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 Hex Washer head and is designed to allow the head to sit on top of 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 5/16" 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 2-1/4" 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 3/4" to 1-1/4". 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.

Good screws, but the included bit is garbage
The screws themselves are decent - they hold pretty well and tap in fairly easily. The large socket head makes them easy to drive, although would need to be counter sunk manually if you don’t want them to stand proudHowever the included bit is utterly useless - mine twisted ridiculously when halfway through the first hole I tried to drill, and the concrete I was fixing into was not even particularly hard! Fortunately I had another bit of the same size, and could continue with that...If you buy this, I recommend also buying another high quality bit

Not suitable for breeze blocks
bought two different sizes of these to fasten into breezeblocks. Neither size would take a hold, ended up having to raw plug and use screws.

Great, no plugs required
As long as you are careful choosing the correct drill, then these screws are superior to screw and plug.

Decent
Used two boxes of these to put up some stud walls. Bottom studs are going into concrete floors and these fixed well and not had a single one break or snap, great for fixing 2x4 to the floor with DPC sheeting underneath.Coating should stop erosion but it’ll be a while before we find out!
