Notes from the standard
- Threaded length approximately 2/3 L.
- Recess in accordance with MS9006.
- Dash numbers of sizes 3, 5, 7 and 9 are inactive for new design after 15 August 1974 (crossed out in Tables II and III).
- Supersedes AN545 in part. Steel cadmium plated screws of revision A and brass black oxide coated screws of revision B were cancelled in 1967 and 1968; Table IV of the standard gives their replacements.
- Part number: the MS number plus the dash number, for example MS35493-1.
