Product Description:
 

The eye nut is a part that closely connects the mechanical equipment. Through the inner thread, the ring nut and screw of the same specification can be connected together. The ring nut is often used in conjunction with the external thread column to lift various equipment, such as molds, chassis, motors, etc.

The ring screw is generally not surface treatment, but according to the requirements, can be galvanized passivation, chrome plating and other surface treatment, and according to GB5267-85 provisions.
After electrogalvanizing, the chemical composition and mechanical properties of the material should be tested in accordance with GB699. During routine inspection, the grain size test may not be advanced, and the grain size test method shall be prescribed by YB27. Thread inspection is carried out with thread gauges and smooth limit gauges or universal gauges.

The ring should be scrapped when visible deformation occurs.

When lifting, accompanied by an increase in acceleration or impact, you must choose a smaller load than the table above.

When lifting at 45°, measures such as sinking holes should be added to make the supporting surface of the bolt or nut closely stick with the mating part. Secondly, an appropriate washer is added so that the direction of the two rings is in the same plane. The error (deflection) of this combination should be within 5 degrees from the plane containing the axis.

For the purpose of increasing mechanical properties, when special steel and other materials are used and heat treated, the ductility becomes smaller, and it is easy to break before overloading and ring deformation, which is dangerous.

 
Applications

Carbon steel is a common metal material with a range of advantages:
1. High strength: carbon steel has excellent strength characteristics and can withstand large external forces and pressures. This makes carbon steel widely used in many engineering fields, such as construction, automotive manufacturing, and aerospace.
 

2. Good wear resistance: carbon steel has high wear resistance and can resist wear and scratches. This makes carbon steel ideal for manufacturing tools, machine parts and industrial equipment.
 

3. Strong plasticity: carbon steel is easy to process and form, and can be plastic deformed + through cold working +, hot working and forging processes. This plasticity makes carbon steel suitable for the manufacture of a wide variety of complex shapes and structures.
 

4. Price economy: Compared with other metal materials, the production cost of carbon steel is relatively low, so the price is relatively economical. This gives carbon steel a competitive advantage in large-scale industrial applications.

 
Galvanising is a surface treatment technique of plating a layer of zinc on the surface of metals, alloys or other materials to provide a beautiful and rust-resistant appearance. The colour of zinc after galvanising is silver-white, and the colour after passivation of galvanising can be white, coloured, army green, etc.
