Review: Screws That Keep the Roof Over Your Head - I used the Power Pro 47877 Lag Screws to screw down plywood for a roof, and guess what? They worked! The roof didn’t fly off, which, in my book, is a major win. The star drive made installation easy, and they bit into the wood like a champ. Will they rust? Honestly, I don’t think so—they look and feel like they’re built to last. But hey, even if they do, the roof’s still up there, so mission accomplished. If you need reliable screws that won’t let you (or your roof) down, these are the way to go.

### ⭐⭐⭐⭐⭐ The Best Lag Screw For Deck Fabrication And Rebuilding
*by T***R on October 30, 2020*

I have used the Hillman fasteners on my deck rebuild project for the understructure and for fabricating new support in places as well as on 4x4 posts to fasten to the deck sides and other parts of this project. They do not strip. I drill pilot holes first. They also do not break. Do NOT use one of the cordless impact wrenches on these. We had a carpenter who used one of those impact wrenches to install regular old furniture fabrication screws and many broke off in the finished wood, causing me to have to drill them out and patch the wood surface to fix it. Just use a cordless driver on them, and pre-drill pilot holes, and you will have no issues with them. Excellent quality fasteners.
