Steel lock nut is a fastener used in pipeline systems to ensure a secure connection between pipes and fittings. It serves to prevent spontaneous loosening of threaded connections under the influence of vibrations or other mechanical loads. Lock nuts can be made of various materials, but steel lock nuts are the most common due to their strength and durability.
Design and dimensions
Steel lock nuts have an internal thread that matches the external thread of the pipe or fitting to which they are connected. GOST 8968-75 defines the dimensions and characteristics of such products.
Application
Lock nuts are used in various fields: from water supply to gas supply and heating. Their installation requires care - the nut must be tightened until it stops to ensure a tight connection without damaging the thread. It is also important to consider the pipe material when choosing a lock nut: for steel pipes it is better to use steel lock nuts, and for plastic pipes - the corresponding plastic models.
