When you are on the mission "alien soil" on the planet "Sarathos" (you must be on challenge mode) there will be a part where there are two hacker orbs. Hack only ONE of the orbs and the other of the orbs only partially. Once you have done this, there should be enemies popping out of the ground to stop you. Once you have done this, pull out that wrench of yours and start wacking like crazy. (It is best not to use weapons and to be on "couch potato" mode.) Once you hit the x20 on your meter, you should start to rack in the bolts like crazy. Remember this is best for the first time you enter challenge mode for there is no use to make millions of bolts after you have bought all the weapon upgrades.

Easy money and Level 99 weapons:
Get to the point where you unlock "Endzone" in challenge mode. Repeating this challenge can reward 3-5 million bolts per try, as well as leveling up your weapons quickly. You'll want the shock mod equipped, but also try using mini-turrets and the holoshield launcher. Just remember to equip the weapon you want to upgrade after setting up your sheilds and turrets.
Lots of bolts:
While on planet koros, smash everything as you go through the board. when done, go back to your ship. save your game and jump into the water to die. when you come back you will be able to run through the board with no enemies to smash everything and collect bolts. if you do it enough over and over, you start getting more bolts for everything you break. eventually you will get about 75,000 bolts everytime you go through the board. Do it as many times as you like.
