Dear sirs and ladies!

Tchaikovsky Factory of Fasteners is the producer and supplier of fastening products. We keep to Sate Standard (GOST) when producing bolts, brads and screw nuts; the GOST is used on the territory of Russian Federation.  

Foreign countries use their own State Standard (DIN) at production. These both standards are normative-technical documents for the production of products; adherence to these documents will guarantee the quality of the product.

Construction and sizes of Russian and Foreign standards are similar. A comparison table of standards is shown below to point out the standards according to which our factory works.

You’ll get fasteners according to the standard DIN if you order the fasteners according to Russian standards.
