Not an extractor — the key for one pattern of locking wheel nut
TMAX S3054 wheel lock key, 40/23Pt
One wheel lock key, pattern S3054, for BMW locking wheel nuts — matched by pattern, not by vehicle.
What this actually is
A single socket key, 32 × 19 × 19 mm (1.26 × 0.75 × 0.75 in), with a 40 or 23-point internal pattern designated S3054, for removing BMW locking wheel nuts. Sold individually out of TMAX’s own 21-piece set. Not intended for use with an impact wrench. $8.89.
It is not a screw extractor, and it should not be bought as one
Everything else on this shelf removes a fastener that has failed — a head rounded off, a stud snapped, a Torx star stripped. This removes a fastener that is working exactly as designed.
A locking wheel nut has a fine splined or multi-point collar instead of a hex, and it is undone with a key cut to match. The key that came with the car lives in the boot tool kit, and when it is lost the wheel cannot come off.
So this is a replacement key, not an extraction tool. It is on this shelf because the shelf is where a reader looks when a fastener will not turn, and nothing else on this site covers it. Treating it as an extractor would be wrong in both directions: it will not touch a damaged nut, and an extractor will not fit this one.
If the locking nut itself is damaged — the splines rounded, the collar chewed by someone’s impact gun — this key will not grip it either. That is the job the rest of this shelf exists for, and the socket-type sets here are the nearest thing: VEVOR’s thirteen extractors from 1/4 to 3/4 inch go over a damaged head.
The pattern is matched by eye, not by vehicle
“To determine which key you need, visually match the key pattern to the locking lug nuts on your vehicle. Key compatibility is not based on the make, model or year of the vehicle.”
That is the sentence to read before ordering, and it is unusually honest.
Locking wheel nut patterns are made by a handful of suppliers and fitted across brands, model years and trim levels without following any of them. Two identical cars from the same year can carry different patterns, because the wheels were fitted at different times or replaced. S3054 is a pattern number, not a car.
So the method is: take the key off the nut if you still have one and compare, or photograph the nut’s face and count the points. “For BMW vehicles” in the title is a likelihood, not a specification, and TMAX says so in its own bullet.
And it must not be used with an impact wrench
“Not intended for use with impact wrench.”
A locking nut key engages on a shallow, fine pattern — forty points on a 19 mm (0.75 in) face means each point is less than 1.5 mm (0.06 in) of metal. An impact gun’s blows concentrate on those points, and what gives way is the pattern: either the key’s or, worse, the nut’s. A nut with a stripped pattern and no usable key is then a job for a specialist.
The other instruction in the listing is the one people skip: “When removing your lug nuts, it is best to evenly loosen each nut on the wheel as opposed to completely removing one at a time, this helps reduce pressure on the remaining nuts.”
That applies to every wheel, and it matters most here because the locking nut is the one with the least metal holding the tool.
Individual purchase, from a 21-piece set
“Individual pc now available from our 21pc set!”
Which is the reason this exists as a product. A 21-key set is bought by a tire shop that meets every pattern; a driver needs one key, the one that matches their car, and $8.89 for the right single key is the sensible purchase.
The corollary is that you have to know which one. There is no table of patterns in the listing and no cross-reference to vehicles — by design, since the bullet says compatibility is not based on the vehicle.
Thirty-two by nineteen by nineteen millimeters
A single socket, which is what the dimensions say: 19 mm (0.75 in) across the drive, 32 mm (1.26 in) long. That is a standard 19 mm (0.75 in) wheel nut socket length, so it reaches into a normal alloy wheel recess.
No drive size is published — a 19 mm (0.75 in) square section implies a 1/2-inch drive, which is what a wheel brace uses, but the listing does not state it. No torque rating is published either, which on a wheel nut tightened to 120 Nm or more is the figure that decides whether the key survives.
What is not published
No drive size. No torque rating. No material — no steel, no hardness, no finish, where every other listing on this shelf says something about its metal. No pattern diagram, so the visual match TMAX asks for has to be made against the photograph. No point count certainty — the title says “40/23Pt”, which is two numbers for one key. No warranty.
At $8.89 it is the right purchase for one lost key and one matched pattern, and it is not a tool for a damaged fastener.
