China Nut, also known as standard parts in the market. It is a kind of mechanical parts used for fastener connection, and it is widely used. The characteristics of fasteners: a wide variety of specifications, different performance and uses, and a high degree of standardization, serialization, and generalization. Therefore, some people call a type of fasteners that have national (industry)...

①Inspection of China Nut; visually inspect the surface quality of the bolts. Any burrs left by machining must be removed and sharp edges must be rounded.② Manual degreasing; ensure that there is no grease on the surface of the substrate.③Soak and remove oil; put the bolts in alkaline water and boil to remove the surface oil.④Pickling: In order to prevent the alkaline degreasing solution from...

　　1. China Stud Supplier introduces that the surface of stainless steel screws adheres to organic juices (such as melons, vegetables, noodle soup, sputum, etc.), organic acids will be formed under the action of water and oxygen, and organic acids will corrode metal surfaces.　　　　 2. In humid air, the adhesion of dust or dissimilar metal particles and the condensate of stainless steel screws...

　　 Stud Manufacturer is divided into many processes when making high-strength bolts, namely cold drawing-spheroidizing annealing-mechanical dephosphorization-pickling-cold drawing-cold forging forming-thread processing-heat treatment and finally to inspection. Each step of the high-strength bolt is very important and indispensable. Take the cold forging process as an example. Under normal...

The most important meaning of China Fasteners hardness is to resist the friction during assembly or the role in mechanical applications. For thread forming and thread cutting self-tapping screws, because it uses the internal extrusion or tapping from the mating hole Thread, so obviously, its hardness must be higher than the hardness of the mating assembly. If this is not the case, the...
