Man, you guys got all bent out of shape here...
The shims in his posted picture are commonly used to shim 2 metal parts, very often on the steering knuckle mounts on cars. They're also used on hundreds of other bolted applications. They are "U" shaped so they can be slipped over a loosely assembled bolt.
arorra500 simply used a picture of a shim he likely found on the Intardnet. Look at the properties of the pic. It's hosted by:

They make all kinds of bearings, seals, mounts, and related products. All he said was that he used one of those type of materials to shim a lock. It's not that hard to believe. I've got a couple Schlage rekeyable padlocks that use sprung latches instead of a cam-and-ball, and the Oakland Ice Center paid almost $50 a piece for them so they could have the entire facility on a master key system. Expensive doesn't always equate to quality. If in doubt, check out a new Mercedes.
