Overview
GOST 2528-73 is a castellated nut used on various types of axles and shafts subject to vibration and dynamic loads. Holes are drilled in these axles into which, after tightening the nut, cotter pins are inserted, which in turn pass through vertical slots in the nut. This allows the nut to be securely fixed and prevents it from loosening during vibration.
Strength class of GOST 2528-73
The strength class of a nut in accordance with GOST 2528-73 is the maximum applied force at which the nut begins to fracture. DIN 935 nuts are manufactured in strength classes 6 to 10. From strength class 8, the nut is considered high-strength.
