100-Pack of SNUG Fasteners SNG482 3/16" x 2-1/4" Flat Head Phillips Diamond Tip Concrete Screws

ChadsReview: My Plastic box came "complete" with Drill bit and Masonry Bit included. I have a concrete Construction home and Use these all throughout the house. Probably 40-50 of them ... Not a single 1 has snapped.. broke off or otherwise. Reviewing other peoples issues in their pictures you can clearly see the Screw's threads have been sheared off.. That's an indicator they are using the wrong masonry bit OR.. they are "drilling" through something other than concrete First... These are "CONCRETE" screws .. If you are "drilling" through wood first you need to use a "Wood" bit and THEN a concrete Bit after you pass through the wood.

R. Maigret: I used ~25 of these to fasten 3/4" plywood to a concrete foundation wall. None broke, but I did spray some lubricant into each hole to reduce the force required to tighten the fastener.

I only award 4 stars because the included masonry drill bit appeared to be a "dollar store special" and only managed 3 holes before the cutters were completely worn away. Had I known in advance, I would have ordered a decent drill from Amazon along with the screws.

Amazon Customer: Had to use this product to drill thru drywall to get to concrete block in order to hang a full length mirror. Studs were not where I needed and the space between the drywall and concrete block was so tight that a moly bolt or other screw securer would not fit between the two. Success!.. This product even comes with the correct size drill bit for the screws.

Colin R.: I've used these concrete screws for securing portions of my basement sub-floor. Overall, they're quite good at doing what they intended for. They have good bite and holding. The only area I found I had to be more mindful of was when using my Dewalt impact driver, some of the screw heads would snap off as they became seated. I found that by reading the feedback(amount of resistance) from my impact driver and in some cases, then enlarging the specified pilot holes, would alliviate most of those issues.

rockshi: I absolutely love this product! I used only these concrete screws to install about 1500 square ft. of sub-flooring for a basement. The cost was roughly 1/3rd the cost of using only Tapcon concrete screws. These screws were of amazing quality, and in total I broke 2 screws for the entire basement. Keeping in mind that I went through 4 concrete drill bits to finish the flooring, 2 broken screws really is nothing. The package also includes drill bits, although the ones included are okay for the average job, I would recommend picking up higher quality bits if doing substantial work.

Amazon Customer: I have only used two of the screws. It was into mortar between bricks. They worked well.

C. L. Hutchins: The fasteners worked well when used in applications they are specifically designed for. Using the pilot drill bit is key to ensure they go in tightly and do not break off during installation. Overall, they are a good product and easy to use.
