Part numbers and lengths
Every part number of MS35265 Rev. C, by thread size, each with its own link.
.086-56 UNC-2A10 part numbers · tolerance +.00/-.03
Dash number from Table I selects thread size and length (1 to 119); no optional code letters on the sheet
(none)
Material: carbon steel, cadmium plated (the only material and finish)
Notes from the standard
Lengths are printed to two decimals (.12, .19, .31 ...); Table II gives the same lengths in millimetres (3.05, 4.83, 7.87 ...), recorded here as length_mm.
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.
Dash number 112 (.375-16, 1.25 long) prints like "122" in Table I of this scan; read as 112 by the sequential numbering and Table III of the sheet.
Sheet 2 (Table II) is the metric translation of Table I; sheet 3 (Table III) cross-references the cancelled MS35263, MS35267, MS35269 and AN500 (in part) dash numbers; not transcribed. Supersedes MS35263, MS35267, MS35269 and, in part, AN500, MS35361 and MS35366 (and Bureau of Ships BC.. designations; part of the list is illegible).
