Greater than one weekThese worked perfectly in my dripping Kohler whirlpool tub faucet. The biggest challenge was figuring out which size to buy and then removing the old one. Over the course of about a week, I tried spraying the old one with WD40 and then PB Blaster every day or two. Neither worked well enough to loosen the bolt. A friend had a much larger ratchet than mine which I borrowed and it did the trick — probably because I could get a lot more leverage on the longer handle. Next time I would try even insterting the end of my smaller ratchet into a pipe to lengthen it. In this photo you can see my much smaller ratchet next to the granddaddy sized one that I borrowed that did the trick.
