Bolts according to DIN 933 have constructive analogues - these are GOST 7798, GOST 7805, EN ISO 4017 (insignificant differences in turnkey size on some diameters), DIN 931 (the main difference is incomplete thread).

The hex head bolt is the most recognizable and common fastener. Of all the bolts, it is the bolt with full thread according to DIN 933 that is most often used in mechanical engineering, during assembly work, and the connection of various elements. It is found unchanged in all countries of the world and has not yielded to the leading positions for many years. This is possible due to the following advantages:

• Ease of use: the hexagonal shape of the head allows you to transmit a large torque, and not tear off the edges. Access possible from both top and side;

• attractive price-quality ratio;
• the widest size range: at present, it is possible to supply bolts from M2 to M72 in lengths from 3mm to 600mm. You can purchase bolts from GK TsKI from stock with a diameter from M 3 to 36;

• a large number of materials and coatings: bolts according to DIN 933 can be made of carbon steel and have the following strength classes: 4.6, 5.8, 8.8, 10.9, 12.9, from austenitic stainless and acid-resistant steels of various strength classes (the most common A2 / AISI304 / 08X18H10 and A4 / AISI316 / 10X17H13M2, brass, polyamide Carbon steel bolts are commercially available both uncoated and in various versions (the most common are galvanized and hot-dip galvanized).

Each strength class has its own values ​​of breaking loads. Bolts with a strength class of 8.8 and higher are called high-strength bolts.

Bolts can be mounted both in the body of a part, and they can connect several elements to each other. In this case, the bolt is usually used with a nut and washer. It is important to observe the tightening torque in order to achieve the maximum efficiency of the connection.

Bolt DIN 933 is a cylindrical rod equipped with a hex head. A distinctive feature of the product is the full thread. When choosing, you should carefully read the strength class of the product, the material of manufacture, as well as compliance with standards. You will find a high-quality galvanized bolt DIN 933 here - in the shop of the company "Uniform Metal" LLC.

Scope of use

The range of applications for this galvanized bolt is impressive. It is difficult to find a more popular product that is used in the construction industry. The product is actively used in manufacturing industries. For example, in mechanical engineering. In other words, bolts are used where the safety and strength of the entire structure depends on the reliability of fixation.

Details References

Below is the text of the standard for bolts with full thread and hex head DIN 933. The most relevant Russian standard is GOST 7798-70.

The most commonly used bolts that comply with this standard are:

• High strength without protective coatings, strength class 10.9.

September 1987

Hex bolts with thread up to the head
Thread from M1.6 to M52
Accuracy classes A and B

Hexagon head screws; Metric thread M 1.6 to M 52, product grades A and B

Compliant with DIN ISO 4017 / 09.87
Replaced edition from 12.83

The ISO 4017 standard shall be used instead, see comments. It should be taken into account,
that until 01.07.92 standard DIN 933 as amended on 09.87 will be withdrawn from circulation.

In the standard, all dimensions are indicated in millimeters.

1 area of ​​use

This standard contains requirements for hex bolts threaded up to the head, with metric coarse threads from M1.6 to M52 of accuracy class A with dimensions up to M24 and length ≤ 10 d, i.e. up to 150 mm, as well as for accuracy class B - with thread sizes over M24 or length> 10 d, i.e. over 150 mm. Bolts conforming to DIN 933 Part 1 are threaded up to approx. Head and standard lengths up to 200
mm.

In special cases, if instead of those given in this standard it is necessary to use other
requirements, for example other strength classes, these should be selected in the relevant standards.

2 Dimensions

Thread ends according to DIN 78-K, also permissible for non-chamfered bolts with thread dimensions ≤ M4.

Allowable bolt head shape:

k "- minimum height for gripping with a key (0.7 k min.)

These standards apply to metric hex head bolts with partial and full threads.

The main distinguishing feature of bolts manufactured according to the requirements of DIN 931 and DIN 933 is the different thread rolling area and different minimum and maximum length ranges.

Bolts made according to DIN 931 have partial threads up to 153 mm in length, with a total maximum bolt length of up to 950 mm.

Bolts according to DIN 933 have a thread rolled along the entire length of the rod, with the exception of the thread runaway area, which must be taken into account when calculating the length of the bolt in the joint. The maximum bolt length according to this standard is limited to 340 mm and the minimum 5 mm.

An analysis of the structural differences of bolts according to DIN 931 and DIN 933 shows that the former are preferable to use in cases where the thickness of the parts in the joint is not less than 18 mm, as well as in cases of through-joining of thick parts or using them as a tie for plates spread over a considerable distance. The predominant field of application is construction. Bolts in accordance with DIN 933, due to the minimum stipulated bolt length of 5 mm, can be used in fastening thin sheet materials, as well as in places where several parts are connected in series, each with a separate fixation using nuts. The predominant field of application is mechanical engineering.

Technical description to DIN 933

general description

The most popular in the world bolt DIN 933 is a cylindrical rod with a hex head. The bolt shank is fully threaded. These bolts are made from steels of various strength classes and can have various types of coatings. The DIN 933 standard corresponds to GOST 7798, GOST 7805, ISO 4017.

If we analyze the use of a bolt with a hexagonal head, it becomes obvious that the fastener is used in construction, as well as in mechanical engineering, and other manufacturing industries. They are used when connecting parts, nodes, planes to each other. The fact that the bolt is not simple, but, one might say, presentable, is evidenced by its compliance with GOST 7798-70, 7805-70, 15589-70, as well as DIN 558. And this list is completed by the international quality certification ISO 4017.

It would seem that it is an ordinary bolt, with an ordinary hex head, but it meets so many domestic and international standards. Also attracts metric values. Available in lengths from 5 to 340 millimeters with metric threads from M3 to M64.

Specifications DIN 933

This bolt is an excellent metal fastener, one might say, universal. Made from extra strong metals. Typically, strength classes such as 1.7709, 12.9, 10.9, 8.8, 5.6 are used. For the production of bolts, according to GOST, steels of grades A2, A5 are used. These are stainless steels that give the bolt extra strength and excellent corrosion resistance.

If this bolt is intended for fastening units and parts that will work in aggressive environments, additional processing is carried out. The fastener is coated with protective materials by applying a thin layer of zinc to the surface by electroplating or hot. Possible nickel plating of the bolt in electroplating baths. Thermal diffusion galvanizing is used, as well as chromating by galvanic method.

In special cases, hardware enterprises of the country carry out orders for the manufacture of a DIN 933 bolt from such strong and expensive metals as copper, brass, and aluminum. High-strength plastic is also used. All bolts of this type are fully threaded and can be used with the corresponding class 6 nuts.

Bolts DIN 933 6.8 strength class have a tensile strength, which is equal to the effect of a force of 60 kilograms per square millimeter. Or it is equivalent to 600 RN / mm². The yield point is 480 N / mm², which is equivalent to a force of 48 kilograms per square millimeter.

For the installation of various structures, the assembly of finished products, all kinds of fasteners are used, one of which is a bolt. Bolts, being a kind of metric fasteners, have different strength classes. This parameter indicates how much resistance the part has. refers to high-strength bolts, since its strength class corresponds to 5.8-8.8, depending on the material of manufacture.

It is the strength class, as well as the design features of these bolts, that allow them to be used to connect critical structures. Such structures are designed for shock, static, dynamic and other loads (for example, high pressure) that the finished product will experience during operation.

A distinctive feature of the Drive-Komplekt company, which supplies and sells bolts in an exhaustive range of standard sizes, is the constant availability of the required stock of the highest quality products in the warehouse.

It has not only a high strength class, but also design features. This is a metric fastener that is a threaded rod with a hex head. This type of bolt differs in that the thread is applied to the entire length of the rod (full thread).

Method of using hex bolts

The advantage of the head, which is possessed by DIN 933 Bolt with a hex head (with full thread) GOST 7798, is the increased quality of the connection. To fix the product, special box, socket or open-end wrenches are used to tighten the bolt as securely as possible.

In the process of using the bolts, they are installed in the fixing holes corresponding to the diameter, a nut is screwed on from the reverse side. Using a wrench or a wrench, the connection is fixed. To strengthen the connections and prevent spontaneous loosening of the nuts, flat washers or grovers can be used additionally.

Bolt din 933 photo

The increased strength and reliability of DIN 933 The bolt with a hexagonal head (with full thread) GOST 7798 acquires due to the material of manufacture and additional processing. The raw material for the production of bolts is alloyed or stainless steel of various grades. During the manufacturing process, the finished product is subjected to heat treatment, which makes it possible to apply great efforts to tighten them while maintaining the quality of the thread.

Of particular importance is the cost of bolts manufactured in accordance with 7805 ISO 40147. In the warehouses of the Travel-Komplekt company, with a guarantee of constant quality and a wide range of products, din 933 bolts are offered at the lowest prices.

The main industries where the use of bolts 7805 ISO 40147 cannot be dispensed with are mechanical engineering (primarily heavy), the installation of building structures that are subjected to heavy loads (including bridges). These fasteners are used in the installation of railway structures, in the manufacture of equipment and instrumentation, in the installation of industrial buildings.

But this does not limit the scope of application of full-threaded hex bolts. They are the most popular type of metric fasteners, reliably fastening parts made of almost any material (wood, metal, cement-concrete materials, plastic, etc.). Therefore, they are used in construction, furniture production and other industries.
