FW: Structural Bolt Torquing Question

[Subject Prev][Subject Next][Thread Prev][Thread Next]

The answer is that nobody specifies torque.  The engineer should however specify the tension by referencing the "Specification for Structural Joints Using ASTM A325 or A490 Bolts".  This is commonly done from the structural notes or in the specifications.  The installation is also subject to special inspection.

Subject: Structural Bolt Torquing Question

Excuse me for what is probably an obvious question for those of you who
deal with these connections on a regular basis:

Who normally specifies the required bolt torque for a slip-critical
connection? The bolt supplier, steel fabricator or the engineer? Or is
it some other party?
