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!

If it's an "I" beam you may be able to clamp it to on of the flanges. If not you are looking at drilling a hole & using an eye bolt. Support beams are heavy gauge steel & you chances of screwing into it without drilling are pretty remote.

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.

They make clamps designed to hold piping to that kind of beam in industrial buildings. Take a measure of the flat width, and go to a plumbing store. Tell them what you've got in mind. The clamp method might work out. Otherwise Master U covered drilling quite completely. I'll just add, definitely use eye protection.

Master U said it all.
