Set of socket head 3/8 Stanley 2-85-583 differs from its analogues on the line offers a brand that the manufacturer used here as a basis for proposals focused on twelve faces, while most other solutions are focused on the 6 faces. Almost a classic case here in the set has been added to the handle, which in his work is based on a ratchet principle. If necessary, you can always resort to using embedded in the extension kit. Separately not hurt to mention the presence of the adapter, as well as cardan joint spectrum.
