I would like to ask about the margin for high-strength bolts
Thread Content
Dear friends passing by: I have a question to ask. What percentage of surplus should be provided for high-strength bolts used in steel structures during actual supply? If the design institute specifies a certain number of bolts, in practice, when purchasing and supplying them, it is necessary to take into account the corresponding losses as well as the quantity required for slip resistance tests. So, what is this margin? Are there any corresponding standard requirements for support? Thank you!
