Overview

The HARFINGTON wrench set covers three double-ended sizes, 3/8 by 7/16 inch, 1/2 by 9/16 inch, and 5/8 by 11/16 inch, each 165 millimeters long with a combined weight of 0.15 kilograms.

Covering three size pairs in one purchase means six total openings across the set, useful for matching odd-sized fasteners without buying single wrenches one at a time. The 165mm length and light 0.15 kilogram weight point to compact, standard open-end wrenches rather than long-handled or heavy-duty versions.

Who it's for

Fits anyone assembling a home or garage toolbox who wants a spread of common inch sizes in one order. Not the choice for jobs needing a single oversized wrench or high-torque breaking force, where a longer handle offers more leverage.
