Combined wrenches

Open-ended

— combined wrenches, on one side of which there is a working profile of an open-end type, on the other — a cap; profiles are usually the same size. Such versatility allows you to choose the working part depending on the specific task: for example, a spanner wrench is well suited for unscrewing a stuck bolt, and an open-end wrench is required for a pipeline fixing nut. For more information about each type of work profile, see the corresponding paragraphs.
