Hey guys I have a regular sized tobh atty I bought used from my local vape shop l. I use 26 gauge kanthall and when screwed all the way down there is a good enough sized gap to make my 26 not fit. What size screw will work for this bc I'm gonna go out to lowes and see if I can find any. Sorry if this isn't the appropriate place for this and I did a search and couldn't find the size. Thanks!!
