content: hello everyone,i am hoping someone here can help me out with the correct name or point me in the right direction. i am looking for a trim pot that will mount flush in a front panel that has a flat head screwdriver adjustment on it like what would be used to zero a gauge. i have been able to find a few similar to that attached image but don't have the room in my case want something more like a regular pot.

content: Take a browse through these pots:http://www.surplussales.com/Potentiometers/PBM-SlotAdj/PBM-SlotAdjIndex.htmlHP also has a bushing that you can mount a pot flush with the front panel, their part #1410-0052. It looks nice and the shaft is recessed, but they want US$6.57 for it from their parts dept. I'm sure someone else makes it and you can find it for cheaper. Pic below (obviously a new one would be nice and shiny.)

content: Hello everyone,I know this is an old thread, but I would like to find something like this for a current project of mine too. The example in the photo would be PERFECT. I need something in the 200k to 300kOhm range.I want to have a gain trimmer accessible from the outside of my project, but since it shouldn't be messed with, a flush or slightly recessed flat head screwdriver adjustment would be perfect. I've been scouring the regular suspects--Digikey, Mouser, RS, Avnet (? I think that's what they call Newark here). Maybe I'm searching with the wrong keywords, but I've been looking for anything related to "panel mount flush mount potentiometer". Is there a better name for this thing?I'm in Europe now, but I actually grew up in Nebraska and I seem to recall my dad taking me to Surplus Sales as a kid!Danke!Jeff

content: Vishay 43P series is available as panel mount. I assume more than that, it’s just one I found in a catalog.Bourns sells panel mount adapters for their trimpots. For example, the H83P is for the 3005/3006 trimmers. Seehttps://www.bourns.com/pdfs/pnl_mnt.pdfAlso, the google keywords are “panel mounttrimmer”. “Potentiometer” without the “trimmer” qualifier will produce non-trimmer pots, i.e. the kind intended for knobs.Avnet is a giant that bought Premier Farnell a few years ago. Newark in USA is Farnell in these parts.

content: Also, how did you not find anything on Digi-Key?! If you browse their trim pot category, the parametric search includes “mounting type”, which lets you choose “panel mount”. They have 15 different models in stock right now.
