The GOST 22033-76 stud is a threaded connecting part with tapped ends used to connect machine and mechanism parts. GOST 22033-76 belongs to the group of studs with a thread diameter tolerance of 1d, which means that the thread diameter of a stud may differ from the nominal value by +/- 1 thread diameter. For example, if the nominal thread diameter of GOST 22033-76 is M10, then the thread diameter tolerance 1d will be equal to M10 +/- 0.1 mm. Thus, the actual thread diameter can be in the range from M9.9 to M10.1 mm.
Strength class of GOST 22033-76
The strength class of a GOST 22033-76 stud is the maximum applied force at which the stud begins to fracture. Studs of GOST 22033-76 are manufactured in strength classes from 5.6 to 8.8. From strength class 8.8, the stud is considered high-strength.
Fastening group of GOST 22033-76
Depending on the material of manufacture, studs of GOST 22033-76 are divided into groups:
- Stainless fasteners
- High-strength fasteners
Materials for the manufacture of GOST 22033-76 studs
Studs of GOST 22033-76 are made of the following materials:
- Steel with a strength class of 5.6 to 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. The steel grade allows the fasteners to be used at significant temperature drops and in aggressive and humid environments.
Application range of GOST 22033-76 studs
Studs of GOST 22033-76 are used in such industries as automotive, instrumentation, and large studs are also actively used in construction, in the installation of metal structures and wooden elements.
