Question: How does the knob get attached to the lid.
Document: Disappointed to find that these replacement knobs have a smaller screw hole than the old knob connectors can accommodate. Will have to either drill larger holes in the new knobs or grind down connectors on the lids to get them to fit. Lots of work, and not what I'd envisioned after reading the description of the items!
Very pleased, good quality. We recommend. Other cheaper ones are advertised but we recommend spend the money and get a better product.
Exact replacement for the original pot lids. The bakelite knobs don not do well in the oven and get porous and were ready to crumble. Now the pots are like new.
These fail after a while, but there the only thing you can get to replace the original knobs. Not the same material as the original and the threaded insert fails after medium use. This is my second purchase in 5 years.
Never thought I'd find these. I mean, I really enjoy cooking with my RevereWare - but, time marches on... things get old... things get broke. Then (cue the Superman music) ta-da, not only did I find THIS replacement part, but handles, loops, copper cleaner - the whole sha-bang. 'Mazin'
The replacement knob did the job and was very economical. Now my original Revere Ware lid looks like new again.
The knob fits perfectly to my Paul Revere lid that is more than 10 years old. I am quite pleased to be able to find a replacement so easily.
This replaced my 6 Qt Revere lid knob. Look almost the same. Stays cool to touch, is dishwasher and heat dry safe for 14 months so far. A+
These screwed right on to my old revere ware pots. Beware though, I broke off the lid trying to remove the old knob, so now there's no male part to screw on to.
Perfect replacement part for a well-used lid. I have been searching thrift stores for a used lid and had never considered the possibility of simply replacing the knob. Thanks for solving my problem do succinctly.
Answer: In my case, the small screw stud that was originally attached (welded?) to the lid was still intact.  I simply screwed the replacement knob onto this screw.  On the original knob, the screw threads inside of the knob were worn out.  If your lid doesn't have the stud, a small hole will have to be drilled and a screw inserted from the inside of the lid for the knob to attach to.  I don't remember if any screws came with the knobs I ordered.
