installed on the crossbar. The counters must be designed with a countersunk head to avoid cracking and uneven joint surface. The inner and outer teeth are installed at the end margins with a minimum distance of 5mm or more.
When installing the internal and external nut of the table, the nut must be clamped through the nut and then forced into the pre-drilled hole with a wrench from the upper screw. Install the table into the table. After fixing the screws, use a wrench to loosen the nut. After exiting, the screws can be removed, and the internal fasteners can be used to fix the various fixtures. Install the inner and outer nut and complete the table. After the whole process, the desktop will be completed, and only the cabinet below will be completed.
