If they are similar to concrete screws with a torx head, then yes i have.Noseall have you not used them Raiperstar fixings as you can just drill straight through the timber into the wall with 6mm sds then fixing job done solid.
Hammer fixings are waz.
Use a 100mm, ≠6 screw with brown plugs and a 7mm bit.
It may have been wise to have stated that you are fixing the timber through the 100mm as opposed to what everyone else was thinking ,i.e. through through the 50mm.Should the screw be longer than 100mm?
the timber thickness is 100mm already.

Why are you fixing it this way?
I'd use 150 x 8mm thunder bolts with the hole for the head forstnered out. One every 1.2m or so.
Yes do the hole prepping first.
Drill a 25mm hole with flat wood bit or a forstner about 12mm deep followed by a 10mm hole.
Then 8mm for the thunder bolt. Piece if cake.
Easily adjusted back too if you need packers.
Try and get flanged head thunderbolts. If not just use washers.
Is this to cut down on noise from a party wall?putting up 100mm thick acousti insulation and covering with double plasterboard.
The spirals on the fixing will be 10mm or there abouts. A socket will be best for tightning.
Drill 11mm if you find it binding on the wood.
