Set of 3 Large T-Nuts for Chuck Jaws (3/4" X 10 threaded bolt holes)

Description

I purchased this set of three steel chuck jaw T-nuts from a aircraft manufacturing company shutting the plant down about a year ago.  These T-nuts have some slight surface rust on them from storing them in unheated storage for a year.  See pictures.  I don't know what chuck/jaws these fit.  Accordingly I have taken lots of measurements, as posted in the pics, to assist you in determining if they will fit your chuck/jaws.
The center to center bolt distance is approx. 60mm or 2.363".
These T-nuts accept a 3/4" X 10 coarse thread bolt.  One of the bolt holes has some slightly galled threads, but a 3/4" bolt screws in fine.  I have discounted the set because of this.   I don't accept returns, so please make sure it fits your chuck/jaws before you purchase these T-nuts.  If you need additional measurements, please let me know.  I can mic the measurements, if need be, to get more precise measurements.  I am offering free shipping anywhere in the the continental U.S. via USPS.  No international shipping.
