  The hanging ring screw is also a common small part of fasteners, and its hanging ring screw is made of warm quenching and forging. External thread length "H", the bolt is fixed with other parts, and the replacement must use the same quality grade of the bolt.

   

  The process of using eyebolts:

   

  Hanging ring screws are forged as a whole, and are normalized and cleared of oxidation; the forgings are free of overburning and cracking defects; hanging ring screws are tested for hardness, and the hardness value is HRB67-95. Hanging ring screws are used for vertical installation on the workpiece plane, and the joint surface is very flat and tight.

   

  The use of hanging ring screws:

   

  Hanging ring screw is mainly used in our life link role, its products are mainly used in ports, electric power, shipbuilding, petrochemical, mining, railroads, automobile manufacturing, plastic machinery, industrial control, highways, large transport, pipeline auxiliary, slope tunnels, shaft management protection, marine rescue, marine engineering, airport construction, aerospace, stadiums and other important industries and infrastructure projects of machinery and equipment.

   

  The specifications of the use of lifting ring screws:

   

  According to the standard to divide its different types and specifications, if the load points have 0.16 tons, 0.25 tons, 0.40 tons, 0.63 tons, 1 ton, 1.6 tons, 2.5 tons, 4 tons, 6.3 tons, 8 tons, 10 tons, 16 tons, 20 tons; according to the standard to have M8, M10, M12, M16, M20, M24, M30, M36, M42, M48, M56, M64. M48, M56, M64, M72×6, M80×6, M100×6.

   

  Some of the matters that need to be noted in the use of the specification of the hanging ring screws:

   

  1, the user must be trained before using the product, the main purpose is to be able to use the product correctly, to ensure safety;

   

  2, in different occasions, different application scenarios must be reasonable to choose the correct type, grade and length of the eyebolt, a reasonable choice of appropriate products;

   

  3、Each eyebolt must be carefully checked before use, check whether there is damage to the deformation, if there is damage to the deformation and other acts, to immediately replace;

   

  4、Hanging ring screws must be screwed to the support surface and close fit, do not allow the use of tools plate tight and ensure that the threads and threaded mouth with tight;

   

  5, different models of eyebolt screws, lifting direction should be designed in its force direction range, specific reference can be made to its standard, for example, eyebolt screws have a national standard, American standard and other different standards, and different material grades, so be sure to ensure that is within its force range;

   

  6, the maximum lifting weight of the eyebolt screw for the rated load, can not be used overload, otherwise, it will produce other serious consequences;

   

  7, if the eyebolt in the process of use found that it wear more than 10% of the diameter of the interface must stop using if you continue to force the use, it is easy to happen all kinds of safety accidents, so be sure to pay special attention.

   

  The use of eyebolts

  The eyebolt is a screw designed for lifting, and its main function is to lift the load in the field of hardware and machinery. According to the size of the specifications can carry the corresponding working load, which is convenient for machinery and equipment lifting without binding, that is, the installation of the lifting is convenient and fast.

   

  The thread specifications of eyebolts and other bolts vary and are generally divided into metric threads and inch threads. In order to clarify the use of specifications, the surface of the eyebolts is cast with thread specifications, maximum load-bearing and other parameters. As a lifting tool, the use and installation of eyebolts should be operated by professionals and strictly comply with the operating specifications.

   

  In addition to the above-mentioned eyebolts for lifting loads, there is also a kind of live knot eyebolt for small loads. Loose knot eyebolts have relatively small holes and tight pitches, which are suitable for lifting and traction of small and light equipment.
