3/8x4 50Pcs Inch Standard Fasteners for Heavy-Duty Zinc Wedge Anchors for Cement and Concrete

Work great. Good quality

Anchors worked good. Fast shipping. None broke or pulled out. Washer could be a bit more sturdy as they did deform some but none failed.

Great price for quality anchor. Used to anchor metal carport installation.

Heavy duty. True to width. And seriously easy to use. Drill a hole with an impact drill and masonry bit, hammer the anchor in, and tighten. It's as easy as my ex was with her betrayals...but let's not digress. But seriously, if you don't have a Ramset or can't use one for whatever reason (like a client that doesn't want to hear it), these got the job done with confidence that the shower curb we built will survive Armageddon. We tested the first one by inserting it into the foundation, and then tightened the nut (with the washer on it). It literally created a hole through the wood and went through it. Talk about impressive, as some of these anchors can't actually survive a test like that. These are seriously hardcore and work well for us.

Works great

The anchors were accurately described. They met the all the capability. Well made and durable.

I was impressed with how well these worked for my basement finishing project. I needed something to attach the treated 2x4 bottom plate to my concrete slab. Tapcons never work correctly, and I didn't want to invest in a powder-actuated nailer for the rare cases I need to attach to concrete. These were almost as easy as a ramset: I just stood on the positioned 2x4 (construction adhesive already applied to underside), drilled through the wood into the concrete with my hammer drill, nailed this through the hole and tightened the nut. I was able to tighten the nut to the point that it and the washer started to sink though the 2x4 and glue squished out from under the board. It held so tight to the concrete that I probably could've tightened it until it split though the board and/or stripped out the threads, so it was more than sufficient for hold down. This was in an older (cheap) slab, with areas where it was probably 2-3" thick at best. I was afraid the fastener would need to bottom-out to latch properly, but I had zero issues with hole depth or anything. I even got lazy and wouldn't clear out all of the drill dust, and these still held like magic. I'm ordering more now that I know they work for my use, and they'll be my go-to for concrete/brick anchoring in the future.

These fasteners were exactly what I was needing. Excellent quality and easy to install and the value aren't bad either. Yes, I would these again in the future.
