The Role Of DIN 603 Bolts

Posted by abyihui on Feb 10, 2020 in News

DIN 603 bolts are our common fastener products. They are used with bolts, studs or other threaded workpieces for attachment and fixing. In general, the strength of the bolts selected in the design is higher than that of the corresponding high-strength DIN 933 bolts to ensure that the bolts have a longer life than the DIN 933 bolts when used together. When fasteners are removed and replaced in this way, the cost of replacing DIN 933 bolts will be cheaper and more convenient.

Currently, many power generation equipment and vehicles such as airplanes, cars, trains and ships are developing rapidly. Therefore, our high-strength DIN 933 bolts and other locking parts need to adapt to the rapid development trend in order to achieve greater development. High-strength bolts are mainly used to connect some important mechanical equipment, especially for repeated disassembly and assembly. Various assembly methods require very high Square Bolt. The thread is also very important. The surface quality and manufacturing accuracy of the thread directly affect the safety factor of the equipment used.

The Choice Of DIN 603 Bolts Is Critical

Posted by abyihui on Jan 13, 2020 in News

DIN 603 bolts look inconspicuous, but they play a large role, with high strength and strong shear resistance, ensuring reliable connection and fixing. At present, many people ignore it. The phenomenon of using bolts arbitrarily is quite serious, which causes frequent failures of construction machinery.

In actual maintenance operations, when some maintenance personnel found that these bolts were damaged or missing, some standard bolts could not be found for a while, and some were free to take other bolts instead, and some of them were replaced by their own processing. The later use of construction machinery leaves a hidden trouble. Some parts need to use “small-pitch” “fine-tightening self-tightening” bolts, copper bolts, and copper-plated bolts, but ordinary bolts are used instead, resulting in the bolts becoming loose and difficult to disassemble.

Some DIN 603 bolts will have defects such as stretching and deformation after use. Some technical requirements require that new bolts must be replaced after disassembly and assembly. Because maintenance personnel do not understand these conditions, it is easy to reuse unqualified bolts many times. Causes mechanical failure or accident. Therefore, when repairing construction machinery, when DIN 603 bolts are damaged or missing, replace the bolts that meet the requirements in a timely manner, and do not use the bolts arbitrarily.



Development Requirements Of Din 603 Bolts

Posted by abyihui on Jan 6, 2020 in News

Many companies have appeared in the DIN 603 bolt industry, and these companies are constantly innovating and developing. As far as the whole industry is concerned, these companies are not very innovative, but because they follow the old rules, they have a flat record. Judging from the development of today’s market, there are always many specific requirements and changes in these growing markets. Many customers have strict requirements on DIN 603 bolts.

The production capacity of our low-grade products has been selling at a good price after many sales prices. However, because of its limited capacity, the rise is very slow. These phenomena have completely changed the ability to enhance independent innovation. The DIN 603 bolt industry has unreasonable and unscientific phenomena in many aspects such as development ideas, project investment, growth methods, resource utilization, environmental protection, production mechanism, quality assurance, economic operation, and enterprise management.

For enterprises, some problems are very serious, and exist and develop. During the 11th Five-Year Plan period, enterprises need to adhere to a scientific outlook on development, effectively change these unfavorable factors, improve the quality of the enterprise, and establish good corporate innovation. This is one of the important factors to strengthen the DIN 603 bolt industry.



Din 603 Bolt Installation Specifications

When we assemble DIN 603 bolted joints, the nut side of the round table should face the side of the washer with chamfer. In general, when assembling large hexagon head DIN 603 bolted joints, the lower beam of the bolt head has a slope, and the side of the lower beam of the bolt head should face the bolt head.

When installing DIN 603 bolts, the construction personnel should strictly forbid the forcible penetration of the bolts (here, hammering)

Bolt manufacturer: Other specifications for DIN 603 bolt installation

If it cannot penetrate freely, use a reamer to trim the hole. After trimming, the diameter of the hole should be less than 1.2 times the diameter of the bolt. When filling holes, in order to prevent iron filings from falling into the overlapping seams of the board, all bolts around the hinges and the joints in front of the holes should be tightened first and checked for firmness so that the boards can overlap tightly before operation. One thing to note here is that it is strictly prohibited to use gas cutting to ream. Gas cutting and reaming are prone to occur at the site and require special supervision.



Widespread Application Of DIN 603 Bolts

The Use Of Stainless Steel DIN 603 Bolts

Posted by abyihui on Nov 25, 2019 in News

When you need to buy stainless steel DIN 603 bolts, it is usually best to know them as much as possible. This is important because it makes it easier for you to understand the expectations you can get from it. There are many people who decide which DIN 603 bolts to use and how to use them based on heresy. However, this can result in significant loss of money and customer goodwill, especially if you plan to use DIN 603 bolts for long periods of time.

For stainless steel DIN 603 bolts, you may overlook many facts, but you should consider these facts when deciding to use them. Some of the most important ones include:

Stainless steel DIN 603 bolts will still corrode
One of the main selling points of stainless steel hex nuts, stainless steel hex set screws and other similar products is that they do not corrode. However, the truth is that this quality usually depends on other variables. To prevent corrosion, stainless steel typically reacts with oxygen to form an invisible layer that prevents the underlying material from coming into contact with water, oxygen or other corrosive materials. When DIN 603 bolts that do not form this layer are exposed to low oxygen levels, the metal can easily corrode when exposed to chemicals that can cause corrosion.



DIN 603 Bolt Installation Specification Requirements

No matter what is the production process of DIN 603 bolts, the safety inspection of high-strength bolts, and finally the scientific storage and delivery to the on-site specification installation, I believe that all partners have a very detailed understanding of this! DIN 603 bolts As a kind of fastener, its production process is extremely strict, and the operation specifications in each link are relatively strict, but some small details are rarely made, which needs to be done and realized. The following small series will make some arrangements for some details.

Other specifications for DIN 603 bolt mounting

When we assemble a DIN 603 bolt coupling, the end face of the nut with a rounded end face should be opposite the chamfered end face of the washer. For larger hex head DIN 603 bolted pairs in the assembly, the bolt head under the chamfered side of the washer should face the bolt head. When installing high-strength bolts, the construction personnel should not force the bolts in (in this case, hammers, etc.). If it is not free to pass, the hole should be trimmed with a reamer. The maximum diameter of the hole after trimming should be less than 1.2 times the diameter of the bolt. When filling the hole, in order to prevent the iron filings from falling in the overlapping seam, tighten the bolts around the hole before the reaming, and check whether the bolt is firm, so that the laminated plate is fastened and fitted before use. One thing to note here is that it is strictly forbidden to use gas cutting and reaming. It is easier to use gas cutting and reaming on site, and special inspectors are needed.



Characteristics Of DIN 603 Bolts

1. Plating thickness of DIN 603 bolt

DIN 603 bolts are used in the electroplating process regardless of the barrel plating or the hanging plating process. In each batch of products, the thickness of the coating obtained by each fastener is different, that is, the distribution of the coating on the same fastener is also uneven. . For example, the thickness of the coating of the thread crest is thicker than the median diameter and the bottom of the tooth, and the thickness of the plating at both ends of the screw and the bolt is thicker than the middle, and is more remarkable as the length to diameter ratio increases. The same applies to the nut. Due to the shielding effect during the nut plating process, the thickness of the plating layer on the internal thread is very thin, and only the first fastener on both ends is thicker than the plating in the middle portion, which is equivalent to the hex wrench surface. thickness.

2. How to describe the plating thickness of a batch of DIN 603 bolts
In view of the non-uniformity of the thickness distribution of the DIN 603 bolt plating layer, four definitions of the coating thickness are cited in the standard, namely “nominal plating thickness”, “batch average thickness”, “partial thickness” and “effective plating thickness”. “Nominal plating thickness” means the nominal plating thickness of DIN 603 bolts and does not represent the actual plating thickness. The actual coating thickness of DIN 603 bolts is described by “effective plating thickness”. “Effective Coating Thickness” includes both “batch average thickness” and “local thickness”.



How To Choose DIN 603 Bolt

Posted by abyihui on Okt 29, 2019 in News

The purchase of the correct length of the DIN 603 bolt is a prerequisite for the user to use, the length of the screw sleeve will affect the use of the effect.

First, according to the needs of the use of the choice of the ordinary type DIN 603 bolt or lock type DIN 603 bolt. The locking type DIN 603 bolt is a special one or more rings of polygonal locking ring. It can lock the screw in the thread formed by the DIN 603 bolt installation. When it is shocked and impacted, it can be normally locked. The process performance of the device is good, and generally no ordinary case is used for ordinary DIN 603 bolts.

Second, according to the specifications of the screw to select the screw sleeve. DIN 603 bolts can be customized with suitable screw sleeves. The nominal diameter and pitch of the screws should be used when selecting. Then select the appropriate DIN 603 bolts according to the thread specifications and industry standards. Tell the DIN 603 bolt manufacturer these values, the manufacturer will match the corresponding length DIN 603 bolt according to the value, after installing the DIN 603 bolt and the threaded hole just fit. Specifically:

1. Determine how big the screws are and buy the DIN 603 bolts. The reason is simple: after installing the DIN 603 bolt, the original screw is used. DIN 603 bolts can be customized with suitable threaded sleeves.

2. Determine what the thread length of the screw is, or what the thread depth of the bottom hole is, the values ​​of the two are the same. This value determines the length of the DIN 603 bolt.



DIN 603 Bolts Are Widely Used

Posted by abyihui on Okt 16, 2019 in News

The DIN 603 bolts are used in a wide variety of applications: construction, mechanical fittings, vehicle ships, bridge tunnels, etc. Main shapes: semi-circular, square right angle, triangle, oblique triangle, etc.

In the processing of DIN 603 bolts, it is generally the case that the DIN 603 bolts are usually first ventilated and then bent by a bending machine. Diathermy is the heat treatment of the DIN 603 bolt from the outside to the inside, which is the heat treatment process before the metal forging. DIN 603 bolt diathermy can be selected with super-audio induction heating equipment.

DIN 603 bolts are widely used in construction and installation, mechanical parts connections, vehicle ships, bridge tunnels and other industries. Its main shape is semi-circular square right angle, triangle, oblique triangle and so on. DIN 603 bolts are indispensable parts of machinery. DIN 603 bolts generally pay attention to two aspects in operation, quality and operational safety.

Main safety technical measures: The size of the wrench using the adjustable wrench should match the size of the DIN 603 bolt. Do not use a small wrench to add the sleeve. Use a dead wrench for high-altitude work. If you use a spanner wrench, use a rope to secure it. When assembling steel components to DIN 603 bolts, it is strictly forbidden to insert the joint surface or the probe screw hole by hand. When the horn plate is taken, the fingers should be placed on both sides of the horn plate.

After the contact friction surface treatment, the specified anti-scratch coefficient requirements must be met. It is best to use high-strength bolts with matching nuts and washers. They should be carried out in accordance with the matching process and should not be interchanged.
