Machine meter screw also known as set screw, stop screw, jacking wire.
The cross groove of the plum groove in the machine meter screw, the word groove, is also the slotted machine meter screw.
The product is made of H62 copper, which is formed by cold heading and then rubbed teeth, and then the surface is treated with anti-oxidation treatment or bright nickel plating treatment.
Blackening is a common means of chemical surface treatment, the principle is to make the metal surface produce a layer of oxide film, in order to isolate the air, to achieve the purpose of rust.
The nickel coating belongs to the negative polarity coating for the iron matrix.
Because of its high porosity, it is necessary to use copper-plated layer as the bottom layer or multi-layer nickel plating.
The nickel coating deposited from ordinary nickel plating solution is not bright, but easy to polish.
A specular glossy nickel layer can be obtained by using certain brighteners.
A process by which a layer of nickel is deposited on the surface of a ferrous or nonferrous metal product by electrochemical action.
Can be used as a surface coating, but mainly used for chrome plating base, prevent corrosion, increase wear resistance, gloss and aesthetic.
Widely used in machines, instruments, instruments, medical equipment, household appliances and other manufacturing industries.
