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.
They bend a little bit too easy, so make sure you take care when nailing them in. It is critical to pre-drill a hole then hammer them straight on firmly.
We replace the cheap plastic pads from our west elm dining chairs with these nail-in felted pads and it was the best decision ever. No more scratched on the floor. Easy to clean with mild household cleaner.
Save yourself a headache and go with a different product. Useless piece of *. Hard to install.
Hammering too much or too hard causes felt to flatten. The nail is not heavy duty and not fastened well to the pad. Seems as though the nail pokes through the foam when there is someone weighing down the chair.
A good product spoilt by it’s small size. About the size of a thumb tack.
