Socket wrenches

End

— keys with a working part in the form of a cylindrical cap, put on the fastener from the end (hence the name). Designed primarily for use with bolt heads, as well as nuts from which the bolt does not protrude or protrudes very close; not suitable for working with pipelines, hoses and other parts in which there is no way to get to the fasteners from the end. On the other hand, many of these wrenches are able to reach even a deeply recessed bolt or nut, and the working surface covers the fastener from all sides and is in close contact with it, allowing you to develop high efforts during work without much risk of breaking the edges.
