To those of you who build cabinets, do you have a preference on what size Confirmat screws you use?

I was going to buy a bunch of them online through mcFeelys, but they come in 2 main sizes it seems: 7×50 mm and 5×40 mm.

Also, do you need a different drill bit for each size? They’re not cheap.

Should I stock up on both sizes or just stick with one size for most applications?

Thanks for any help!

My understanding is confirmat screws are used with particle board or MDF.

I guess the 7×50 is for 3/4” stock and if that’s what you use I’d go for the 7×50
with the matching drill bit accessory.

What he said. You could use them in plywood but no need when assembly screws are cheaper.

You need very specific sizes of bits for different
materials with confirmats. Make some calls
if needed. My boring machine works for
confirmat holes in ply and MDF but that’s a
lucky setup… some setups could work with
ply but split MDF so better safe than sorry.

Have your say...
