I've tried telling Screwfix about this, but they don't seem interested.
In
fact the general 'shoddy goods' level from Screwfix seems particularly
high
at the moment - not sure if it's just me?!

Anyway - 'Standard Junction Boxes' - I've tried the 20A and 30A jobs
(13013
and 12802) and how these meet any relevant BS is beyond me. I've also
tried
replacements, on the off chance it was a dodgy batch, but same problem -
clearly a fundamental design fault. I know you get what you pay for, but
these are plain dangerous - don't buy them!

Basically the grub screws cannot be properly tightened since the
surrounding
brass socket gives way under any reasonable pressure. As can be seen by
the
picture below, this causes the screws to jump out their threads, creating
a
hot joint. Sometimes the thread will give way AFTER installation - so
even
if it seems fine initially, it can fail later down the line:-


Totally agree. I complained to Screfix some time after I had them and this
came to light but they didn't want to know. Threw about 5 away.

Also don't touch "I can't believe it's not nails" at the moment - the mastic
cans leak all the gloop out of the back onto the gun.

They really have gone downhill recently.
