This standard covers the design, performance, and test requirements for high strength, thin wall, commercial sockets, universal sockets, and box wrenches used for the attachment and detachment of metric spline drive, high strength, and high temperature aircraft fasteners. Inclusion of dimensional data in this standard is not intended to imply that all of the products described herein are stock production sizes. Consumers are requested to consult with manufacturers concerning lists of stock production sizes. This standard is based on, but not limited to, the following external spline wrenching system:
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.
This recommended practice covers the dimensions of an inside splined driver-wrench adapter, envelope of the housing-wrench reaction, the mechanical method of adapting the driver-wrench adapter to the wrench adapter driven end, and the housing-wrench reaction to the holder-counter torque.
