Customer Reviews (4.6 / 5 · 5 reviews)

Matthew U. ★★★★★

These held tight when I mounted a heavy shelf bracket into old basement concrete, no pilot hole needed for the 1/4" size. The zinc plating looks clean and none of the hex heads stripped out on me.

Sebastian S. ★★★★★

I was a little worried the hex head would strip under torque, but these Tapcon screws bit into the concrete beautifully and held firm. The zinc coating looks clean and should resist rust well in my garage.

Nicholas ★★★★★

Picked these up for securing shelving brackets to a cinder block wall, and the unslotted drive bit grabbed firmly without any cam-out. The zinc coating seems decent for indoor use, and all 100 screws came straight without any bent ones in the box.
