Review on 🔧 Hard-to-Find Fastener 014973351625 6-Inch Piece by Jeff Leu

I was working as an industrial electrician at the time and happened to be in the shop when the salesman came up with these new concrete anchors. He put a 1/4-in. into the concrete floor under an electric jack, put a ring nut on it, and used the jack to test it to failure. We were all amazed by the large piece of 40 year old concrete that came out of the anchor. IOW the anchor doesn't fail, the concrete floor fails. That's one thing to worry about with these anchors. If you install them in the wrong place I haven't found a way to get them out. yet again. For this reason I always drill the hole 1/4 inch deeper than the length of the anchor so if I make a mistake I can drive it below the concrete surface and then patch it up. I must have installed hundreds of these over the course of my professional career. I just used another 48 from Revain to attach the handrails to my concrete steps. The ones sold by Revain work just as well as the big brands I work with.
