Double open end wrench sets

This category contains open end wrench sets from Seneca and XPTools. An open end wrench has an open jaw of a different size at each end, so a single set covers a large number of nut and bolt sizes.

The sets come in 8, 9 and 11 piece versions and are made of chrome vanadium steel. The largest sets range from 6x7 to 30x32 mm. There is also a professional set with extra thin wrenches, useful for slim nuts and tight spots where a standard wrench will not fit. An open end wrench set is a basic tool for the workshop, the garage, agriculture and home DIY. Combinations of open end and ring spanners can be found in the related categories.
