I'm putting up a 3 gang dryer frame, middle & each side 15hp blower, into concrete. How'd you guys suggest I bolt it into concrete & bolts for 3 piece square aluminum frame?

1/2 inch drive in anchors. If there is floor heat locate that first.

I don't have floor heat, in OKlahoma or Texas. How much are those drive-in anchors, & where would you find them?

Go to Confast.com and get stainless whatever you do so they don't rust. I know when I order I get it in like 2 days. I don't even get concrete bolts from home depot or lowes anymore the quality isn't there for me

1/2" Stainless Steel Concrete Wedge Anchors, sleeve anchors can also be used but wedge is preferred.

Be sure to use Stainless everything. You'll be glad later......
Bolt frame together with 3/8" (length appropriate) stainless steel bolts, SS washers, and SS Nyloc nuts (Nyloc nuts resist vibration better than lock washers in the long run, 304 SS OK).
Set / anchor frame to concrete using 1/2" x 4 1/2" (or so) stainless steel wedge anchors (not sleeve anchors, which are made for block). Sink anchors at least 2 1/2" -3" into concrete (with no deice tubing present) and set.
Use anti-sieze compound on all threads.

I just added some new dryers to a couple of my automatics. They used 1/2 inch wedge bits like the one pictured. I have also used 1/2 inch wedge bolts in the past with good luck. One tip the installer mentioned ( He has been doing this 40 years) was that if you are using wedge bits drill the hole all the way through the concrete. In a few years if you have to take things out you can simply drive the bit down and not have to cut it off with a grinder. Since you put the bolt on the wedge bit prior to driving them in the concrete you do not have to worry about them going in too far. Wedge bolts have a higher strength rating but most people use the wedge bits.
