FAQs

Are my sockets for the S90EZ/GS91EZ interchangeable with the S-110EZ/GS-111EZ tools? Every tool?

The S-60EZA and S-61EZ are interchangeable. The S-90EZ and GS-91EZ are interchangeable and the S110EZ and GS-111EZ are interchangeable. All other sockets for the shear wrenches are specific to the models.

Are the same size sockets interchangeable between different tools?

Typically, the answer is no but there are exceptions.  The only interchangeable sockets for current model shear wrenches are between the GV-301ZA and the GVC-301EZ. The Older models like the S-60EZA share sockets with their newer models like the S-61EZ. The same is true for the S-90EZ and GS-91EZ as well as the S-110EZ and the GS-111EZ. There are a few TN tools that share sockets with each other such as the TN-20EZ and the TN-22EZ as well as the TN-30EZ and the TN-33EZ. The GNR series can share sockets with some of the TN tools. The GNR-31E, 51E, & 81E can use the TN-20EZ/22EZ bar sockets instead of impact sockets. The GNR-121E can use the bar sockets of the TN-24EZA and the GNR-211E can use the bar sockets of the TN-30EZ/33EZ. The GNR’s can also share impact sockets that have their correct drive size.

Does my shear wrench need to be calibrated?

No, shear wrenches do not have any settings for calibration. TC bolts are calibrated and come with mill certificates to prove calibration.
