Galling refers to the wear and tear occurring between two metal surfaces due to friction when they happen to be in sliding contact with each other. Thread galling is prevalent amongst threaded fasteners which are fabricated from stainless steel, steel, aluminium or brass. Therefore, correct steps must be taken from the start in order to lower the risk and occurrence of thread galling. What are the effects of thread galling? What must precautionary measures be employed in order to protect threaded parts such as fasteners, nuts, and screws from galling? Read the following post to get answers to these questions.
Galling causes a bump, gall or tear in threaded fasteners, screws, and bolts. When the surfaces of threaded parts get eroded, they leave behind a small cavity or hole in them. This causes microscopic particles to accumulate inside the cavity of the threaded parts. This affects the design and efficiency of threaded parts such as fasteners, nuts, and screws. Below are some negative implications of galling, which seriously affect the design and construction of the mechanical parts.
Various effective measures are taken for protection against thread galling. Here are some measures:
All these galling prevention strategies help to increase the longevity and efficiency of a threaded fastener, nut or screw. If planned beforehand, it can also help avoid costly repairs and servicing.
