Most of the taps in my new house are fitted with so-called "anti-vandal" screws in the tap heads, as shown in the image. These screw into the tap head to tighten them onto the stem.
I can't remove most of them because they are stuck. I suspect they've been overtightened and haven't been removed for years. I'm looking for suggestions as to how I can remove them so I can replace the tap washers. And yes, I know which way they need to be turned to tighten or loosen them ;-)
I've already tried:
- Using an anti-vandal tap head spanner (shown below), but the prongs bend/break, as the screws are quite stuck.
- Using a hair-dryer to heat up the ring before using the spanner.
- Adjusting the rings to tighten, then to loosen. I simply get no movement at all.
- Applying WD-40 to the rings. This hasn't worked either, perhaps because of their orientation; I can't immerse them.
I also have a pair of needle-nose pliers, but they're just a bit too big for the notches in the rings to get a good grip.
Any other suggestions?
- UNECS's suggestion (below) was certainly a good one, but unfortunately it didn't work out.
- I now have my hands on a small pair of 90° circlip pliers which I'll try later. Hopefully I don't break them (or anything else) in the process!
