Problem Unscrewing Sink Strainer: Tips to Loosen & Replace (Photo Attached)

Question

I have such a problem that I am unable to unscrew the strainer from the sink. I wanted to replace them with new ones, but unfortunately the screw does not budge. You have a patent for it. Picture of the strainer in the attachment.

Non-destructive: Patiently and systematically spray WD40 every hour and try to unscrew the next day. Or destructively: mini grinder and gently score the sieve arms. Alternatively, tear out or cut out the plastic element from the other side, because you will probably have to replace it with the gaskets anyway.

We have:

You need to cut the screw underneath the sink / washbasin together with the siphon tube.
/ more modern ones can use an angle grinder

Of course, you have to buy a whole new siphon, not only a strainer, anyway after even non-destructive disassembly of the siphon
after a few years of use, you need to buy new / worn gaskets, ugly appearance, etc.

Maybe not entirely to the point, but a further destructive unscrewing suggestion. In order not to have a problem with such a screw, I recently bought something like this:

Start spinning the tube from the bottom.

There is a classic saying for mechanics, locksmiths, plumbers - "nothing by force, just a hammer", because doing "force" usually causes a screw to twist.
It is a good idea to gently tap this screw with a small hammer using, for example, a more massive screwdriver. After inserting the screwdriver into the incision, the screw can be unscrewed with gentle blows of the hammer. You can also unscrew the nuts with a sharper screwdriver or chisel.
In any case, it is worth tapping such a screw straight ahead, and as a rule, you can unscrew it later.

From the patents, there are descriptions at the top - after a few years without cutting you will not unscrew the screw

Cowboy zagrabie · Answer

I usually drill from the top first with a 4mm drill then 8mm in the screw head from the top. It is a waste of time teasing babola with baby olives. After 4 years of operation, if you need to disassemble it, it is better to get a new set immediately.

The cap underneath is embedded in the plastic, if it is standing there is no chance of unscrewing it. I advise against tapping anything - if the sink has an invisible blemish, it may crack. Do as described in post # 3, you can also try the option from post # 2- I have a typical invasive method> Good side cutting pliers, or scissors with narrow tips. A strainer is cut between the holes - operation time - up to 5 minutes.

In the past, such screws were nickel-plated brass and it was possible to unscrew it after many years. Nowadays, they are more and more often made of steel so that you can not unscrew it and buy a new set.

r103 · Answer

The screws are still made of brass or stainless steel. Because you can see them and they have to look nice :D

What you can't see, that is the nut embedded in the plastic into which the screw is screwed in, is made of ordinary steel - and there is "constipation"

kot mirmur · Answer

Standard, col. r103. There is nothing to think about here - everything has been written. Or you can quote a fragment of an old song from a radio column> Because good god, he has already done what he could - now you have to call a specialist.,

A properly selected locksmith's screwdriver.

You put a ring spanner on the screwdriver. You press it firmly against the screw and you turn the key.

Either you twist or you twist it. It's best to do this with a helper.

keseszel · Answer

Cut. I had a similar problem. The place to insert the screwdriver was created after several unsuccessful attempts. There was a reaming, the destruction of a contraption and a new one. Or try a new longer bolt later.

@diabeel had this minor problem over a week ago. He's probably dealt with it already, and we are still struggling with him here

diabeel · Answer

I coped. I had to cut it. WD40 could not cope. Maybe if I had played for two days it would have gone but there was no time Thanks for advice

karolark · Answer

I doubt it if it moved, it was most likely with a thread in the plastic
