Regarding the question of how fasteners are divided into two categories

2009-03-27View Original

Thread Content

A few days ago I posted a question asking about the two categories into which fasteners are divided; I’ve found the answer now, but I couldn’t locate the previous post, so I’m posting it again in the hope that it will be helpful to other students who also have questions about this topic! Fasteners are divided into two grades: commercial grade and special grade. The main difference between them lies in the inspection requirements, which are outlined in the fastener-related sections of the pipe flange standards HG20592 and HG20615. :)
