Under the sink
The nut you cannot reach is the whole job.
A faucet is held on by nuts that sit up behind the basin, in the dark, in a gap the width of your wrist, with the supply lines running straight past them. A normal wrench cannot get on them and a socket cannot get over the line. This is a 25 cm bar with a slot down its whole length: it drops over the supply riser, slides up, and puts a socket on the nut above.
Read this first: it is a plastic wrench, and that sets the limits.
The body is ABS with an aluminum insert in the head. That is enough for nuts that were put on by hand and for the everyday plastic and brass nuts under a sink. It is not the tool for a 20-year-old nut welded on by corrosion — that one wants penetrating oil, a steel basin wrench, or a cut-off tool. Lean on this one hard enough and the plastic is what gives.
Two things to check before you order: what shape your nuts are (there is a chart further down — four common types fit, two do not) and what size they are. The openings are metric: 21, 24 and 28 mm in the head, plus cups for 34–35 and 40 mm.

The slot
Why it is cut open down the side
Look at the second view: the body is hollow with a channel running its full length. That is not styling. The mounting nut you want is directly above the supply line that is screwed into the same shank, so a closed socket can never be dropped onto it. This one goes on sideways — the line passes through the slot, the socket ends up on the nut, and you turn the bar.
Both ends work. The aluminum insert in the head takes 21, 24 and 28 mm; the tail end is a smaller square that reaches into the tighter spots, and the two red cups push on for the big 34–35 and 40 mm nuts.
What it turns
Four nuts you meet on nearly every job
Faucet mounting nuts behind the basin. Supply-line coupling nuts where the braided hose meets the shank or the valve. Shut-off valve packing nuts on the wall. Sink strainer and basket nuts under a kitchen sink.
Same handful of sizes, same awkward angle every time. That is the case for one purpose-shaped bar instead of a basin wrench, two open-ends and a pair of pliers you cannot swing anyway.
Check yours first
Four nut shapes fit, two do not
This is the maker’s own compatibility chart and it is the most useful picture on the page. The four that fit are the ones with flats or lugs to grip: plain brass hex and ring nuts, the ribbed plastic flange nut, the coupling nuts on braided supply lines, and the brass flange nut with tabs.
The two crossed out are a deep black plastic nut and a smooth round chrome one. Take a photo of yours with a phone before you buy — getting under there twice is the part nobody enjoys.
The extractor
For the screw head you already rounded off
A 75 mm T-handled extractor rides in the tail of the wrench. Its coarse reverse thread bites into a chewed-up screw or a broken stud and backs it out as you turn counter-clockwise.
It is a small extractor for small fasteners — the ones in a faucet handle, an escutcheon or a bracket. A seized machine screw in steel is a job for a drill and a proper extractor set, and forcing this one just snaps it.
8-in-1 or 14-in-1
The difference is two adapters
Both kits are the same wrench, the same aluminum head, the same level, the same screw extractor and screws, and the same two push-on cups for 34–35 and 40 mm nuts.
The 14-in-1 adds two more push-on adapters, marked by the maker at 16 / 18 / 28 mm and 20 / 22 / 44 mm. If the nuts you already know about are covered by the sizes in the 8-in-1, the smaller kit is the whole tool; the 14-in-1 is for not knowing yet.
Straight answers
What it is not
There is no ratchet in it. Listings for this tool elsewhere describe a ratchet mechanism and a double-headed handle. Look at the photos: it is a moulded bar with sockets at both ends. You turn it, let go, and take a fresh grip, the same as any T-bar.
It is not insulated and carries no rating. Some sellers list “insulated” among the features. There is no insulation rating here and no certification, so treat it as an ordinary hand tool and keep it away from anything live.
It is not a torque tool. Plastic nuts under a sink want hand-tight plus a nudge. This bar makes it easy to go well past that and crack a plastic nut or a flange.
Never put a pipe over it for more leverage. On a steel wrench that is a bad habit; on an ABS body it is how the tool ends up in two pieces with your knuckles against the cabinet.
The maker’s own numbers disagree. Its drawings put the length at 245, 250 and 253 mm on different images, and label the smaller cup 34 mm in one place and 35 mm in another. We quote it as about 25 cm and 34–35 mm rather than pick the flattering number. Measure your nut across the flats.
Before you loosen anything
Close both shut-off valves, open the faucet, and let the pressure go. Keep a bucket and a towel under the joint — a supply line holds water after the valve is shut.
If a shut-off valve will not turn or will not seal, stop. That is now a valve job, and the main has to come off first. An old multi-turn valve that has not moved in a decade often will not reseat.
Eye protection, and a light you do not have to hold. You will be looking straight up into whatever falls off. Braided lines that are rusted at the ferrule get replaced, not reused.

Questions people ask
Before you order
Will it fit my faucet?
Check the shape against the chart above, then the size. Four common nut shapes fit and two do not. The openings are 21, 24, 28, 34–35 and 40 mm, with two more adapters on the 14-in-1 kit.
My nuts are in inches. What do the metric sizes work out to?
21 mm is about 13/16 in, 24 mm about 15/16 in, 28 mm about 1-3/32 in, 34–35 mm about 1-11/32 in and 40 mm about 1-9/16 in. Measure across the flats of your nut and compare — a socket that is a hair too big rounds a plastic nut off fast.
8-in-1 or 14-in-1?
Same wrench. The 14-in-1 comes with two extra push-on adapters covering 16 / 18 / 28 mm and 20 / 22 / 44 mm. If the nuts you are going after are inside the 8-in-1 sizes, the smaller kit does the job.
Does it have a ratchet?
No, whatever other listings say. It is a solid moulded bar with sockets at each end. In a tight cabinet you turn it as far as the space lets you, lift it off and start again.
Will it shift a nut that is rusted on?
Often not. Plastic gives before a corroded steel or brass nut does. Spray a penetrating oil, leave it, try again — and if it still will not move, that is a steel basin wrench or a cutting job, not this one.
Does the slot really pass over the supply line?
That is the whole design. The channel runs the length of the body so the tool can come in from the side of a riser rather than down over it, which is what puts a socket on a nut you cannot see.
Is it strong enough for a kitchen strainer basket nut?
For a basket nut that was hand-tightened and has not seized, yes — that is one of the jobs it is shaped for. For one that has been locked in place by years of hard water, use a steel basket wrench.
What is the level for?
Setting a fixture straight while you tighten it — a faucet body, a shower arm, a valve escutcheon. It is a rough bubble vial, useful for eyeballing, not a substitute for a real level on cabinetry.
Can I put it on a drill or an impact?
No. There is nothing to drive it with, and powered torque on a plastic bar and a plastic nut ends the same way every time.
