Blue Point Chain Drive Wrenches

[ericg]

Does anyone know the difference between the JWS3 and the JWF2 chain drive wrenches from Blue Point?
In case anyone is interested, there are two listings on Ebay

JWT1 = 1/4" drive
JWF2 = 3/8" drive
JWS3 = 3/4" drive (according to ebay add, seems more likely that it's 1/2 drive)

here's an old GJ thread w/ some info:

Thank you notlob. I saw the Ebay description said 3/4" drive but I thought it had to be a mistake. I did not think that this design wrench could take the torque of a 3/4" ratchet.

JWS3 is the 1/2. Also made in wrench sets, SAE and Metric

Snapmom, was there ever a 3/4" drive model? If so, do you know the catalog number?

I have not seen one in 3/4 dr.. I have not seen these in a cat. Most of them get over Torqued and are hard to turn., you should not use one on a air wrench.

Snapmom, I have one of the 1/4" JWT1 wrenches. I can turn it easily with a ratchet attached but it can only be turned by hand up to a certain point. Does that mean that the wrench was overtorqued?

I doubt if it is.
