Bolts according to DIN 933 have structural analogues - these are GOST 7798, GOST 7805, EN ISO 4017 (minor 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 a full thread according to DIN 933 that is most often used in mechanical engineering, when carrying out installation work, and connecting various elements. In its unchanged form, it is found in all countries of the world and has not been inferior to its 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 transfer a lot of torque, and not break the edges. Access both from above and from the side is possible;
- attractive price-quality ratio;
- the widest range of sizes: it is currently possible to supply bolts from M2 to M72 with a length of 3mm to 600mm. You can purchase bolts from the availability of diameters from M 3 to 36 in the TsKI Group of Companies;
- 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 available commercially both uncoated and with various options (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 above are called high-strength.
Bolts can be mounted both in the body of the part and connect several elements together. 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 maximum efficiency of the connection.

The main distinguishing feature of bolts manufactured according to the requirements of DIN 931 and DIN 933 is a different thread rolling zone and different minimum and maximum length ranges.
Bolts manufactured according to DIN 931 have partial threads up to 153 mm long, 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 run-off zone, which must be taken into account when calculating the length of the bolt in the connection. The maximum bolt length according to this standard is limited to 340 mm, and the minimum is 5 mm.
An analysis of the structural differences between 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 connection is not less than 18 mm, as well as in cases of through connection of parts of great thickness or using them as a screed for plates separated by a considerable distance. The main area of application is construction. Bolts according to DIN 933, due to the minimum prescribed 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 with separate fixation of each with nuts. The main 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 hexagonal head. The bolt shank is fully threaded. These bolts are made from steels of various strength classes and can have different 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, assemblies, 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 highly durable 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, steel grades A2, A5 are used. These are stainless steels, which give the bolt special strength and excellent corrosion resistance.
If this bolt is intended for fastening units and parts that will work in aggressive environments, then additional processing is carried out. The fastener is covered with protective materials by applying a thin layer of zinc to the surface by galvanic or hot method. Nickel plating of the bolt in galvanic baths is possible. Thermal diffusion galvanization is used, and chromating by galvanic method is also carried out on request.
In special cases, hardware companies of the country fulfill orders for the manufacture of DIN 933 bolts from such durable 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 appropriate class 6 nuts.
Bolts DIN 933 6.8 strength class have a tensile strength, which is equal to the impact of a force of 60 kilograms per square millimeter. Or it is equivalent to 600 PH/mm². The yield strength 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, various fasteners are used, one of which is a bolt. bolts, being a kind of metric fasteners, have a different strength class. This parameter indicates how much resistance the part provides. refers to high-strength bolts, as 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 make it possible to use them for connecting critical structures. Such designs 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 Trayv-Komplekt company, which supplies and sells bolts in an exhaustive range of standard sizes, is the constant availability of the necessary stock of the highest quality products in the warehouse.
It has not only a high class of strength, but also design features. This is a metric fastener, which is a threaded rod with a hexagonal head. This type of bolt differs in that the thread is applied to the entire length of the rod (full thread).
How to use hex bolts
The advantage of the head, which DIN 933 Hexagon head bolt (with full thread) GOST 7798 has, is the increased quality of the connection. To fix the product, special ring, 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 mounting holes of the appropriate diameter, a nut is screwed on the reverse side. Using a wrench or wrench, the connection is fixed. To strengthen the connections and prevent spontaneous loosening of nuts, flat washers or Grover can be additionally used.

Increased strength and reliability DIN 933 GOST 7798 acquires a bolt with a hexagonal head (with a full thread) 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 produced in accordance with 7805 ISO 40147. At the Trive-Komplekt warehouses, with a guarantee of consistent quality and a large product range, din 933 bolts are offered at the lowest prices.
Applications for high security bolts
The main industries where the use of bolts 7805 ISO 40147 is indispensable 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, the manufacture of equipment and instrumentation, and the installation of industrial buildings.
However, the scope of application of hex bolts with a full thread is not limited to this. They are the most popular type of metric fasteners, reliably fastening parts from almost any material (wood, metal, cement-concrete materials, plastic, etc.). Therefore, they are used in construction, furniture production and other industries.

The minimum value prevails.
Only for bolts without protective coatings. 6 g allows the use of normal layer thicknesses in accordance with DIN 267, part 9, where the zero line must not be exceeded. Depending on the required layer thickness, the limit deviation should be the same as for g-level. A limit deviation exceeding this value can cause the bolt-nut connection to loosen.
4 Symbol
Symbol for a hexagon head bolt with thread size d = M12, nominal length l = 80 mm, strength class (material) 8.8:
Sechskantschraube DIN 933 - M12 X 80 - 8.8
If it is necessary to indicate the accuracy class A for dimensions not exceeding M24, with a length over 150 mm, in particular, for /> 10d or for dimensions over M24, then the accuracy class is indicated in the symbol, for example:
Sechskantschraube DIN 933 - M30 X 100 - 8.8 - A
DIN 262 is used as additional ordering information for the designation of shapes and designs.
For the conditional designation of versions equipped with integral parts (combined bolts), DIN 6900 is used.
For the designation of rolled thread versions, DIN 7500 part 1 is used.
For bolts conforming to this standard, the tabular representation of the characteristics of DIN 4000-2-1 is used.
Appendix A Additional dimensions for spare parts
The previously used sizes M1.7, M2.3 and M2.6 are not included in the international thread size catalog and should no longer be used. However, they can be ordered in accordance with DN 933 issued in December 1970, taking into account the available documentation and the need for the supply of spare parts. Bolt sizes are shown in the table below. Thread specifications are in accordance with DN 13 part 1 and part 15.
