    Howmet, "How to order Huck-Clinch® Blind Rivets", p.2 ↗

    Howmet: Huck-Clinch rivets "also meet NAS1686 procurement and specification and can be ordered as" NAS9304BH (internal lock) or NAS9304BNS (no lock preference). The document prints no HC-to-NAS table: HC3243 is read from its codes (324 oversize diameter, head 3 protruding, aluminum sleeve, alloy steel spindle). Both number the diameter in 1/32 in. and the max grip in 1/16 in. (example HC3242-5-04).

    Dash numbers carried over: the cited document prints both part numbers with the same dash structure.

Related, not equivalents (other head, material or the procurement spec): CR3243

Each row is one National Stock Number and the part numbers DLA FLIS lists on it, as written there. A blank means FLIS lists no part in that series on the stock number, not that the size does not exist.

Reference numbers the Federal Logistics Information System records against the same National Stock Number. A supply-catalog cross-reference, not an engineering-approved interchangeability: confirm against the controlling drawing or spec before substituting. Only equivalents marked cited have a manufacturer or government document, linked with each.

NAS9301B to NAS9306B part numbers with an H or NS after the base (NAS9301BNS) carry a lock-type code and are grouped with the base, per Howmet, "How to order Huck-Clinch® Blind Rivets", p.2 ↗.
