So I'm trying to attach some 2x4s to my ceiling so I can hang my bikes (2 total). I was going to use some wall anchors rated for 100+lbs, four per 2x4, but I drilled right into the metal frame/studs. What kind of screws do I use to attach objects to that? I figure if I'm right on the metal frame (same as hanging drywall, right?) It should be strong enough to hang one bike per board.
I'd move the boards further inward but I'm kind of space constrained...
Something like this?

You may also be able to use construction or sheet metal screws, I've never tried attaching anything to a steel stud.

I do metal stud framing every day.
Unfortunately, the answer isn't straight forward. It depends on the gauge of the material.
Light gauge non-load bearing studs up to about 20 gauge use sharp point metal screws. Like drywall screws with points and fine thread.
Heavier gauge materials require drill point screws.
And red iron requires even heavier drill point hex drive screws that self-tap (you can't buy these at Lowe's)
You can't use coarse thread screws- they are for wood.
You said ceiling framing... are those floor trusses for living or storage above? Then they are heavy gauge studs- drill points.
It's possible you are hitting red iron, but unlikely.
I would buy a small box of drill point drywall screws, and another of sharp point fine thread screws. Try the drill points first. 2 1/2" long. 2 screws per joist.
If it's light gauge framing, the drill points will skate off the framing. Then switch to the sharp point screws.
Thanks guys! This is pretty close to what I'm finding other places. Most recommendations/knowledge is a mix of self-tapping zinc screws or toggle bolts.
In reply to chknhwk :
Not toggle bolts. Those will attach to the drywall, but you won't have success putting them through metal.
In reply to SVreX :
Are these considered drill point screws? The metal seems pretty heavy duty but doesn't look like iron. It's white and honestly almost looks like it's coated in something.
In reply to chknhwk :
Nope. Those have sharp points, and coarse threads. They are designed to go into wood.
Drill point screws have tips that look like the end of a twist drill.
