本研究探讨了符合AS954的套筒、扳手和扭矩适配器是否适用于符合AS870C的扳手配置的12点紧固件。通过检查紧固件和扳手的组合公差，对典型的高强度锁紧螺母进行扭矩测试，对报告的较小尺寸的扳手问题进行了调查。提出了纠正这些棘手问题的可能解决方案。

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.
