Production of HV screw grade 8/10 according to DIN 6914, direct purchase from Poladan

What specifications does the DIN 6914 standard determine?

Nominal thread diameter
Thread pitch
Screw length
Thread length
Screw head height
Screw head size for wrench
Screw head corner radius
Stem and threaded section dimensions

What is the difference between HV screws and normal screws?

What does grade 10.9 mean in DIN 6914 screws?

Common dimensions and sizes of HV screws

How is the production process of HV screw done?

Selection of raw materials

Screw head shaping

Create a thread

Heat treatment

Dimensional and appearance control

Control and packaging

Why is quality control critical in HV screw production?

A distinction must also be made between "dimensional compliance with DIN 6914" and "full compliance of an HV connection assembly with the requirements of the new EN 14399 standards". DIN 6914 has been transferred to EN 14399-4 according to standard sources; Therefore, in new projects, technical specifications and tender documents should be the final basis of selection.

Applications of HV screws in steel structures

HV screws are usually used in projects where reliable connection of steel members is of particular importance. Including:

Metal framework of buildings
Industrial silos
Heavy steel structures
Bridges and infrastructure structures
Beam and column connections
Truss member connections
Industrial equipment and structures
Construction projects requiring high strength connection

In these applications, simply buying the cheapest screw is not the right choice. Quality, traceability, resistance class and compliance with the technical specifications of the project are more important.

Choosing the right HV screw for the project

To make the correct choice, it must first be determined according to which standard the connection is designed. Then the diameter, length, resistance class, cover type and complementary components such as nuts and washers are determined.

For example, if the project plan specifies the use of an HV system, the appropriate bolt, nut, and washer assembly must be selected. Technical sources also emphasize that the components of this system are defined in the form of a standard set.

On the other hand, the length of the screw should also be selected based on the thickness of the connecting parts, washers, nut and the amount of thread required. Choosing the wrong length can make assembly difficult or change the connection conditions intended by the designer.

HV screw price depends on what factors?

The price of HV screws is not a fixed number and depends on various factors. The most important factors are:

Screw diameter and length
Strength class
Order weight
Steel type
Production method
Heat treatment
Covering type
Quality control and documentation
Order volume
Raw material price fluctuations

For this reason, it is better to announce the full specifications such as size, length, number, standard, resistance class and type of coating to get the exact price.

If you intend to buy in bulk, sending technical specifications to Poladan Sazeh can make the inquiry process faster and more accurate.

production of 10/8 grade HV screws; What is the advantage of buying directly?

Frequently asked questions about DIN 6914 HV screws

Is DIN 6914 the same as HV screw standard?

DIN 6914 is a standard for large spanner width hex bolts in high-strength structural fasteners. This standard has been replaced by EN 14399-4.

What is the standard DIN 6914 screw grade?

In technical sources, the DIN 6914 screw resistance class is 10.9. Therefore, the expression "10/8" should not be considered as a DIN 6914 standard class without checking the project specifications.

In what sizes are HV DIN 6914 screws produced?

Common sizes include M12, M16, M20, M22, M24, M27, M30 and M36; Of course, the exact range that can be provided should be checked based on the standard and specifications of the order.

Are HV screws only used for the building frame?

No. These screws are used in all kinds of steel structures, sheds, bridges, industrial structures and connections that require high strength.

Should HV bolts, nuts and washers be selected together?

Yes. In HV systems, compatibility of connecting components is very important. Related standards for screws, nuts and washers have defined additional specifications.

What information is required to inquire about the price of HV screws?

It is better to state the diameter, length, number, resistance class, standard, type of coating and requirements related to quality documents. With this information, you can receive a more detailed inquiry.

How to inquire from Poladan Sazeh?

For inquiries, you can call 09393223607 or send your order details via Poladan Sazeh website.

summary

Production of HV screw grade 10.8 is a sought-after term for high-strength structural screws, but in terms of the standard, it should be noted that DIN 6914 specifies class 10.9 for HV screws. Also, this standard has been replaced by EN 14399-4 in the structure of new standards.

Therefore, for purchase or production, it is better to check the actual technical specifications of the project instead of relying on the market name. Diameter, length, resistance class, coating, type of connection and compatibility of screws with nuts and washers all play a role in the final choice.

If you need HV screws, DIN 6914 screws or high-strength structural connections for your project, prepare the technical specifications and required quantity and contact Poladan Saseh for inquiries.
