Suitable replacement screws?

[Agile]

I have a dismantled Ikea Hemnes 8 drawer unit.

Most of the screws used are 4 mm allen screws 50 mm long and with a thread OD of 6.9 mm.

But about 10 of the screws need to be longer at about 70-80 mm.

Now this is the funny thing but I dismantled the drawers and ALL the screws are just 50 mm long.

Trying to find screws from Screwfix or Toolstation but they don't seem to have any very similar at all.

The Ikea instructions don't help me either as they don't give the dimensions of the screws used.

Anyone know what is wrong and where I could get some screws to fit?

Thanks

Tony

Wow, that exactly what I need.

But was somehow hoping to get it by Friday locally from Screwfix or whatever.

Box of screws in store would be good if they really had one but that sounds a bit hit and miss when the over populated store at Neasden is involved. It can take an hour to park there.

But thanks for your help, at least I know what they are called now and will order some and see when they arrive!
