Nominal diameters. Blank cells: not stated in the documents we hold; take them from the standard. The shank for -6 is not settled: 1/64 in over nominal gives 0.203 in, but the distributor catalogue (checked on the printed page) lists 0.219 in for NAS1241 and NAS1242 -6 (the -4 and -5 rows, 0.140 and 0.172, are 1/64 in over). Confirm the shank against the standard.

Notes from the standard
- The shank for -6 is not settled: 1/64 in over nominal gives 0.203 in, but the distributor catalogue (checked on the printed page) lists 0.219 in for NAS1241 and NAS1242 -6 (the -4 and -5 rows, 0.140 and 0.172, are 1/64 in over). Confirm the shank against the standard.
- Repair rivet for MS20426: oversize shank for a hole that has been opened up.
- A standard and an oversize rivet of the same size have the same head.
- Whether an oversize repair is acceptable at all is a question for the SRM or approved data.
- Part number format as commonly written; check the standard for the exact format.
