Did I buy a shitty bed frame? These bolts just slide in and out of the frame, I can't tighten them and the bed feels like it's gonna fall apart at any minute.
You cant tighten them as in you can't force them into the material any more than you have, or that they just pull out immediately?
If A: Try harder or go buy a drill or impact driver or something and force that bitch in.
If B: Take the bolt out, goto the hardware store, and get one slightly larger.
what is on the other end of the bolt? is it threaded - if so it sounds like you are missing the threaded nut that the bolt would thread into. often these type of cheaper furniture there is a nut that slips into a slot then the bolt treads into it holding the two pieces together.
>Get screws slightly bigger than the bolt
might work temporarily but chances are this is made of crap press board - larger screws in place of the original bolt (and nut) would most likely rip the shit out of the press board making a bad situation worse.
Holy shit are we memeing or are we all actually this retarded? You're missing the other end of your bed bolt OP, have a look at what you've got there, does it have a thread on the inside of the sleeve? If so then just go get some replacements, if you have the threaded end then you need some cams. Home depot will probably sell all this.
