Ingco Double Open End Spanner Set, 12 Pieces, 6–32mm, HKSPA2142

Our review

This is a twelve-piece set of double open end spanners from Ingco, covering metric pairs from 6x7mm through to 30x32mm. Each spanner has an opening at both ends, so one tool handles two adjacent sizes, which keeps the count down without leaving gaps in the common range. The sizes step through 6x7, 8x9, 10x11, 12x13, 14x15, 16x17, 18x19, 20x22, 21x23, 24x27, 25x28 and 30x32mm, and the finish is fine polished. It arrives packed in a canvas bag rather than a metal case or rack.
It suits someone building out a first proper tool kit, a mechanic who wants a spare set for the bench, or a household that keeps running into metric nuts on vehicles, gates and machinery. Because the range runs all the way to 30x32mm, it also covers larger fasteners that a basic set stops short of. The canvas bag keeps the pieces together but will not hold them as rigidly as a roll or case, so if tidy storage matters, plan for that.
Before buying, check the fasteners you actually work on. Double open end spanners are thinner than combination spanners and reach nuts a ring end cannot, but they grip on two flats only, so they are a poor choice for tight or corroded bolts where a ring or socket is safer. Confirm you need metric sizes, since this set is entirely metric. Compare against a combination set if you want ring ends, and against a single-ended set if you would rather buy only the sizes you use. Available on Sokonia.
