22、1380 (#6)-40 right hand thread, long. MS21260-7RH Indicates - Terminal, 0.3750 (3/8)-24 right hand thread. 2. Dimensions are in inches. 3. Remove burrs and sharp edges. (See MIL-DTL-781.) 4. Interpret drawing in accordance with ASME Y14.5M. 5. In the event of a conflict between the text of this docu

23、ment and the references cited herein, the text of this document takes precedence. 6. Unless otherwise specified, issues of reference documents are those in effect at the time of solicitation. 7. Interchangeability relationship: MS21260 parts can universally replace the canceled AN669 and NAS650 part

24、s identified by the same dash number; but the canceled AN669 and NAS650 parts cannot replace the superseding MS21260 parts.

25、e inactive for new design. 9. Cutter radius mark, which is used as a clip slot alignment indicator, must be present on this surface. 10. During fabrication of the clip slot groove, operation of the cutter shall be maintained for the length of the terminal shank until engagement of the wrenching shou

26、lder surface occurs (see note 9). Depending upon the part tolerance conditions, the cutter radius marks may or may not appear on shank surface and shall not be cause for rejection. 11. Locking clip slot (dimension G) is optional for sizes -12 and above. 12. Marking: Complete MS part number, indented

27、. Use two faces if required. For terminal sizes -2 through -5, use basic part number only, example, MS21260.
