Tronic Combination Spanner — Open and Closed Loop Ends

Our review

A combination spanner gives you two tools in one shaft: a closed loop at one end that grips a nut or bolt head all the way around, and an open-ended profile at the other that slides on from the side. Tronic angles both heads relative to the shaft, which is the usual way makers improve access in tight spots where a straight tool would foul the surrounding metal. That makes this a sensible pick for someone building a first toolkit or replacing a single missing size, since you are not buying two separate spanners to cover the same job. Before buying, confirm the size you actually need, because a spanner only works on the matching nut or bolt head, and check whether you want metric or imperial across your set. Compare it with a ring spanner, which grips more securely but only fits where you can approach straight on, and with an adjustable wrench, which covers many sizes but can round off a stubborn head. If you already own a socket set, a combination spanner still earns its place for the open end and for reaching where a socket and ratchet will not fit. Look at the finish and the feel of the jaws when it arrives, and keep it dry to limit rust. Available on Sokonia.
