i want to get a punching bag but the only place i can put it on is basement (i also live in aptmt). the only place steady enough to hold a 100lb or more bag is the steel beam (it's the only beams visible anyway), how can i put it on? is it possible for me to screw through the steel?(looks very strong btw). help please!

DO NOT DRILL A STEEL BEAM !!! I cannot believe people suggested that.
There are bemis clamps and all sorts of attachment methods marketed and available thru UNISTRUT. Unistrut manufactures a whole "erector set" (large scale) of pieces and parts for weird construction situations. They, specifically, have clamps for hanging stuff from steel beams.
Look up their catalog on the internet, then call around to Contractors to find the local distributor in your area.

You will need to get a very good drill bit, preferably Titanium Cobalt or Cobalt drill, these need to run very slowly as they are brittle, make sure you have plenty of lubrication on the drill bit, the PTFE lubricants are good for this. Firstly you should use a hardened steel punch to make a small dent in the steel where you need to drill, this will stop the drill bit slipping or 'wandering' - drill a small hole first, then change to the larger drill and use the small hole as a pilot guide. A 1/4" steel bolt will easily hold 100lb (more like 500 lb). You can get some brackets that have the 1/4" hole in them and then they bend out with a slight tongue, this also has a hole in it for attaching whatever the bag is held up with. Unless you use lock-nuts please use 2 nuts one tightened against the other with washers both sides of the beam, under the bolt head one side and the nuts the other, you don't want a nut working loose and the whole lot falling on your head. You could also use lock washers (star or split) to keep the nut secure. Go to Lowe's or Home Depot they have hardware there.

You can drill and tap the beam to receive a machine screw. I would think a 1/4 inch screw would be large enough. A common size that you could find a tap for is 20 threads per inch. Make sure to buy a drill bit that is sized for the tap, and a tool to hold the tap while you cut the threads. A local hardware store should have these items. To tap the hole, drill a hole in the middle of one of the flanges on the I-beam, then start the tap in the hole. Run it in for a couple turns then back it off a little, then run it in for a few more turns, etc., until you have threads all the way through the flange. The steel in the I-beam is soft enough that you should be able to do this without much difficulty.

Well I'm not sure about the sizes. Actually it wasn't even a steel beam, it was wood; 3"x 8". I drilled to holes clean through one higher than the other, diagonal if you look at it from the side and I attached a U bolt to it. Then one that we use on pick-up truck suspensions; leaf spring.
Bolted that thing on and used a chain to hang the bag. been banging on it for so long. its still there till I sold the house.
No welding or nothin. its safe, two nuts actually. If one came off, you still had another.
hope this helps

Use a 7/16 drill bit & 1/4-20 screws that's what is used to hold structural metals in place before welding.

Go to a good hardware store and ask for a bemis clamp (pronounced beemiss), they are very strong, it clamps onto the edge of a steel beam and has a threaded opening to put a bolt into it. They are commonly used for supporting large pipes. There are many sizes to choose from.

Brother Phil is right about all but the size. I did all my work too but, I also owned my own construction company.
You'll need something bigger then a 1/4 inch, I would go 3/8 or a 1/2 this is going to take a lot of abuse, your going to be banging it around quite a bit so....go with the bigger one, you won't be sorry.

visit your local hardwear store. (in canada its any bolt supply house). tell them you need "tek-5's" these will allow you 1200lbs/sq inch. We use the to hang water lines off of steel beams. I have also used them to hang a come-along to hoist a 3500lb boiler.

Blue moon is right. Don't listen to the level two guy. Or just get married. Either works for me.
