The magic words to search for are "socket head cap screws". Once I figured that out things got a lot easier. I bought mine online from amazon.ca.

 

I believe most ST80 rings these days are M6x1mm, which AFAIK is the most common M6 thread (so if it just says M6 you're probably OK). I bought screws with 20mm of thread which was OK for my Vixen plate but turned out to be a bit too long for my Losmandy plate - recommend something like 16mm instead.

HI...I can't tell from profile where you live, but try to find an old-fashioned hardware store (Ace, etc) that has bins of bolts, nuts, screws, metric, etc. We have one here in Fairbanks, and I am there all the time matching up bolts and attachment devices for my astro projects.  They should have socket head cap bolts for you, in a range of sizes and threading. 

 

Good luck with your project!

 

Mike

Oh good. Mike's recommendation about ACE is a great one as well... there aren't any around here that I know of but when I'm travelling in the US I usually stop into one... I invariably leave some important fastener at home and they are have a really good selection.

 

You might want to confirm the thread in your scope rings with a 5 cent bolt from local store before buying a bunch of the cap screws.

I once read a history of the hardware store.....yes, such a book exists. (or existed)

 

Ace, Sentry, and you r local mom and pop stay in business by providing things the big hardware stores don't, or at least not conveniently. Take whatever need a fastener for to them, and they will fit you out.

 

In the case of Astro equipment, you can either get plain or stainless. Get stainless......both work fine, and in practice, you may never note a difference. But Stainless look nicer. Cost more, but at the price of nuts and bolts it is insignificant.
