3/16 x 1-1/4" Hex Head Concrete Screw Anchor, for Anchoring to Masonry, Block or Brick (100Pcs)

The concrete screws are fine. The light plastic box broke during shipment but what ever. Drivers fault or the packing in the boubble wrap envolope more at fault. It's not a case made to last, more to just get it too you. The drill bit looked like the one you get with the name brand that has a flat spot on the end to fit into adapters. I tossed it with a pile of bits so I'm not sure if I used the one that came with it. More often I use a different size and / or SDS bit. IMO bitss that come in a box is just an extra in case you forgot to get one, lost, wore out, or broke you others. Who would expect a common hammer drill bit to last 100 holes? Not realistic. Anchoring in concrete no matter the type or brand is a skill. Years ago before cordless took over we would set Tapcons with a corded drill that had a keyed chuck and no clutch. There was about a millisecond between tight, twist your wrist, or broke.

Yeah. These screws work well once the hole size is the correct.

If you’re looking for a budget-friendly masonry screw that gets the job done in concrete, block, or brick, the Bobibbi 3/16" x 1-1/4" hex head concrete screws are a surprisingly solid option for light-to-medium duty fastening.

A great example of a company trying to go the extra mile, but creating problems while doing so. The drill bit included will bend (if not melt outright) if you rely on it. The anchors are top-notch. Very strong age good quality. But, the drill bit is subpar and of a much lower quality. Make sure you get a separate bit that works with a drill meant for concrete.

Excellent product works great

This is the first time I tried to use Tapcon-type concrete screws and I was amazed how easily they screwed right into my concrete block wall. I used a small Black and Decker battery operated drill to do it and there was no strain or effort required. I drilled pilot holes first, using my DeWalt masonry drill bit and it was essential to do that. There is a masonry drill bit included with the screws but it looked like it wouldn't last long so I used my DeWalt bit but maybe the free one is better than I thought. I tried to make the final turns with a screwdriver and it was a lot harder, so maybe the key is to use a drill. Whatever, I certainly recommend these screws and would buy more if I need them.

I got these for mounting electronics gear on concrete walls in IT areas. Thy work well on most concrete but are not deep enough for crumbly concrete and mortar.

So for the money and number of screws they’re a good deal, especially over Tapcon prices. They’re solid, however the quality control could be better. I had like 3-4 that had blunted tips on them, so I couldn’t use them.

Excellent hardware!

Works well and priced competitively, significantly less expensive than walk in store option
