NOTES: UNLESS OTHERWISE SPECIFIED
[1] “ B” diameter and minor diameter of thread to be concentric within .003 FIM.
2. When parent material surface is not flat or normal to axis of hole, provide a spotface for proper lockring entry.
[3] Thread as shown per MIL-S-8879 is prefered. Alternate thread per MIL-S-7742 class 3B or National class 3 is
applicable when specified by design activity.
4. Remove all burrs and sharp edges.
[5] “ D” minimum full thread depth and “ E” minimum drill depth are applicable for standard inser t length shown
only. For non standard lengths (see par t number coding) ” D” and “ E” must change accordingly.
