Always check ANSI B18 2.1 Stud bolts Dimensions and weight before buying material

ASME B18 2.1 Bolts is a threaded fastener with an external male thread requiring a matching pre-formed female thread such as a nut. It is invented to engage with the tool used to tighten them. Some bolt heads instead lock the bolt in place, so that it does not move and a tool is only required for the nut end. There are various types of ASME B18 2.1 Bolts such as ASME B18 2.1 carriage bolt, ASME B18 2.1 hex bolt, ASME B18 2.1 u-bolt, ASME B18 2.1 lag bolt, ASME B18 2.1 j-bolt, ASME B18 2.1 elevator, ASME B18 2.1 hanger bolt etc.  

ASME B18 2.1 Stud Bolts has a thread on full-lengths or at both ends. If washers are not used than it is has three components i.e. two nuts and stud. And if you use the washer it would become five. Sometimes with a larger size stud additional nuts are used for hydraulic tensioning. The ASME B18 2.1 Stud Bolts length should be enough to cover the entire nut plus 1.5 to 3 threads exposed.
