Great replacement! On a cold morning, all 4 wheels of my SnapOn rocking chair fell apart. After more than 20 years I can understand that. I wouldn't pay for any other place! These are the perfect replacements! Judging by all the other reviews, the old ones will be your biggest problem. Lots of WD40 and a heavy vise will help. You can round out the holes with a sharp 3/8 bit. The new insert nuts are slightly larger. Good product! Fast delivery!
