53Pcs 1/4 x 1-3/4 in Concrete Screws with Drill bits,Masonry Screws for Concrete Assortment Kit,Hex Head Block Cement Stacoo Screws and Anchors,Diamond Point,Blue Coated(1LB)

We have a flag pole mounted to a brick wall, outside of our front door. I noticed the other day that the mount is getting loose as the screws were never put in tightly to start. So I planned on removing and getting new concrete screws to remount the holder. I searched out concrete / masonry screws and this option came up as a decently priced product. I ordered these up and they arrived in a few days.I liked how the screws came in a convenient case along with a drill bit. I used the drill bit and was able to screw in the screws tightly and now my flag pool is as tight as can be. I ended up using a socket to tighten them down vs the regular screwdriver. As noted on the packaging, be sure not to let your 5 year old use these screws, but a 6 year old should be fine… For the price point, the amount of screws you get, and the durability of these screws, I would certainly recommend them and rating accordingly.

Ever since I discovered the "direct-drive" masonry screws, they are the only thing I use for masonry applications with brick, concrete, and stone. I find them extremely reliable, easy to use, and suitable for almost any application. These Krysay screws are very similar to the Tapcon screws I find at the orange big-box supply store, and which I use extensively. This type of screw is available with either a Phillips head or a hex head; I always buy the hex heads as they drive much more securely than Phillips. I used these Krysay screws to fasten the 1" pressure treated treads to the concrete steps in my cellar bulkhead entrance, and they worked perfectly. I also used them to fasten several sets of shelving to brick and stone walls in my cellar. These screws came with a 3/16" masonry drill which proved to be poor quality, so I'm giving them only 4 stars. I like these Krysay masonry screws and I expect you will too.

These 3/16" x 1-1/4" Masonry Screws are blue. they coulda made them yellow, or red, or green, but they chose to make them blue. funny that.Anywhos, this Concrete Anchor Kit is substantially the same as the name brand, holds well once inserted and tightened properly (don't forget to blow out the dust before insertion). The Hex Head Screws are listed as useful in Block, Cement, and Stacoo (although how anything holds in stucco is a crapshoot - I always drill past the stucco and into the sheathing).Only time will tell how the blue ruspert plated carbon steel will hold up to weathering and corrosion.Two things - I'm not sure how you could fasten the phillips countersunk head version without ruining several screwdrivers.Also the plastic tray supplied to store these is kinda flimsy and prone to spilling out all 235Pcs onto the floor if not careful. They immediately found a proper home in a covered bin like all fasteners should come in.

These concrete tapping screws are my go to product for installing items on brick, block and concrete. The high low threads, used with the right size drill, bite into the masonry and lock down securely. I have better luck with the blue screws than lag sleeves or expansion bolts, and they don't corrode or allow water seepage in exterior use, unlike the older systems. I live in a brick house with a block basement foundation, so I use these frequently. Unfortunately, the retail chains seem to think these fasteners are a high markup specialty item, and the cost of 100 of this size of screw at retail would run $30-40 easily. Thanks to Krysay for not price gouging and delivering a quality product at great savings.

These screws are an obvious Tapcon brand alternative and they seem to work well. The threads did a fine job of tapping into the concrete, but only time will tell if their Ruspert coating holds up as well as Tapcon’s Climaseal. None of the screws I used snapped nor did the heads strip out, nor did I see any other obvious signs of inferior quality. Only time will tell how they hold up outside though.Oh, the included bit is trash - 4 screws for me and it was already in hospice care. If you are buying these for a project where you are going to be using these screws on the regular, do yourself a favor and also order a decent masonry bit, if you don’t have one already.

I don't like being too nit-picky, but that's kind of important to me. These screws are supposed to be 3/16's of an inch in diameter, but they're not. They measure .2085" or 13/64's". If you're going to build a part, build it right!Krysay's concrete screws are made to compete with a major brand sold in America I'll call "Brand T" shown in a photo I've attached. Brand T's threads, on the right, are variegated and much more aggressive in my opinion than the Krysay screws, on the left. Does that make them actually better? I don't know, but I have used Brand T for many years without problems. I will put Krysay screws to work in a non-critical application and see if they perform up to task.Screwing shelving or planks directly into brick or concrete block has to be done well, or failure can easily occur. Until I have tested these screws, I am going to only rate them as "average" or 3 stars.

These are very familiar concrete screws. They held up to a garage floor project I had without deforming or breaking. The price is comparable to other concrete screws I have used in the past.

Not much to say here unless something crazy happens and snaps the screws in half.In that case my first priority will be to update this review.Then I will attempt to fix my house.Priorities.Verdict so far:- they are strong. I cannot snap them in half with my hands. This is a good sign.- they fit comfortably with my drill bit. This is also a good sign.- They are aesthetically pleasing to look at. My gray and black screws are embarrassed. As they should be.- they appear to do what they are supposed to. This is certainly a good sign.Can't complain. Decent screws, decent price, and my house is still standing.May the odds be ever in your favor.
