Finding The Set Screw:

The handle in your shower will not come directly. It is necessary to first release the set screw.
This set screw actually keeps the handle stick to the valve stem. Otherwise, the attachment won’t let you remove the handle.
It’s Hard To Find The Screw:
If you are having problems finding the screw, you are not the only one there. This is a problem that many individuals out there face on a regular basis.
The manufacturer conceals it with an ornamental cover and positions it on the handle in a way that makes it less likely that you will notice it on purpose.
If you can find the cap, then you can find the set screw.
The Lever Design Of Set Screw:

Nowadays, we see the set screw for a handle with a lever design.
The same style is available in most Delta faucets or showers that come with a single-handle design. The set screw here is located just beneath the lever.
You might have to stoop down in order to get it.
Just Turn Off The Faucet:
It is comparatively easy to find the set screw after turning the shower off. Just look at the handle cover.
It will then face the rear wall of the sink. You will just get the screw on the cover handle; could be on any side of it.
This results in an additional difficulty in that you will need to turn off the water before you can access the screw by twisting the handle.
If the valve is to function properly, this task will ultimately need to be performed. So, it is not a major issue.
Remove The Cap Now:

After you have located the cap, you might be perplexed by how tough it appears to be to remove it.
It is not necessary to do anything more than pull it out with a screwdriver that has a flat head; it will come off without any difficulty at all.
Be very careful, though, as it is rather tiny. In fact, if you’re not careful, it may go straight down the drain and drags you into a further problem.

Having The Right Allen Wrench Is Important:

When you remove the cap, you have easy access to the set screw. Now you know what to do next.
Simply, use the right size Allen Wrench to remove the set screw. Then you will have the handle in your hand.
As we have stated earlier, the standard size for a wrench is a 3/32 Imperial Allen Wrench or a 2 mm metric Allen Wrench.
Unless the manufacturer says otherwise, one of these wrenches will do the job. So, you better check the shower manual beforehand.
Once you have the confirmation, grab an Allen Wrench of the mentioned size and deal with the handle of your Delta Shower.
It May Be Difficult To Rotate The Set Screw:
You have verified that the wrench is the correct size and that there is sufficient space to work. But even after inserting the wrench, the screw will not turn.
Be patient, but don’t force it. Doing so risks the breaking of the wrench.
If you break it, it would require you to resort to drastic measures such as sawing off the handle or prying it open with a crowbar. A new faucet may even be necessary.
Use Lubricants Here:
So, you should not force it. Rather you can take resort to lubricants. place the tube of the lubricants in the aperture of the screw.
And then apply a few sprays of the lubricant to the screw.
At the very least, let it five minutes to settle down before giving the screw another shot. The problem isn’t solved yet?
It should be sufficient to give it a few more spritzes, then wait another five minutes before giving it another shot.
