BCP Fasteners 100 Qty 1/4" x 1-1/4" Hex Head Diamond Tip Concrete Screws to Anchor Masonry, Block & Brick (BCP498)

These worked great, they are holding up some tool hangers in my cinderblock wall.

Worked great for securing my pergola to the concrete patio.But the drilling slowed down after the first dozen holes .

These screws are basically generic Tapcon screws. They work just as good but are cheaper

Screwed these into brick to hold some gutter downspouts and they seem to hold well.

Screwed my fireplace doors into the face of the fireplace. These are nice as they come with the drill bit to predrill the holes out.
