The strength class of a bolt according to GOST 13152-67 is the maximum applied force at which the bolt begins to fracture. GOST 13152-67 bolts are manufactured in strength classes 4.6 and 8.8. From strength class 8.8, the bolt is considered high-strength. High-strength GOST 13152-67 should be purchased only from trusted suppliers. It is made of alloy steel and such bolts are used for critical projects where, in addition to high loads and static loads, GOST 13152-67 bolts are subjected to constant vibration.
Fastening group of GOST 13152-67
Depending on the material of manufacture, bolts of GOST 13152-67 are divided into groups:
- High-strength fasteners - fasteners made of high-strength structural alloy steel
- Stainless fasteners - fasteners made of stainless steel.
Materials for the manufacture of GOST 13152-67 bolts
GOST 13152-67 bolts are manufactured in the following materials:
- Steel of strength classes 4.6 and 8.8, which can be additionally coated with zinc. Zinc (Plated) protects against corrosion if the fasteners are to be used in aggressive environments
- Stainless steel grades A2 and A4. Allows the use of DIN 186 at significant temperature changes and in aggressive and humid environments.
Application range of GOST 13152-67 bolts
GOST 13152-67 is a fastener used in the production of various types of machine tools, it is used for installation in prepared holes and reliable fixation of parts. Bolts of this type can also be used in other areas of mechanical engineering, automotive, instrumentation, and more. They are used to connect parts in production machines, as well as in industrial, engineering and construction applications.
