GOST 5929-70 Hexagonal low nut is a fastener with a thread that prevents self-detachment of connected fasteners of increased height or standard height. The main functional feature of the product is its ability to reduce the installation space. Such fasteners are used in cases where it is necessary to ensure the safety of the connection under high loads.
Strength class GOST 5929-70
Nuts of GOST 5929-70 are made of steel of strength classes 4 and 5. The strength class of a nut Din 439 is the maximum applied force at which the nut begins to fracture.
Fastening group GOST 5929-70
Depending on the material of manufacture, nuts of GOST 5929-70 are divided into groups:
- Stainless steel fasteners
- Brass fasteners
Materials for the manufacture of nuts GOST 5929-70
Nuts of GOST 5929-70 are made of various materials:
- Steel, which can be additionally coated with zinc, yellow zinc, and zinc plate
- Brass. Brass nuts are used when the system is subjected to frequent dynamic, vibration, and cyclic loads.
- Stainless steel grades A2 and A4. Allows the use of bolts at significant temperature changes and in aggressive and humid environments.
Scope of application of GOST 5929-70 nuts
GOST 5929-70 is used in shipbuilding, mechanical engineering, instrumentation, and furniture production together with nuts and bolts of the corresponding threaded connection.
The nut of GOST 5929-70 prevents the threaded connection from loosening; in this case, the nut is used only in conjunction with a standard nut, the counter-locking in this case is applied using two tools, and the nuts are tightened towards each other.
Adapted for use in tight spaces, but due to its height, the nut cannot be used with standard tightening torques.
