I would like to know what thread the bolts are that hold the Parma handle together.
It measures close to 7/64" in diam.

They are 4-40UNC-2A

The two on the top are .875 long and the one on the bottom is .75 long.

Number 4 screws are .112 Diameter and the 40 is the threads per inch.
The 2 is the class of fit and the A means external thread.
