There are many varieties of rings and rigging used in life. For example, eyebolts and eyebolts are well-known rings and rigging products. Ring screw, also known as the ring screw, eyebolt, ring nut, etc., are very different from the rings in the sports. It is also called the ring, which belongs to the mold fastener. Ring screw products are widely used: ports, power, steel, shipbuilding, petrochemical, mining, railways, construction and so on. If you are interested in eyebolts, you may wish to follow me to learn about it!
Ring screw introduction
Ring screw, overall forging, normalized + oxide scale removal; forgings without defects; ring screw hardness test, hardness value HRB67 ~ 95. Force crown ring screw grade strength is 12.9.
It must be installed vertically and on the plane of the workpiece. The joint surface should be flat and tight. Must be adjusted to the stretching direction to avoid contact with sharp objects.
Ring screw, test load is 2.5 times the workload, and 20,000 fatigue tests under 1.5 times the workload. Ring screw, in line with ASME B30.26 standard requirements. The alloy steel is produced with high reference to the German RUD WBG type, and is exported to Europe and the United States in large quantities, and passes the G80 standard inspection. The material is higher in tension than domestic rings and provides tensile test reports. Professionals are required to operate, and please refer to the instructions for use. When connecting with a spreader, keep the connection between the spreader and the lifting ring freely. Professionals should conduct regular safety inspections. The maximum working load is 30T and the inch thread can be customized.

Ring screw use
Ring screw is widely used in ports, shipbuilding, railways, construction, plastic machinery, industrial control, pipeline auxiliary facilities, sea rescue, airport construction, aerospace, stadiums and other important industries and infrastructure construction machinery and equipment.
7 Precautions for Use of Eye Screws
1. The user must be trained to use it, in order to use the product correctly and ensure safety;
2. For different occasions and application scenarios, select the correct type, grade, and length of eyebolt;
3. Before use, check carefully to see if there is any damage. If so, replace it immediately.
4. Turn it into close contact with the supporting surface and do not allow the tool plate to be tight.
5. Different types of eyebolts, lifting direction should be within the force direction. For example: rings screws have national standards, American standards, etc., to ensure that it is within its force range;
6. The maximum lifting weight is the rated load and cannot be overloaded, otherwise it will have serious consequences;
7. If 10% of the diameter of the worn-out interface is found during use, stop using it. If it is used forcibly, safety accidents may occur.
Editor's summary: The above is the introduction of the ring screw specifications and the use of the eyebolts with the seven major precautions. I hope to be able to help those who have this need!

Smco1:5 magnet is also named Smco5. Prorated with metallic samarium, cobalt and metallic praseodymium, are firstly those roughcasts with different properties and grades after series technology processing from melting, milling, and pressing to sintering in order. The (BH)max range is from 16 to 25, maximum working temperature 250 ℃. The physical character and ductibility of Smco5 is better than Sm2Co17, so Smco5 is slightly easier to be machined thin thickness disc or ring wall and complex shapes while Sm2Co17 is more brittle. Magnetization magnetic field of Smco5 is lower than Sm2Co17's. In general, Smco5 can be magnetized saturated by 4000Guass magnetic field. However, magnetizing Sm2Co17 with high Hcj value need more than 6000guass magnetic field. These days, prices of rare earth material improved significantly, and the level of rare earth material around the magnet is up to 40%. For these reasons, the price of Smco5 is more expensive than Sm2Co17. According to different using circumstance, customers can choose SmCo5 or Sm2Co17 reasonably.
