Spring Nuts

[Bluegrass Boy]

You mentioned block wall, make sure to drill into the brace section of the block, or if you had to hit the hollow spot, then we used the hollow wall anchors. I have seen toggle bolts used, but would not recommend 1/4 in. The toggle wings are not very strong and you would have to upsize.
Here’s an example of hollow wall anchors we used often, with an anchor setting tool.

If the strut is sitting on the floor then 4 or 5-1/4" toggle bolts are fine if you hit the hollow portion of the block. The strut will only be holding the "tip" weight with most of the weight sitting on the floor. No different than using strut to mount a panel to drywall.

However, I would like to make an alternate recommendation, because they stay in place SO much better when you're trying to thread in a bolt while holding up the cabinet: Cone nuts:

aggghh I hate these. They always seem to push through right when I need them to stay the most.

I know what you mean, but, in my experience, the spring nuts move much more easily.

For sure, the nylon nuts stay in place a whole lot better. And they don't push away from you as you're trying to get your boat started.

And if you need to slide them some to get you're not lined up with your whole better, they don't tip over and pop out.

I never use spring nuts if I can help it

No, it can't be. That's against the rules.

How do spring nuts work??

there is a thread just shut down 45 minutes ago regarding inspectors, surface mounted boxes and clamps
what’s the difference?

SSDriver pro-tip of the day.

For mounting heavy drives or panels with external holes I will use a 2" bolt threaded through the spring nut backwards to create a stud. I then un-thread the bolt until the head touches the back of the strut. You now have a stud that can't be pushed back and will not move when setting a heavy panel. They sell stud springs nuts, but they still move, this does not. Also no need to hold the back of the bolt as it is unthreaded and touching the back of the strut and is now wedged between the strut and the spring nut (it will not spin when you thread on a standard nut).

Staying on topic....how do you guy support panel recessed in drywall with metal stud. Say a 225A 42ckt size panel.


Ahhhh just saw infinitys post about toggle bolts for drywall. Wouldn't they rip through?

Sleeve anchors are superior for cinder block walls, and I much prefer the CONE STYLE channel nuts to the spring style ones.
Spring nuts do not work well with slotted unistrut.

If it's recessed we just screw it to the studs either with self-drilling screws or 1/4" nuts and bolts. You missed the part about mounting strut to the drywall where the strut sits on the floor.

Shut down thread was a guy who was not an EC and was working on his own house. This thread's OP is an EC who is active here and was checking how to do something for a job.

 

[LarryFine]

I would, and have, screwed sections of top/bottom plate track over the open side of steel studs to provide a fastening surface.
