Standard blind rivet (NAS1398/NAS1399 wiredraw)
NAS1398 / NAS1399 wiredraw locked-spindle blind rivet: for metal; not for a composite blind side.
- Shear 30-75 ksi
- Access Blind (one-sided)
- Diameters 1/8 to 1/4"
- Materials Aluminum, Monel
- Lead-time risk Low
Blind (one-sided), pulled-stem blind rivet: “Pulling head pulls stem in and blind head forms against blind sheet.” (Cherry CA-1005 (CherryLOCK), p.12, Wiredraw Installation Sequence)
- Shear
- 30-75 ksi
- Blind bulb
- standard
- Install
- One-side install
- Diameters
- 1/8, 5/32, 3/16, 1/4"
- Lead-time risk (SpecLok assessment)
- Low
Typical applications
- ·Metal structure with one-side access
Strengths
- +NAS standard part (NAS1398/NAS1399, procurement spec NAS1400)
Trade-offs
- −MIL-HDBK-17-3F C-32 calls for a large blind-side footprint on composite substructure
- −Removal is by drilling: "drill away the lock", then "Drill nearly through the head of the rivet" (CA-1005 Rivet Removal)
Also called pull rivet, NAS1398/NAS1399, self-plugging rivet. P/N: NAS1398 (universal head) / NAS1399 (countersunk head) · e.g. NAS1398B = CR2263
Datasheet strength: Wiredraw CherryLOCK ultimate shear strength: 30,000 psi (5056 aluminum / 7075 aluminum), 38,000 psi (2017 aluminum / 7075 aluminum), 75,000 psi (Monel / Monel); procurement spec NAS1400: Cherry CA-1005.

Cherry CA-1005 (CherryLOCK catalog, covers wiredraw NAS1398/NAS1399), Rivet Removal
- “In thick material remove the lock by driving out the rivet stem, using a pin punch.” Cherry CA-1005 (CherryLOCK), p.25, Rivet Removal ↗
- “If the rivets have been installed in thin sheets, driving out the locked stem may damage the sheets. It is recommended that the stem be center punched first and a small center drill be used to provide a guide for a larger drill on top of the rivet stem. The larger drill can then be used to drill away the lock. Finally, use a pin punch to drive out the stem.” Cherry CA-1005 (CherryLOCK), p.25, Rivet Removal ↗
- “Drill nearly through the head of the rivet, using a drill the same size as the rivet shank. Do not drill completely through rivet head.” Cherry CA-1005 (CherryLOCK), p.25, Rivet Removal ↗
- “Break off rivet head, using a pin punch as a pry.” Cherry CA-1005 (CherryLOCK), p.25, Rivet Removal ↗
- “Drive out the remaining rivet shank with a pin punch having a diameter equal to the rivet shank.” Cherry CA-1005 (CherryLOCK), p.25, Rivet Removal ↗
Cautions
- “CAUTION: Never drill completely through the rivet sleeve to remove a rivet as this will tend to enlarge the hole.” Cherry CA-1005 (CherryLOCK), p.25, Rivet Removal ↗
None of the removal procedures on file gives a composite-specific removal caution. The Monogram specs address composite at the hole instead: holes "reasonably round and free from burrs (metallic structure) and delamination (graphite/epoxy type structure)" (MBF2003 §5.1).
