The only other thing you'll need is a drill bit made for the pilot hole.

A must have.

Easy on, not so easy off... (Rating: 3.00)
Review : Bought a set of these because the concept looks great. They worked well to align the first two cabinets I installed, but one of the clamps would not come off! It felt like it was cross-threaded and would not open up. After nearly tearing the skin off the palms of my hands, I had to resort to a pipe wrench which opened the clamp at the expense of the threaded shaft, it fractured into two pieces. I would like to buy another set, but probably won't just out of principle.

great clamp but could be improved (Rating: 4.00)
Review : These work well for hanging cabinets and make short work out of alignment. My only critisism is the pin (a rolled piece os steel that holds the two pieces of the clamp together at the screw) repeatedly came out of the hole and allows the clamp to separate. This has happened to both clamps and has been remedied by opening the cylinder with a nail set and redriving it back into the hole. They are always in my tool box and they are used heavily as I am a cabinet maker.If they fix the pin with a threaded hole and pin with a screw thread on the end I would have given it a 5+. I will buy another set in the future.
