Description

Applications The anchor is made from Carbon Steel, and is Blue. This anchor is designed for use in Concrete, Block, and Brick. Environment The anchor is designed for use in a Dry environment. Head Style The anchor is a Flat Countersunk Phillips head and is designed to prevent the head from protruding above the surface of the item being attached. Hole Diameter/Bit Diameter The anchor requires a 3/16" hole to be drilled in the base material (Concrete, Block, and Brick). The hole should be drilled with carbide tipped bit that meets ANSI standards and used in a hammer drill. Driver Required A 3 phillips bit is required for driving the anchor into the base material. Diameter of Anchor The diameter of the anchor is 1/4". Length Anchor The length of the anchor is 2-3/4" Thread Length The length of the threads on the anchor is 1-3/4" in length. Minimum Embedment The minimum anchor embedment into the concrete is 1". Therefore, the anchor must be installed so that a minimum of 1" of the anchor is embedded into the concrete. Maximum Fixture Thickness The maximum fixture thickness or the maximum thickness of the material being fastened for a anchor is 1-1/4" to 1-3/4". This will ensure that the minimum embedment of 1" will be met. Fixture Hole Diameter The hole in the fixture or material being fastened must be larger than the designated diameter of the anchor. The 1/4" diameter anchor requires the hole in the fixture to be 5/16". Spacing between Anchors Each anchor must be spaced a minimum distance of 4" from each other when measured center to center. Edge Distance It is very important not to install the anchor any closer than 3" from an unsupported edge of the concrete.

    • Great quality
Size: 1/4" x 3-1/4"
These are good screws. Has good grip and it did the trick. Make sure you use the correct bit. I didn't use this bit because I used a SDS plus to make a hole before using these screws.

    • Good price for masonry screws!
Size: 3/16" x 1-3/4"
Very nice masonry screws! I was able to fasten some shelves and a water filtration system to my cement basement walls! The included drill bit works very well and makes installation a breeze! Very good quantity for the price as well!

    • Good screws lousy drill bit
Size: 3/16" x 1-1/4"
These screws work fine on real rock but are useless on engineered stone used on most homes nowadays. I fastened screws tight on my flag mount then a few days later the mount and flag are lying on ground. Screws vibrated/pulled out with a powdery residue left in holes and on ground from the fake stone. If you use these on engineered stone then use anchors. So far so good. ... show more

    • As Good Or Better Than The Other Blue Screw
Size: 1/4" x 3-1/4"
Just finished installing about 50 of these into a poured concrete wall and not a single broken screw. Only two screws "spun out" and didn't grip the concrete, once where I was repeatedly trying to drive it deeper so the head would sink into the wood. The other was a hole where I hit rebar and had some trouble drilling the hole, probably not the fault of the screw. If you are using these flat heads to avoid the screw head from protruding from the wood, you will definitely want to use a countersink bit in the wood you are attaching to the concrete. I went with a slightly oversized half inch bit and it worked perfectly for me. Without it, the head will protrude and trying to force it deeper will cause the screw to spin out as I mentioned above. I didn't try the drill bit that came with the set, instead using a Milwaukee MX4 bit with one bit surviving the entire project. ... show more

    • Excellent quality and very strong
Size: 1/4" x 2-3/4"
These are excellent quality screws for concrete work. Drilled the 3/16” hole with my hammer drill and they screwed right in. Did about 45 and not a single one broke or stripped the head. I will say that although the drill bit came with the screws it is not a high quality bit. So if you are going to be drilling a lot of holes you would do well to purchase a higher quality bit. After about 20 holes I noticed it did not cut into the concrete as well. I changed the bit and I was back in business. ... show more

    • Good screws at a good price
Size: 3/16" x 1-1/4"
Screws hold in brick just fine. The included drill bit also works, but you must use a hammer drill. A standard drill will not get the job done.

    • Good alternative to Tapcon, but be careful
Size: 1/4" x 2-1/4"
I used their hex head for another project, they were great. I needed something to sit flush for this next project. I estimated that I needed 50-60. I stripped the head on so many that I went through all 100, and needed another 20 so I bought Tapcon with their Torx head. It was so much better. If you need flush, get Tapcon. If you can get by with hex these are very much a great alternative. ... show more
