Does anyone have any idea what the thread is for the knob screws on a pair of Kluson cam-style D tuners? I have a pair that I bought somewhere a long time ago thinking that I just needed a pair of screws to hold them together. Now that I have a banjo to put them on, I can't find any screws that small. If I knew the thread gauge, I might have a decent head start trying to find screws.
Our ACE Hardware store has thread counting equipment in their screw and bolt section.
Even if you don't have a screw to test and match, Ace is still the place.
If these Klusons are like other tuners, you might be looking for a #4. Pretty sure that's what I bought about 10 years ago when I needed replacement. Don't remember knowing the thread. But it didn't take much testing of screws to find the right one.
Another vote for ACE Hardware. I’ve been buying banjo hardware from them for over two decades. I bring the parts or the banjo with me, to get it right.
Off-topic from the hardware being sought, but in a marine hardware section at Home Depot I found chrome nuts and washers that (while bigger outside than typically used on banjos) were functional replacements for use on coordinator rods.
I can't tell you the exact size, but I can say I also have those Klusons and was in the same conundrum when I was looking for a thread chaser for them. I went to my local Ace hardware which has template guides, male and female, where you can match the right size bolt or nut you need. I would perhaps suggest your local hardware store and if nothing else they may be able to find your size by matching it with a nut or bolt.
