Skidmore Verification of TC Bolts
Skidmore Verification of TC Bolts
(OP)
TC Bolts - AISC RCSC Code and ICC Code requirements for Not Slip Critical
Do TC bolts that are not called on plans as "SC" have to be checked for tension calibration with a Wilhelm Skidmore.
The Code reads, "a tension calibrator shall be used where bolts are to be installed in pretensioned and slip-critical joints"

Also, my understanding (RCSC section 9.3) is that the only difference between PT and SC, pre-installation verification, installation, and inspection requirements is that the faying surfaces meet the specified criteria.

In theory, the fastener assembly should be tested in a skidmore to verify that it's producing the proper tension.
I think a strict reading of the RCSC document would even say that assemblies utilizing DTI washers need to be calibrated via skidmore to verify they're producing the desired tension.
IMO, the way the code reads does not limit skidmore calibration to torque wrenches only.
