Ingco Offset Ring Spanner 11x13mm HOSPA11131

Our review

This is a double-ended offset ring spanner from Ingco, sized 11mm at one end and 13mm at the other, with a fine polished finish. The offset shape is the point of it: the ring sits at an angle to the handle, which lets you turn a nut or bolt head that sits close to a surface or recessed where a flat spanner would foul. It suits someone doing regular mechanical or maintenance work who wants one tool covering two common metric sizes rather than two separate spanners. Before buying, confirm 11mm and 13mm are actually the fastener sizes you meet most, since a spanner is only useful if it fits. Compare against a standard flat ring spanner if you rarely work in tight spaces, and against a full set if you need a wider range of sizes. Check the ring is a proper fit on your nuts to avoid rounding corners.
