There are a lot of drywall anchors out there, but fewer that can hold any kind of substantial weight, and still fewer that can hold heavy loads and are easy to install. FastCap RocLoc anchors can can hold up to 150lbs, are easy to install, and are available in sizes for 1/2″ or 5/8″ drywall. Further, once you no longer need the anchor, it can be easily removed and reused.
To install the anchor, you drill a 1/2″ hole into the drywall and push the anchor into place. The lip on the end prevents the anchor from slipping into the wall.
Before driving in the screw, you want to make sure the anchors are oriented so that the support behind the drywall is vertical and above the hole, because as you pull down on the load, that support resists the torque by pressing against the back of the drywall.
The RocLocs optionally come with self-tapping 1-1/4″ PowerHead screws. FastCap claims the oversized head of the PowerHead screws has 4x the holding power of a regular screw head and eliminates pull-through.
The RocLocs are sized for either 1/2″ or 5/8″ drywall, and you need to pick the right anchor for the thickness of drywall you are using. A 10-pack of either the 1/2″ or 5/8″ will run you $5.95, while a 50 pack will run you $23.95. You can also buy a 10-pack of either size with PowerHead screws for $9.95. FastCap has free shipping for orders over $100.
The 1/2″ RocLocs are black, and can hold up to 150 lbs each, and the 5/8″ ones are green, and can hold up to 200 lbs each.
Also, right now Rockler has a special and is selling a 10 pack of the 1/2″ RocLocs with PowerHead screws for $9.

*I want to note that the first two pictures look like 3D printed prototypes. I think the finish of the actual product is a smooth, cleanly-molded product like the third photo.
