I need to put down a threshold from carpet to hardwood which both are on a concrete slab. The space in between the carpet and hardwood is about 1/4 inch. The threshold I have has the holes in the middle for the nails to go and of course it hits in the space where the slab is. How do I put this down on the slab? The nails just bend and don't go in the slab.

Install plastic shields first. The plastic shields are intended for use with small screws in drywall but they work well. Look for small “blue” ones. They are about 1/8” diameter.

Using the threshold mark the hole location. Using an 1/8” masonry bit bore holes for the anchors. Hammer the anchors in. The proper anchors will fit tightly in the hole. Install the threshold as usual.

Use masonary nails or tapcon screws. Screws require predrilling, but usually causes less damage and hold better. Of course there are powder actuated nailers, but that is usually overkill for a carpet strip.
