Does anybody know how to put this (https://www.us.kohler.com/us//productDetail/screw/626005.htm?skuId=589148) set screw into a Stillness Kohler shower handle (https://www.us.kohler.com/us/stillness-rite-temp-valve-trim-with-lever-handle/productDetail/handle-trim/1270658.htm?skuId=1270570&brandId=empty&)? I can't figure out the right hex key to make it work. It seems like a 2.5mm is too big, and a 2mm is too small. Do they make 2.25mm hex keys? Or is it perhaps a proprietary Kohler tool that I'm missing?
The instruction sheet you provided says you need a 3/32" allen wrench.
Both you and @ACK responded within similar time. I’ll look for 3/32. Is that a standard size in an Allen wrench set?– DavidMar 31, 2020 at 0:28
1It is in my small set but not in my larger set. Most home stores will sell them individually. Bring the set screw with you.... AND DON'T LOOSE IT.– JACKMar 31, 2020 at 0:41
sounds great, thanks!– DavidMar 31, 2020 at 1:02
Probably SAE and not metric. Try 3/32"
