Anti corrosion treatment method of hexagon socket bolts surface In the production of hexagon socket bolts, one of the most important links is to carry out anti-corrosion treatment on the surface. You may ask "how to carry out anti-corrosion treatment?" in fact, different corrosion conditions lead to different anti-corrosion treatment methods. Today, we will briefly [...]
How is the bolt head and thread processed? The head of bolt is formed by cold upsetting plastic processing. Compared with the cutting process, the metal fiber (metal wire) is continuous along the product shape without cutting off in the middle. Therefore, the strength of the product is improved, especially the mechanical properties are excellent. [...]

Rotatable 360 deg. Link swivel range max. 180 deg. The ball bearing allows the ring [...]
Application of Ring Screw:Ring screw should be mainly used in port, shipbuilding, railway, construction, plastic machinery, industrial control, pipeline auxiliary equipment, marine rescue, Airport construction, aerospace, venues and other important industries as well as infrastructure engineering machinery and equipment. Cautions for using application of ring screw: 1. Users must be trained before they can use [...]
Generally, hanging ring bolts do not undergo surface treatment, but according to the requirements of use, they can be passivated by galvanizing, chromium plating and other surface treatment. Ring Bolts Surface Treatment Dehydrogenation should be carried out immediately after galvanizing. As a standard fastener, ring bolt is widely used in mechanical and electrical products. Its [...]
Eyebolts Technical Requirements Eyebolts shall be made of 20 or 25 steel (GB699). The eyebolts must be integrally forged. Forgings should be normalized and the scale removed. The grain size of the finished product should not be lower than Grade 5 (GB6394), and the forgings should not have over-burning or crack defects. In order to [...]
Eye bolts are widely used in ports, electric power, steel, shipbuilding, petrochemical, mining, railway, construction, metallurgical chemical, automobile manufacturing, plastic machinery, industrial control, highway, large-scale transportation, pipeline auxiliary, slope tunnel, well treatment Protection, marine assistance, offshore engineering, airport construction, bridges, aviation, aerospace, stadiums and other important industries as well as mechanical equipment for infrastructure projects.
