NOTES: UNLESS OTHERWISE SPECIFIED
[1] “B” diameter and minor diameter of thread to be concentric within .003 FIM.
2. When parent materia 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
orNational 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 insert length shown
only. For non standard lengths (see part number coding) “D and E” must change accordingly.
