Scope
This specification covers metric aircraft quality spacers for use as positioners for tubes, flat washers for use as load spreaders, galling protection of adjacent surfaces and or material compatibility, and key or tab washers for use as locks for bolts, nuts, and screws.
Rationale
Delete MIL-STD-105 sampling requirements and extensively revise Section 4 (Quality Assurance Provisions) to acceptance based on zero defectives, update FPI and MPI references, revise classification “MAJOR A” to “MAJOR B” based on acceptance quality requirements, revise military packing requirements to MIL-STD-2072-1, general update of references, and general editorial revisions.

* Redlines comparisons are available for those standards
listed in the Revision History that contain a radio button. A
redline comparison of the current version against a revision is
accomplished by selecting the radio button next to the standard and
then selecting 'compare'. At this time, Redline versions only exist
for some AMS standards. SAE will continue to add redline versioning
with ongoing updates to SAE MOBILUS.
