Opening and fixing a shower valve.

Hi all,

I am trying to open up a shower valve. Since the hot-col mixing knob is stuck and I would like to soak it in vinegar.
Unfortunately, as I tried to open up the shower valve. After trying many screw's up to 1/16' allen key screw I have failed miserably and need some help.

Effectively, if someone could guide me on the screw type that is shown in the picture (attached). I will go get the corresponding sized screw set from Home Depot.

Thanks

Welcome to the forums.

There is no standard unless you know the make and model of that valve.
I carry sets of hex keys in both standard (SAE) and metric sizes.
Many times a metric key will work on a problem set screw.

Hey key sets are also available at Walmart, $1.20 each for metric and imperial.

On your adjustor knob, is that a switch on the front, the flattened cone shape? I'm wondering if that is hiding retaining hardware underneath.

I blew the picture up as far as I could and it almost looks like a Torx fitting. Can you get a better/closer/clearer shot?

I also blew it up.
It does not look like anything I have seen.
Outer ring looks to have a slot at the 11 and 5 o'clock locations.
Then further in is what looks like a hex key but at the 1 o'clock position there is a triangular indent,

A make and model may be the only way to find out what is required.
I would try unscrewing the handle, they often come off that way.
But the key will still have to come off, I think.

I would spray some liquid wrench in there as it is probably gunked in pretty good.

Every faucet I have run into use Allen. If you have ball end Allen wrenches don't turn too hard using the ball end. If it doesn't break free with moderate force use the short, non-ball end of the wrench. It better engages the head of the set screw with less chance of stripping out.

The shower valve is a hansgrohe.
I tried a host of allen-hex keys, but I don't have a ball-ended or a torx (need to go buy one, when I go out perhaps once this week).

@CycleZen : It is not easy to pull out the cone shaped , I tried with my channel-lock pliers and was not successful.

I tried WD40 but the shower valve was all locked up. I don't have "liquid wrench" .

Add a few more pics, which makes it a little clearer.

I was perusing around the Hansgrohe site. It appears their handles are held on with metric setscrews.
Yours may use a 4mm allen key.

When you go out.... get a metric hex key set.

Just my opinion but I feel WD-40 is pretty much useless.

So I would buy some liquid wrench.
Spray some in and let it sit fotr a couple hours, sometimes it take 24 hours..
If it just runs out then put in a loose piece of paper tower and soak it.

Once you get the correct hex if it will not turn give the wrench a couple taps with a hammer,

Thanks folks, I will probably have to wait for that trip for a week, given the shelter-in-place order and County orders. I have closed out that shower supply for the time being and will update the thread once I get some "hardware".
