The invention provides a salt mist test nut-type component placing device, which belongs to the technical field of the operation, and solves the problems that traditional salt mist test nut-type component placing device cannot conform to the stipulation of item 2 of VII of GB/T10125-1997 and the test result obtained by utilizing a fixing device to fix the nut-type components to perform the salt mist test cannot meet the requirement. The salt mist test nut-type component placing device comprises a plurality of placing rods and a support with a horizontal positioning plate; and one end of the placing rod is fixedly connected with the support, and an angle between the axis of the placing rod and the horizontal positioning plate is 15 to 30 DEG. The placing device and a work piece which is placed by utilizing the placing device conform to the stipulation of VII of GB/T10125-1997. The device only comprises one support and a plurality of placing rods, so that the device has advantages of simpleness in structure and convenience in production. Nuts are directly placed on the placing rods, so that the device has an advantage that a sample is convenient to fetch.
