Scope
This study addresses the adequacy of sockets, wrenches, and torque adapters conforming to AS954 to wrench 12 point fasteners with wrenching configurations conforming to AS870C. Reported wrenching problems with smaller sizes are investigated through examining the combined tolerances on the fasteners and wrenches, conducting torque testing on typical high strength lock nuts. Possible solutions to correct these wrenching problems are presented.
Rationale
AIR1936A has been reaffirmed to comply with the SAE five-year review policy.

Issuing Committee
The SAE EG-1B Aerospace Hand Tool Committee addresses all facets of aerospace hand tools and tool kits in of support equipment-design, maintenance, and in-service experience. It focuses on support equipment and facilities related to gas turbine engine testing, balancing, engine accessory testing, inspection, packaging, handling, and transportability. High performance hand tools for aerospace applications are also addressed by EG-1B. The group is comprised of government, original equipment manufacturers, and users dedicated to creating, preparing and maintaining all relevant specifications, standards and requirements for aerospace propulsion system support equipment.

* 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.
