While the US Anchor Drive product is more expensive than the alternate products, the added security of knowing that your plate is securely fastened into the concrete floor is well worth the additional expense. Please note that if you are planning on using this product, you will need a hammer drive drive and concrete drill bits. Additionally, I would recommend using a spade bit so that you countersink the anchor especially if you plan out placing your pre-built wall on top of your base plate.
With the price I paid for a bag of 100, these are the most economical choice that works and looks good too. Just make sure that you use a heavy hammer to drive these down as the flare at the end of the anchor does present a good bit of resistance, which is the whole idea.
Obviously you will need a hammer drill with a good masonry bit. You'll need to drill through the stud and into the concrete (make sure you wear a respirator, as concrete dust is not good for your lungs). I'd strongly suggest you shop vac out the holes after drilling. If there is dust in the hole it makes driving the nail home much harder.
Once you get it drilled you pound the anchor in place, which does take some strength. Once it is in it is dead-solid. I couldn't remove one of the studs with a 4' pry bar.

PRO: As expected holds strong. Was able to pull up 2x4's anchor'd to the concrete with the 2x4 splitting and anchor not budging from it's location. Read morePublished 3 months ago by thisn00bagain
Entirely useless product. These nails bend when you start driving these in the concrete. Ended up using Tapcon which, btw, can be used on PT lumber too.Published 15 months ago by WhoLetTheDogsOut
