3/8" x 3-3/4" Wedge Anchor, for Cement and Concrete only, zinc-Plated Carbon Steel Screws and lag Bolts （ 100 pcs

Came in accurate size and dimensions according to the listing. Worked as described and is holding strong to secure a 6x6 inch post 7 feet tall to a cement base. Easy to use, just hammer drilled the holes to correct size, tapped them in with a hammer and done. The mounting plate for the post would break before these anchor bolts come loose, they are that securely fixed once hammered in. Did not rust yet, hopefully they never will, it’s been a week and they are still shiny like new after being rained on several times.

These work great for concrete anchors and well worth the money

Worked very well to anchor metal plates to concrete.

Interesting winged model that expands as tightened nut rises. Placement depth in the anchored piece (4x4” horizontal post) is important in determining the length of the anchor needed. I ordered 4.5”, but now see the need for 3.5” for my application. Ex: anchor is 1.5” buried, leaving 2” of threaded stem, which will rise 1/2” in a 3.5” 4x4 when tightened enough to spread retaining wings in cement. That leaves you 1.5” to bury the threaded stem below the surface of the 4x4, for a cleaner look.

Great product and works great!

The items were fine but I ordered 100 pcs and only received 50 pcs. Still waiting for the other 50 pcs. The sticker on the bag listed 100 pcs but there are only 50 pcs in the sealed package.

Great value, worked perfect

Used for a 10k lift. New drill bits and can't get 150ftlbs. 60 to 80lbs and threads keep getting taller! Wish me luck!
