Bolts

Buy bolts wholesale in Ukraine

Bolts are one of the most common types of threaded fasteners, used in construction, mechanical engineering, equipment manufacturing and the assembly of steel structures. These fasteners consist of a threaded shank and a head of a specific shape, ensuring a secure structural connection.

You can buy bolts in Ukraine on the Dinmark website. Our range includes DIN, ISO, GOST and DSTU bolts for professional and industrial use. Our online shop offers products in various sizes, strength grades and coating types.

If you need to buy in bulk or place an order for manufacturing, construction or repair, please contact Dinmark’s managers; they will help you find the best solution. The company delivers throughout Ukraine, including to Kyiv, Lviv, Lutsk, Ternopil and other cities.

Purpose of bolts

Used to create strong and durable connections across various industries. Depending on the application, they may differ in head shape, thread type, strength class and material.

Purpose of bolts

They are used to create strong and durable joints across various industries. Depending on the application, they may differ in head shape, thread type, strength class and material.

Main types:

• road bolts used for the installation of road and fencing structures;
• engineering used in the manufacture of machinery, mechanisms and equipment;
• furniture designed for assembling furniture and wooden structures;
• plough used in agricultural machinery;
• structural suitable for critical metal joints.

A correctly selected fastening bolt ensures high strength and resistance to loads.

Areas of application

Used in various sectors of industry and construction:

• construction;
• mechanical engineering;
• equipment manufacturing;
• food industry;
• agriculture;
• steel structure assembly;
• solar panel installation;
• automotive industry.

Thanks to a wide range of standards and sizes, it is easy to find the right one for any structure.

Basic classification of bolts

By head type and size

The Dinmark catalogue features the following bolts:

• hexagon head bolts – versatile products suitable for most assembly work;
• countersunk head bolts – used where fasteners need to be concealed;
• with a half-round head suitable for soft materials;
• with a flange ensure reliable clamping of parts;
• eye bolts have a ring-shaped head;
• toggle bolts used in adjustment mechanisms.

Bolts come in various sizes ranging from compact models for furniture production to large structural hardware.

By shank shape

Depending on the design, the shank may be:

• standard diameter;
• thickened;
• reduced diameter.

The shank shape is selected according to the loads and operating conditions.

By thread pitch and type

Bolts are manufactured with:

• standard metric thread;
• fine thread;
• special thread types for specific manufacturing sectors.

A fine thread pitch provides better resistance to vibrations and dynamic loads.

Strength grades

They are manufactured from steel of various strength grades, ranging from 3.6 to 12.9. The most common grades are 5.8, 8.8, 10.9 and 12.9.

High-strength products are used in critical structures where maximum strength and safe operation are essential. Bolts of grade 8.8 and above are capable of withstanding significant mechanical loads.

Bolt coatings

To protect against corrosion and extend service life, the manufacturer uses special coatings: zinc plating; hot-dip galvanising; yellow zinc; Dacromet; nylon coating.

Such coatings help protect the steel from the effects of moisture, temperature fluctuations and aggressive environments.

Bolt materials

The following materials are used in the manufacture of fasteners:

• carbon steel;
• alloy steel;
• A2 and A4 stainless steel;
• high-strength alloys.

Stainless steel bolts remain the most popular, as they are corrosion-resistant and suitable for use in harsh conditions.

Many products are made from steel that has undergone additional heat treatment, which increases their strength and wear resistance.

Manufacturing standards

Bolts are manufactured in accordance with international and Ukrainian standards:

DIN; ISO; GOST; EN; PN.

DIN standards are widely used in construction, mechanical engineering and industrial manufacturing.

Mechanical properties of bolts

Mechanical properties directly influence the product’s scope of application.

• Strength classes 4.8 and 5.8 are suitable for standard loads;
• Class 8.8 fasteners can withstand increased loads;
• Classes 10.9 and 12.9 are used in critical structures;
• Stainless steel bolts are suitable for use in damp environments.

A correctly selected bolt ensures the durability and safe operation of the structure.
