Your cart is empty.This products has features that are both impressive and unique. Topping the list is the new "Star Drive" technology which virtually eliminates campout for a smooth, effortless drive every time. Chances for splitting wood are greatly reduced by the patented cross-cut threads and the wood biting cut point. These two features combine to prevent wood splitting by grinding wood and removing fibers from the hole.

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.

Difficult to start screw into wood so needed to predrill hole to get screw to go in. Once I started doing that it worked great, just a pain to do the extra step

Did not bite into wood like others I have used, poor fit on both the supplied bit as well as mine, made screw wobble and harder to start.

Got these after they dropped price and they were a real bargain for what I needed. Used them to hang vinyl/plastic shutters on our home after the silly plastic anchors failed. The 4" length was needed because the previous homeowners placed 1" foam under the vinyl siding they installed. The shutter, siding, and foam panels combined to ~2.75" of thickness so I thought that a 4" screw would be perfect to bite into the original wood siding. Since our shutters are painted black, I stuck the screws into a big piece of cardboard and then spray painted them with several coats. Rehanging our shutters allowed me to get them aligned better and now I have no doubt that they will remain in place until myself or the next owner chooses to remove them; which will be easy since they are just massive screws. A point of caution, beware of wasps and hornets when removing shutters or other siding from your home. I found two nests and thankfully was able to spray them with foaming insecticide. Not much fun when you're high up on a ladder where all your neighbors can judge you. Finally, I recognize that these were overkill for shutters, but they provided the large button-head look that my wife liked, and I ended up with quite a few extra that will be used for more appropriate construction projects in the future.

I used these screws on my redwood fence. I used steel brackets to hold up the rails, and used these screws to attach the rails to the brackets.First thing I noticed, the torx drive that comes with the screws doesn't fit well into the screw head. They don't seat well and you'll likely slip out of the screw head numerous times. You have to use your free hand to control the screw as you drive it in or it will end up angling into the wood badly. I ended up taking the screw to my local hardware store and finding a better driver that sat well in the head. Huge improvement.The other problem is that the "pre-drilling" effect of the screw can really tear up soft woods like redwood. You have to go very slow at first or you will strip the wood out and won't get a good, snug fit. The first 1/4" of the screw is very serrated to help it drill into the wood. This is good for hardwoods, bad for softwoods. I didn't knock the star off for this though. I took off a star for the driver being lousy.
