Common ANSI B18.2.1 Bol

  We often say that ANSI B18.2.1 bolts are actually a type of fastener consisting of a screw and a head. This requires coordination with the nut to achieve the tightening effect. The conditions of use of ANSI B18.2.1 bolts are to fasten two parts with through holes so that the parts are fastened. This type of connection is called ANSI B18.2.1 bolt connection.

     As for screwing and fastening, of course, you can unscrew the nut from the ANSI B18.2.1 bolt to separate the two parts, so the ANSI B18.2.1 bolt connection is a detachable fastener. However, the threads of ANSI B18.2.1 bolts are fine-threaded so that the nuts can be tightened.
