Firstly, I assume you're dealing with household (kitchen type) cabinets. Your question has to do with what affects shear strength of Tapcons. Data necessary to resolve your dilemma can be found at http://www.barnhillbolt.com/specs/TapconPerform.htm OR https://www.itwredhead.com/portals/0/fmproductcatalog/documents/products/37/tapcontechnicaldata.pdf OR https://www.confast.com/technical-specifications-for-tapcon-concrete-screws/ OR https://images.homedepot-static.com/catalog/pdfImages/c0/c063f0ba-e028-42fd-9652-a519dfcf1198.pdf. Simply put, the weight of your cabinet sections determines the number of properly embedded Tapcons you need. This (conservatively) neglects friction imposed by clamping forces (from properly torqued screws) drawing cabinet backs against the wall finish. Of course, cabinet backs must be robust enough to resist those shear (downward sliding) forces. At this point you'll want to consider whether the screw heads will pull through due to eccentricity. (Distance to center-of-gravity from wall will cause overturning moment producing prying action away from wall.) Washers, anyone? I'm confident the tensile (pull-out) capacity of the screws will be adequate for household cabinets. Check the referenced tables. Industrial shelving would be a different matter. If the sliding criterion is not met, you can install a shear rail (cleat) beneath the cabinets which is akin to permanentizing the alignment rail you used to set their height. Admittedly, there is little information about the effect of cantilever (shank length under the screw head assumed not supported by the wall finish). However bending deflection, due to same, somewhat is limited by the compressive strength of those finish materials. It would be interesting to pose this esoteric to the manufacturer and request a table of load factors. But, unless I were hanging mission-critical or vibrating / shock-loaded equipment on a steel plate (and I'd use undercut anchors or cast-in-place embedments for that), I'd rely on the product safety factor and my rounded up number of selected fasteners to cover that eventuality. Also, for a few cents more, one can use the next bigger size fastener for added peace of mind. If you have a scientific bent, test load the installed cabinets. And, by the way, when calculating the fastener layout, don't neglect the weight of contents - pantry provisions, dinnerware and stoneware are not light!

I bought these a few weeks ago to secure several pieces of plywood to some brick surfaces. After pre drilling the pilot holes with the recommend drill bit size listed on the outside of the container in the instruction area, the holes were too large and the screws could not grip the inside of the hole and the plywood is still loose. I was very disappointed.

If you are anchored in concrete block I wouldn't recommend removing and reinserting. The block is not homogeneous and chances are you will never get it to seat again. Solid / poured concrete might be a different story but block, no.

Since we don’t know the strength of the material, we can only reference (2) documents for your use. These documents outline conditions such as spacing requirements, etc. to get certain loads. 1.

Blue is Best
These are good concrete screws but if you’ve never drilled into concrete don’t get frustrated when you break them. 3” into a slab will put a lot of stress on this fastener and the concrete has no give unlike steel or wood. Drilling into CMU block you won’t have much trouble but poured concrete is much tougher. Also results may depend on your location as concrete may be harder or softer due to local geography and aggregate mixes. Be prepared to break 1/4 of them in hard concrete

Has many applications where masonry anchors are cumbersome. Tapcons provide lots of holding power expediently with little effort and less clean-up. They offer several diameters and lengths, so one can select the required shear and tensile capacity. (Though I've used overkill on occasion because I had another size on hand...they're economical.) Correct drill size is important - Do use the recommended drills; and replace as needed. Running them undersize may cause the screws to break... In preference to drop-in (sleeve) or undercut (wedge) anchors, I use these for light loads such as routing utilities (See photos 1 and 2,) and shelving (See photo 3.), and medium duty loads such as light ductwork / piping. (See photos 4 and 5.) No anchor installation is completely reversible, but relocating or removing a Tapcon-affixed bracket leaves only minor defects in the masonry - readily patched or sealed if necessary. Tapcons also are treated to resist corrosion. A higher grade 'Ultrashield' is offered as well as stainless steel. Also advantageous is the Tapcon Installation Kit which quickly adapts the drill and driver bit being used to a single tool.

I used these to install a door handle on a solid concrete foundation. The anchors worked great. I would agree and skip using the drill bit that comes in the package. I used my rotary hammer drill and bit to bore the holes and an impact drill to install the screws. Even though these are Phillips head, they didn't strip. I use this handle to pull myself up and out of the drivers seat of a very low slung car. after two seasons, the screws are rock solid, the handle has never moved.
