The materials used for Hexagon Socket Head Bolt are different, and the hardness is also different. If the top surface of Hexagon Socket Head Bolt is quenched, then when we choose Hexagon Socket Head Bolt, we must consider the shape of the screw.
The compression force of Hexagon Socket Head Bolt is the smallest of slotted screws and the largest of square head screws. The inner Hexagon Socket Head Bolt is centered. The cone-end screws are generally suitable for low-strength parts. Hexagon Socket Head Bolt is used to increase transmission. Load capacity.
Both flat-end screws and female-end screws are suitable for machines with high hardness or frequent position adjustment; long cylindrical end screws are suitable for tubular shafts to transmit large loads, but there should be a device to prevent the screws from loosening during use .
When we use the Hexagon Socket Head Bolt from weigao China Fasteners Suppliers , we should use it according to the above method.

　　China Fasteners steel parts are blackened, and some are also called blue.
　　The principle is to quickly oxidize the surface of steel products to form a dense oxide film protective layer.
　　Blackening treatments are now commonly used by traditional alkaline heating blackening and later normal temperature blackening.
　　Normal temperature blackening process is mainly completed by the following process steps:
1) Cleaning; 2) Degreasing: the workpiece must be completely immersed in the degreasing solution; the concentration of the degreasing solution is 12-14, the processing time is 10-30min, and it shakes up and down several times every 3-5 minutes. Degreased powder; 3) Water washing; 4) Pickling: pickling solution concentration ph value 2-4, processing time 5-10min; 5) water washing; 6) blackening: pool liquid concentration ph value 2.5-3.5, processing time 10- 12min; 7) Wash with water; 8) Blow dry; 9) Grease.
　　Full Threaded Stud's blackening process has the following advantages: 1. Blackening is safe without electricity, and alkaline high temperature blackening requires 100% electricity. 2. Improve work efficiency: it takes 1-2 minutes in total. 3. The blackening cost is low, the equipment is simple, and the operation is convenient; the blackening time is strictly controlled. 4. Strong process adaptability: solved the problem that nodular cast iron can not blacken. Blackened for wear resistance and rust prevention.

Hexagon Flange Bolt refers to the Hexagon Flange Bolt that does not need to correspond to the standard, that is, the Hexagon Flange Bolt without strict standard specifications. The manufacturing cost of the general non-standard Hexagon Flange Bolt is higher than the standard Hexagon Flange Bolt.
Hexagon Flange Bolt is different for each mold. The parts in contact with the product glue level on the mold are generally non-standard parts. The main ones are the front mold, the rear mold, and the insert. It can also be said that apart from screws, spouts, thimble, aprons, springs, and mold blanks, almost all are non-standard Hexagon Flange Bolt. If you want to purchase non-standard Hexagon Flange Bolt, you should generally provide design input such as technical specifications, drawings and drafts, and the supplier will evaluate the difficulty of achieving the non-standard Hexagon Flange Bolt and preliminary estimate the production of non-standard Hexagon Flange Bolt Cost, batch, production cycle, etc.
The big difference between Hexagon Flange Bolt and non-standard Hexagon Flange Bolt is whether there is standardization. Standard Hexagon Flange Bolt has strict standards set by the country in terms of structure, size, painting, marking and other aspects. Parts), common standard Threaded Rods And Eye Bolts have threaded parts, keys, pins, rolling bearings and so on.

Threaded Rods And Eye Bolts can be used in that way? In fact, Threaded Rods And Eye Bolts are a type of mechanical parts that are used for fastening connections and are widely used. All kinds of fasteners can be seen on various machinery, equipment, vehicles, ships, railways, bridges, buildings, structures, tools, instruments, meters and supplies. It is characterized by a large variety, different performance and uses, and a high degree of standardization, serialization, and generalization. Therefore, some people refer to a class of fasteners that have existing national standards as standard fasteners, or Threaded Rods And Eye Bolts for short. Fasteners are the most widely used mechanical basic parts. As China joined the WTO in 2001 and entered the ranks of major international trade countries.
China's Hexagon Flange Bolt products are exported to countries all over the world, and fastener products from all over the world are constantly pouring into the Chinese market. Fasteners, as one of China's products with a large import and export volume, achieve international integration, and have important practical and strategic significance to promote Chinese fastener enterprises to the world and promote fastener enterprises to participate in international cooperation and competition . Due to the specific product specifications, dimensions, tolerances, weight, performance, surface conditions, marking methods, and acceptance inspection, marking and packaging of each fastener specific product requirements.

In our life and production, we often see Hexagon Flange Bolt, do you know what are the reasons for the appearance of non-standard screws?

Non-standard screws refer to threads that do not meet China's standards, other countries' standards, or international standards. The emergence of non-standard screws is due to environmental constraints. In some environments, it is not suitable to use standard screws, and only non-standard screws can be used. Second, because of corporate behavior and the development of the enterprise, non-standard screws are cheaper and more quality than standard screws. it is good.

Zhejiang Weigao Standard Parts Co., Ltd. specializes in the production of various non-standard special-shaped fasteners. For 9 years, it has focused on CNC lathe processing, exquisite technology, and the factory pass rate is as high as 99.9%. It mainly produces non-standard screws, stainless steel cylindrical pins, positioning pins, Fasteners such as pillars support customized drawings and samples. Our Threaded Rods And Eye Bolts have also won the favor and praise of consumers. If you are interested, please come and leave us a message.
