Solid Anchors for Heavy-Duty Jobs
I liked that these concrete screw anchors are sturdy and reliable. The 3/8-inch size provides excellent holding power for heavy fixtures, and the screws bite into concrete cleanly without stripping. The pack of 30 is convenient for larger projects, and the included heads are well-machined. What I didn’t like: pre-drilling is essential, and if the hole isn’t perfectly sized, the screws can be hard to drive in. Also, they’re a bit pricey compared to similar options, but the quality makes up for it...

Not much to say about these bad boys. They are strong, go in easy and grab the concrete well, and helped me anchor and bolt a doorframe to a cinderblock / concrete wall. You can feel how heavy duty they are just by holding one. Highly recommend!

Good concrete anchor.
What can I say? It is a concrete anchor. We used these when installing a new outdoor lamp post. They work well.
