Notes from the standard
Lengths are printed to two decimals (.12, .19, .31 ...); Table II (sheet 2) gives the same lengths in millimetres (3.05, 4.83, 7.87 ...).
Thread per Screw-Thread Standards for Federal Services (Handbook H28). Full form threads extend to within two threads or less of the head bearing surface for lengths through 2.00 in (50.80 mm); longer screws have a minimum full form thread length of 1.50 in (38.10 mm).
The drilled hole is approximately at a right angle to the slot and may be permitted to break through the bottom of the slot. All burrs and sharp edges are removed.
For design feature purposes this standard takes precedence over the procurement documents referenced herein.
Sheet note 10: supersedes MS35264, MS35268, MS35270, BCCX1.2, BCCX1.3, BCCX1.6, BCCX1.9, BCCX2 and, in part, AN501, MS35361, MS35366, BCFX5, BCFX7 and BCHX2 (reference designations as printed; the scan is poor).
Interchangeability (Table III, sheet 3): screws covered by dash numbers in MS35264, MS35268, MS35270 and, in part, AN501 are canceled after 12 Nov 1964; the canceled screws cannot always replace the new ones and are used until existing stock is depleted. MS35264, MS35268 and MS35270 dash numbers are superseded by the same MS35266 dash number. "no replacement" = NR on the sheet. The AN501 suffix is printed without the AN501 prefix on the sheet; AN501 A516-8 is read from a blurred "A516-6/-8" line.
