A reed nut is a common type of fastener that works based on the properties of reeds. A reed nut usually consists of one or more reeds and a nut. Their primary function is to provide preload in threaded connections and to prevent loosening.
A reed is a flexible piece of metal, commonly made of stainless steel, spring steel, etc. The reeds in a reed nut are usually curved in shape, and the spacing between them allows the reeds to move relatively freely. When the nut is tightened, the reeds are compressed, generating an elastic force that creates a tight connection between the nut and the bolt. The operation of a reed nut can be divided into two stages: preloading and locking. In the preload stage, when the nut begins to tighten, the reed is compressed and begins to deform elastically. This elastic deformation allows the reed nut to provide a certain amount of preload, preventing the threaded connection from loosening during use.    

Dacromet technology is being used in the automotive industry.
1. Anti-corrosion of medium and small takeup racks, connecting parts, exposed parts, and fasteners on the chassis of all kinds of lower-strength vehicles, such as all kinds of steel takeup racks, bolts (including riding bolts, wheel bolts, etc.), nuts, etc. The sea has accurately revised the use of Dacromet coating anti-corrosion for fasteners ≥10.9 on the automobile, if Dacromet coating does not have lower corrosion resistance, and it may be possible to guarantee non-hydrogen hard. Steel is pickling war electroplating and other processes have the damage of exploding hydrogen hard, although it may be possible to remove hydrogen through heat treatment, it is very easy to fully sweep. The coating process of dacromet does not require pickling activation, nor does it guide the electrochemical reaction explosion of hydrogen evolution, which prevents the emergence of hydrogen hardening.
2. Anti-corrosion of metal parts in the thermal environment around the effect, such as heat insulation board, exhaust pipe, collector, cylinder head, and other whole parts. The passivation film on the surface of the conservative galvanized layer will be damaged when it is arranged at 70 ° C, and the corrosion resistance will slowly fall sharply, while the curing temperature of the Dallol coating is arranged at 300 ° C, the chromate loose compound in the coating does not contain crystallization fire, and the coating is easily damaged under the lower temperature, indicating a poor anti-corrosion instinct. The whole part treated with the dacromet process is used for a short time at 250℃, which is almost stable and has strong corrosion resistance.
3. Anti-corrosion of all kinds of elastic parts on the loaded car, such as ring hoop, semi-circular clamp, spring, plate spring, etc. The strength of the whole part of the hardness of the central supply is lower, the electroplating analysis of explosive hydrogens, such as hydrogen is not sufficient, and the dynamic load between the ages of simple explosive tear or corrosion fatigue will give the car to stop driving wear to the safety of hidden dangers, more is to deal with the loaded car, its business environment is harsh, so the surface treatment of those parts of the central supply is also comparable, The Dacron coating has lower corrosion resistance and lower weather resistance, which is very consistent with the surface treatment of the whole car parts.
4. Anti-corrosion of all kinds of pipe and cavity components on the car, such as exhaust pipes and mufflers that receive the effect. If the whole piece is taken and electroplated, due to the construction limitation of the whole shape of the whole piece, the dead coating is not symmetrical, and it may explode the leakage plating, which will make the corrosion resistance of the parts fall slowly and sharply, and the instinctive service life of the whole car will be curbed. The method of Dacro process picking and dipping does not keep the problem of coating ability and depth ability in the electroplating process, and Dacro treatment liquid has poor permeability, and it can also produce a good protective film in the thinly cut cross-contact holes, which is especially suitable for the anti-corrosion of the whole car of pipe and cavity purity. Some of the assembly pieces are being disassembled to go well and are also suitable for detached-Dacromet handling. In addition, Dacromet coating is not affected by all kinds of oils, antifreeze, scrubber, and other chemical products, chemical resistance, and weather resistance are also very good, so Dacromet is in line with the anti-corrosion of the chassis of the car and the whole parts of the car.
