24pcs Chair Leg Floor Protectors... vs Screw-On Felt Pads by X-Protecto...

Pre-drill each leg with a 1/8 bit, then screw them on. It takes the longest to apply due to pre-drilling required, but worth the effort. Drill a pilot hole then screw in.

Unless you tap it perfect every time (big or small taps) they bend and are useless. Attempted to replace similar product with previous nail holes and still terrible. Scratches your floor when the felt wears off--which happens pretty quickly.
