47877 Construction Lag Screws, 5/16"-18 x 4", Epoxy Coated, Torx/Star Drive Included, Coarse Thread, Decking Screws, Outdoor Rust Resistant, Bronze, 100pcs

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 in place of the good old reliable lag bolts because they are touted as not requiring pilot holes. I found this not to be the case. The star drive works pretty well, but then so did the hex heads on the old lag bolts.

These lag screws have worked well for me. They are Torx drive and come with a bit. I haven't had them long enough to determine if the coating will last, but I am well pleased with how well they hold my lumber together and how strong they are.

These were pretty awesome. We used to affix cedar shutters and panels. The Golden color worked well with natural panels sealed with boiled lindseedoil.

First pack came open and missing screws returned and quickly got another one unopened good service fair price

Used these to build a bunk bed for my daughters. Drove in great with the supplied bit. I tested a few in scrap without pilot holes and they drove in very well. If you are within a couple inches of end grain I would recommend a pilot hole. Personally I drilled pilot holes for every one just to be safe.They are kind of a golden bronze color and matched well with the opaque whitewash stain my daughters picked.

These are EXCELLENT. We are building horse stables with true wood straight from the saw mill that measure exactly 2 x 6 inches going into 6 x 6 inch poles. We pre-drill the 2 x 6 and let the lag screw eat it’s way into the 6 x 6 for the other 2 inches. They HOLD those 2 x 6’s great, and look really nice. Each 12 foot treated non-arsenic 2 x 6 weight 40 lbs. The truss head on the screws holds perfect.

They did the job I expected them to do!
