What size fixing?

[soda]

Fitting a new kitchen over the next few days, mainly as I'm a cheapskate but it's a little outside my usual comfort zone of spanners and socket sets.

The wall units only have 2 holes at the top to mount to the walls, I'm thinking a small strip of wood along the wall to set the bottom of the units on and 2 large screws/bolts for the top. What would be a suitable size for these screws?

Depends on your wall. If it's breezeblock like mine then I'd say 2.5" x 8 - but make sure you get the hole and rawlplug right so it's a good tight grip. The top is trying to pull forwards but most of the force is a downwards sheer, which a horizontal screw will resist well.

Use a bit of soap on the screw to help it screw in.

Did your wall units come with these? They should do the job on their own quite well but if you're without an extra set of hands, the timber strip at the bottom will help take the weight while fixing.

You make no mention of the wall type you are fixing to. Solid block or dry lined over block. This will have a bearing on the length of screw needed to clear the void and have purchase in the blockwork.



I'd imagine about a size 8 would do, probably about 2 inch for direct into block and 3 to 3.5 inch if clearing a dry line void. By the way, I fitted my own kitchen and I found one of the little Bosch palm drivers were priceless.

HTH, PP.

Edit: Simpo two is a much quicker typist than me. Sorry to repeat his reply.

Is there a timber/chipboard strip across the back of the units near the bottom? If so, drill through an extra couple of holes and put two more screws in.
I'd use brown plugs and for a tight fit I'd go upto a 10 gauge screw, either 2 or 2 and half inch screw.

Cheers guys

It's solid block so straightforward enough, I'll leave the strip of wood at the bottom for some support as the trim at the bottom of the units will hide it nicely.

If it turns out like I'm planning I might even throw up a few pics.

I used 4'' frame fixers (£18 a 100 from glazing suppliers) to fit mine. Basically drill a 6mm hole 5'' deep, they then self tap into blocks/bricks using a torx driver on drill. Strongest things I have ever used, they could take a huge weight & good value!
