Best method of constructing Kitchen unit carcasses?

[peca27]

Mate is just getting a Kitchen installed, went around last night + noted that all the wall units are through screw fixed from the side? The installer has then fixed a coloured end panel to hide the through screw fixings? Looks very untidy in my opinion.

I went home + checked my units? They have an underside through fixing (I presume dowelled) which is hidden + looks much neater.

What is the standard UK-wide construction + which is better in the long run?

I've had my Kitchen 25 yrs + never had a problem tbh

Sounds like he has the cheap Wickes cup's [off the shelf] they are fairly weak due to that construction method, you gets what you pay for.

Thanks for that foxhole

So this through fixing method is not a good joint long term then?

Am I correct in assuming you would normally have a metal dowel + nut joint?

Most use the dowel and metal fixing but cheapies from Wickes and Ikea use the basic screw method. The screw often fails to bite into the chipboard interior and come loose, if I fit those I use an extra couple of chipboard screws or a dab of glue.
