Hordion 100pcs Hardware Nails 1 inch, Carbon Steel Point Tip Cement Nails Masonry Nails for Concrete Brick Woodworking Picture Hanging

How do you fasten to fiber-cement (Hardy Board) trim-work? I had to secure adhesive-backed velcro strips and regular nails would not penetrate fiber-cement trim-work. There are two obstacles to overcome:1. Predrilling holes for small nails requires small diameter masonry bits which are brittle and hard to find.2. Regular steel nails break off or bend when hammering directly into fiber-cement trim.These "Hordion 100pcs Hardware Nails 0.79 inch, Carbon Steel Point Tip Cement Nails Masonry Nails" can be hammered directly into the Velcro/Fiberboard without predrilling holes. I inserted 16 nails without problems. See picture.

These hold up well when used in concrete. Their lightweight but but do not bend when I hammered them in. I still have many left over for other diy ideas.

We have concrete blocks walls and these worked very well although they did still cause a buckle or small chip.

Nice sharp nails.

Perfect for hiding with dark decor on wall.

Exactly as represented.

Don't waste your money! I bought these specifically to hang pictures and lightweight items on a basement cinderblock wall. They only penetrate maybe halfway, 3/8", and no further, no matter how hard you hammer them. Sometimes they go straight in and hold, sometimes they chip and flake the concrete so deeply that the nails fall out. Six out of ten times, the head snaps of the nail as you're hammering. Very disappointing.

They were too big for string art which is what I needed
