Solid product

Would Recommend

I bought this along with several other of this Steeltek line to build an 87in long console table for behind my couch. These were so easy to use and line up, and the finish seems really durable so far. We will see if they need tightening over time but for now very happy with them.

The Tiny Black Pancake That Carries My Dreams

Would Recommend

Bought this 3/4” SteelTek black steel flange to use as the feet for my amp shelf, and let me tell you: this little chunk of metal showed up ready to support both my gear and my questionable engineering confidence. At first glance, it’s just a flange. A humble, round, black piece of steel with holes in it. But in practice? This thing is the unsung hero of the whole build. My amps are up there looking majestic, and these flanges are down below doing the blue-collar work without asking for praise....

Fantastic clothing rack base

Would Recommend

I decided to use this along with some additional pieces to build an industrial style clothing rack. This piece is fits perfect; with a couple bolts to the celing joist and a couple floor ancor bolts, i can literally do pull-ups on my clothes rack if i wanted.

Great Product, Easy to use.

Would Recommend

Great for securing my 3d filament rack to the wall. When used with Toggler sheetrock bolts, this holds about 20 rolls along a 72" length.

What size are the set screws please?

What size screws do you use with these? I’m having a hard time finding one with a diameter big enough.

I want to use 3/8 " fittings and pipes. Descriptions on these items states that they are meant to be used with 3/4" fittings. Is this a problem?

What are the dimensions of the base where is is secured ?
