How to handle the surface of the eye nut?
Sep 14, 2017

The eye nut is used to link the parts of the mechanical equipment, so as to achieve the hanging, lifting, suspension and other operations. It works by taking advantage of the screw and screw threads at the lower part of the eye nut and connecting them with the same thread. The suspension nut is connected with the threaded column, so as to easily lift equipment, machinery, etc. with different specifications, type and weight.

eye nut refers to the nut and bolt or screw screw together, used for fastening parts, all manufacturing machinery must use an original. The hanging eye nut is a common hang for engineering. Below the nut with a screw thread, according to the different specifications, drilling, using screw fixation. The eye nut is a piece of machinery that is closely connected. It can be joined by the inner thread, the same specifications, the rings, the nuts and the screws.

The surface treatment of the eye nut is usually divided into electroplating and heat treatment. After plating is completed, oxygen treatment shall be carried out, and the mechanical properties and chemical composition of the relevant materials shall be tested in accordance with the GB699 regulations. The rings screw industry does not have the relevant provisions to carry out surface treatment, but it can be galvanized, passivation and so on.

How to handle the surface of the eye nut?:

Do not carry on the surface treatment to the hanging screw bolt, but according to the request, may carry on galvanization, passivation, chrome plating and so on surface processing, and according to the GB5267-85 regulation. After galvanizing, oxygen treatment should be carried out immediately. The test method for chemical composition and mechanical properties of materials shall be provided in accordance with GB699. The conventional test can be done without advanced grain size test, and the test method of grain size is according to the regulation of YB27. Screw thread gauges and smooth limit gauges or universal gauges are used for thread inspection.
