Reference only: the drawing and its process spec govern. How to read this
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 NASM5258. SpecLok only lists an equivalent when a manufacturer or government document states it.
Possible NASM form, to verify: MS5258 / NASM5258. If a conversion exists, NASM is the converted form of the MS standard with an identical part number (e.g. MS90353U Notice 1). Not every MS has a NASM successor: verify the NASM document exists; the part may still be stocked as MS. MS90353U Notice 1: canceled and superseded by NASM90353, part numbers identical (everyspec) ↗
