It needs to be as tight as necessary to keep the cable from slipping. This is especially important if you're talking about a brake cable.

if the bolt never seems to tighten up to proper torque and just turns and turns, check to see if the threads are stripped. if so, replace the bolt. torque depends on the type of bolt (brake, front derailleur, rear derailleur.?) and what the manufacturer recommends for the torque range.

Need some more info. Which anchor bolt and what do you mean by loose? If you tighten it and the cable still slips you may not be putting the cable in the right position or the piece that presses on the cable may not be positioned properly. Please explain further and either provide closeup pic or look for an image online of derailleurs/brakes with cable attached to see proper installation.

As far as how much to tighten, I know very few people have access to torque wrenches, esp for that small a bolt, so I'll give another option. The rule I have always taught is to tighten until you feel a quick increase in tension. That is generally a good place to stop. Much easier to tweak a little after that point than to deal with a sheared bolt or stripped threads.

My first thought, given the amount of information you provided, was to recommend you tighten it or your boat will probably float away. Would you care to be a bit more explicit or is this just a troll?

There's a set torque for any fastener that you don't want to go past. Especially if it's a small short bolt in aluminium threads such as found on brake arms. So no, you do NOT want to just tighten it as much as you can or whatever it is will strip the threads. A brake cable should be easy to anchor correctly with just two fingers on the allen wrench.

Or as mentioned above if it never locks down properley then it may already be stripped. Or maybe the cable cut a deep notch from slipping in the past and now the screw and clamping plate can't put enough pressure on the cable before it bottoms against the sides of the groove. You'll need to take a good squint at the situation to see which applies to your case.

And yeah, we aren't paying for the bandwidth so posting more information would really help. Unless all you want is a similarly short and equally confusing answer.
