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

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.

Drilled a 1/2” hole, drove anchor in, and tightened. Work very well, secure, and easy installation. Seems to be quality anchors at a budget price. Would definitely buy them again.

Great product, easy to install and they work like they should. No problems whatsoever.

Exactly as advertised. Torqued em down right and still holding. Great for the price.

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.

I used these anchors for a concrete project and they worked perfectly. The zinc finish feels durable and the fasteners hold really well. Easy to install and a good value for the pack of 30 pieces.

The concrete anchors were very useful in a house project. Very easy to install, material is good and they provide a really good support. I will definitely recommended
