TR TRUE screws

[Claw5]

Getting ready to install a TRUE.
When I thread the screws into the back plate (just a trial fit, right out of the box) they do not bottom out. In other words- the shoulder of the screw is not flush with the back panel when 'finger tight.' It doesn't seem that the threads are cut all the way through the base plate.
Is this by design?
Should I just go ahead and tighten the screws until they bottom out?
Thanks.

Tighten until they will not turn any further. Keep in mind that even when fully tightened down, the heatsink will move/wiggle a slight bit. Don't be alarmed though, it shouldn't impact cooling. If you feel that it does, however, you can get a washer for a dime at ACE Hardware and stick it between the heatsink and the hold down scissor-plate to improve pressure.
