Specification
| Item | Value |
|---|---|
| Type | Blind rivet, with locking collar |
| Status | Cross-only card: the partner numbers, evidence ranked, and no sizes. No source states the unit of the size digits, so each number carries the NAS1738 partner it pairs with instead of a size. |
Part numbers
Every number seen in the cross data with the NAS1738 partner it pairs with, evidence in brackets (listing = distributor listing, NSN = federal NSN record). No size is shown: no source states the unit of the size digits.

From a measured hole or stack to the code
- Hole and stack. No hole or grip table is printed (not given by the standard). The digits follow the NAS partner: diameter n/32 in, and grip code n holds stacks up to n/16 in; the minimum of each code is not given by the standard.
If a segment is missing
- Without the standard number the codes cannot be read: grip code 04 is 4.78–6.35 mm on ASNA0077/0078, 5.56–7.16 mm on ASNA0026/0027, 5.59–7.14 mm on ASNA0081/0082.
- All five digits are needed: 1 diameter digit, 2 grip digits and 2 material/finish digits; a shorter number cannot be read.
What each code means
| Part | Meaning |
|---|---|
| Format | ASNA0064-<dash> |
| Example | ASNA0064-40311 — Pairs with NAS1738E4-3 (distributor listing). No size is given: no source states the unit of the size digits. |
Notes
- Part number: ASNA0064, a dash, then a diameter digit, two grip digits and two material or finish digits.
- Material and finish suffixes seen: 30 = NAS letter C (stainless), 31 = CW (stainless, cadmium plated), 20 = M (Monel), 21 = MW (Monel with cadmium W, by analogy). Others are not explained by our sources.
- The unit of the size digits is not stated by any source, so this card gives the partner number and no size. Do not size a hole from this card; use the partner's data sheet.
