Hammer the screw in like a nail just a couple a couple millimeters before driving it.

Get yourself a bit holder with a guide sleeve (https://www.dewalt.com/product/dwairdg/ir-drive-guide-w-2-impact-ready-bits). Works for any type of screw since you load it with whatever bit type you need for your screw (in your case, torx). If you've never seen one, you'll love how easy it makes driving screws when they wanna fall off the bit/work.

Only real drawback is you don't have precise control of the angle the screw starts at but it's close enough for most work.

Generally with torx screws, you don't need much leverage. I suggest buying better screws.

For example, Spax torx screws have little razor blades on the tips so that when you are driving, they function as a drill as well. This means that you don't really have to apply force to them from the back.

Another thing you can do is use a hammer drill. A hammer drill will make short work of any of that.

Another option is to use a right angle adapter.

Additionally, the torx bit should fit in the screw head to the point that it kind of suctions in place like a Lego. Spax, as an example, includes bits in every screw box, and they are probably the best bits you can get.

Another brand (I don't like them as well but whatever) is GTK.

Use an awl to give it a little dimple to drive into.

I see a lot of good responses but id also like to add: Drill a hole first if you can. Use a bit smaller then what your screw is, and only drill enough to be able to slide the screw into the hole.

You could also do this with a hammer and punch tool, provided you can reach.

This also doubles as a benefit for wood, you're unlikely to split or crack the wood if you pre-drill the hole.

If you mean phillips head, then fins the right sized bit. they look similar but the right size grips the screw properly

Yes, torx screws and good quality bits. Bosch ones are good

I had a whole box of Simpson screws that did that. Try another brand
