The nose follows the maker, not the stock number: check the maker on the CoC or packaging.
Reference only: the drawing and its process spec govern. How to read this
Every size and maker in the NAS9305BH series →
Blind rivet, 100° flush head, oversize diameter
Dash numbers not decoded: SpecLok has no structured decoder for this series. Read them from the controlling spec.
Identical or approved-alternate part numbers, each with the document that states it.
No sourced equivalent on file for NAS9305BH-4-08. SpecLok only lists an equivalent when a manufacturer or government document states it.
CA-1015 Note 1: "X represents the diameter code, in 1/32" increments ... XX represents the grip code (two digits) in 1/16" increments". Example: NAS9301B-5-04 is a 5/32" diameter, 1/4" max grip fastener.

Same function, not interchangeable: needs engineering approval.

| Functional substituteneeds engineering approvalHowmet, "How to order Huck-Clinch® Blind Rivets", p.2 ↗Howmet: Huck-Clinch rivets "also meet NAS1686 procurement and specification and can be ordered as" NAS9305BH (H = internal lock) or NAS9305BNS (no lock preference), not as NAS9305B (Huck's 2010 tool catalog lists NAS9305B under HuckMAX, p.79, and NAS9305BH under HUCK-CLINCH, p.81). The document prints no HC-to-NAS table: HC3242 is read from its codes (324 oversize diameter, head 2 100° flush, aluminum sleeve, alloy steel spindle), so this needs engineering approval. Both number the diameter in 1/32 in. and the max grip in 1/16 in. (examples HC3242-5-04, NAS 9301 B H -4 -05).Dash numbers carried over: the cited document prints both part numbers with the same dash structure. |
