Notes from the standard
- Thread per MIL-S-7742. Add L at the end of the part number for lockwire holes.
- E carries printed tolerances (+.004, +.005, +.016) in cells spanning several rows; the exact rows are not clear in the listing, so they are not assigned. Take them from the standard.
- Cells printed once across several rows in the listing are repeated on each row they span.
