Great high quality expansion plug but the title suggests you'll receive 10 pieces yet I only received a single one.

I received a pack of 10, so that's the good part. The bad part is that they are too large, as someone else stated in their review.These do not fit into a 1 5/8" opening. Since I needed to replace at least one on my motor, I did grind and sanded the outside of one plug and installed it.. Still way too tight so frost will not push it out if it should happen...Probably use the rest for target practice...
