Zhuocheng High Pressure Series Blind Sealing Plug For Automotive

Hexagon socket head screws are used for fastening. They are commonly used in machinery. They mainly have the advantages of easy fastening, disassembly and not easy to slide. They are divided into carbon steel and stainless steel according to material. This screw is often vibrated and shaken when installed on the machine, so some Allen screws may loosen. In order to avoid this phenomenon, we need to adopt some anti loosening treatment. 1 - add a suitable spring washer between the hexagon socket screw and the workpiece. 2. Drop resistant glue dispensing shall be made at the end of the thread of the inner hexagon screw. 3. If the socket head cap screw is used in a place that does not need to be disassembled, the screw can be welded in the installation position after the screw is installed

Hex head bolts is a type of fastener consisting of a head and a screw (a cylinder with external threads) that is fitted with a nut for fastening two parts with through-holes,it divided into carbon steel bolts and stainless steel bolts according to the material,Hex head bolt are commonly used in different area and mainly have the advantages of easy fastening.Performance grade: carbon steel: grade 8.8/10.9/12.9, stainless steel A2-50/A4-70/80.  The bolts of grade 8.8 and above are made of low carbon alloy steel or medium carbon steel and subjected to heat treatment (quenching and tempering). They are called high-strength bolts, and the rest are called ordinary bolts.

Hexagon socket countersunk head bolt ISO10642/ DIN7991,similar to national standard GB70.3. The shape of the bolt head is concial. Generally, the opening angle is 90.The inside of the head is hexagonal polygon. ISO10642 hexagon socket countersunk head bolt is basically the same as the substrate surface after installation Flat, which saves space and plays the role of aesthetic decoration, has been widely used.Performance grade: carbon steel: grade 8.8/10.9/12.9, stainless steel A2-50/A4-70/80. surface treatment:carbon steel surface treatment is generally boiled black, galvanized, non electrolytic zinc sheet coating, thick galvanized vzd and thick galvanizedZinc plus sealing (zsml), zinc nickel coating silver (znshl), zinc nickel coating black (zhbh)

Lock nut is a nut which widely used in machinery and other industries, the working principle of lock nut is to use the friction between the nut and the bolt for self-locking, in some important occasions we will take some anti-loosening measures to ensure the reliability of the nut locking,the higher interaction force between the lock nut and the meshing thread of the bolt,the effect will be better.Performance grade: carbon steel: grade 4/8/10/12, stainless steel A2-50/A4-70/80, etc,Standard:DIN; GB; JIS;ISO;BS;ANSI ,Material:Carbon steel,Stainless steel.

Generally, the lifting ring is made of Q235 material, and weldable low alloy steel can also be used. Through numerical control cutting or photoelectric cutting process, the lifting ring hole is made of drilling machine process. In the lifting industry, hooks and rings are common tools. The lifting ring series includes: long ring, pear ring, ring, child and mother ring, butterfly buckle and high-strength ring chain. The lifting ring is forged with high-quality alloy steel and heat treated for overall quenching and tempering. It can be connected and hoisted separately or made. 1. The main ring used to form chain slings, wire rope slings and fiber slings should adopt long rings, and circular rings can be used in other occasions.2. The connecting ring must be a long ring 3. It is not allowed to re-use the defective lifting lugs after repair welding.4. The lifting rings on the combined parts of lifting slings and riggings shall be inspected regularly according to the requirements of the combined parts.
