Drop-in equivalents

Identical or approved-alternate part numbers, each with the document that states it.

No sourced equivalent on file for HC3242-4-08. 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.

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.
