Blank Nut ½ x is rated 4.9 out of 5 by 11.
Rated 5 out of 5 by from Great for radiator valves I bought a couple of these to seal off thermostatic radiator valves which dribbled when the radiator was removed. The nuts come with rubber seals so you don't need to buy anything else. Just fit and tighten. No dribbles!

Rated 5 out of 5 by from Perfect for Rads Used on rads that were removed for decorating. Perfect fit. May need these or the 3/4" size.

Rated 5 out of 5 by from Handy I always use for temporary shut offs when removing radiators or to stop debris falling into tops of isolators etc.

Rated 5 out of 5 by from Should have gone to screwfix Tried loads of places to get this ! Just needed to blank a shower tap. Checked online and bingo. Just be careful with measurements 1/2 or 3/4inch

Rated 5 out of 5 by from Panic Reliever The plasterers had started when a shout came, leak in the hall ! Oh no. As I ordered this product to 'click and collect a second voice said 'leak in the bathroom' Oh no ! No problem. Screwfix had the answer in stock. After a no fuss collection I was back fitting the product to stop all leaks......instantly. No damage done. I will keep these in my plumbing box for the next decorating session. Thank you Screwfix.

Rated 4 out of 5 by from Does The Job I initially bought the wrong size for my radiator valves , based on exact measurement of thread on valve, as I didn't realise that the blank nuts need to be a size smaller!! However, correct nuts obtained and now all valves blanked off for decorating as intended.

Rated 5 out of 5 by from Perfect for capping I had removed a radiator in order to paint behind it. Unfortunately, even with the valve fully turned off, there was still enough of a drip leaking to cause a puddle. This was perfect for the job. Just had to screw it on finger-tight and it stopped the drips instantly.
