查询词典 sheet metal

1 Self-threading or sheet metal screws may be used if threads are not stripped when the screw is tightened with a torque of 3.39 N·m (30 lb·in) and if the part or the assembly supported by the screw withstands for 1 min a force equal to four times the mass of the part or assembly, applied in a direction coincident with the axis of the screw.

测试方法：用3.39N.m（30lb.in）的扭力扭紧螺丝，并在装配表面的螺丝轴向施加于四倍于装配物重量，螺蚊应不受破坏。本文由tinson2008在安规网发表，如果提示附件不存在，点我进入备份站下载！
