Meech & Herman:
Yes, sharp spikes will go through pennies (often within a matter of a few months).
A friend of mine ended up using the pop out slugs from electrical boxes which were scattered throughout the house following a re-wire (two per spike) and with these the spikes went through the first (top) one within a year's time, but after making a dimple in the second/bottom slug they stopped moving.
He eventually replaced them with little discs purchased @ Audio Advisor (probably the ones mentioned above) as he needed a bunch for a new audio/vidio rack that has eight legs, but the slugs worked fine.
His speakers weight approx. 100 lbs each and the rack/gear @ least 200-300 lbs.
With nice new floors @ stake (even though I'm a cheapskate) I would pop for something designed with the application in mind.
