The screws fell out of the bottom of my MX-300 and I need to find some. It's the screws that hold the MX-300 shoe adapter into the main part of the MX-300. 4 of them. Maybe metric size I think. 2x56 are just a bit big.

I tried chasing them down on Canon's site but whoa, not real easy.

Thanks

Bolt Depot had some real esoteric screws I needed awhile ago.

I bought an MA-300 adapter off someone from eBay, and it was missing those 4 screws! So I called Canon, talked to a representative and got some shipped to my house. It cost like $8. FYI, when I got them and put them in, the box stayed loose/wobbly in conjunction with the shoe part.. It lead me to believe that something additional was needed, like little washers or something, to make the connection tight. I never found the answer because at that point I sent the MA-300 back and got a refund.

But yeah, call Canon.

Thanks everyone.

I ordered some screws from Micro Fasteners (http://www.microfasteners.com). $1.60 for 50 each of part # FMSP2012, 2mm x 12mm Flat Head Machine Screws. $4.00 for shipping instead of the usual gouging.

I tried the Canon route and it was a pain to get help.

Never saw the screws getting loose, just one day the part fell loose and no screws. I have 2 screws in there now but they are too short and barely hold and I can't use the adapter. It seems to be just the screw goes into a metal plate that is tapped inside, not sure if anything else is missing like mentioned above. I'll follow up once I get the screws and install them.

If anyone needs some screws I'll have a bunch left over.

2mm x 12mm Flat Head Machine Screws did the trick. They did thread a bit hard so I'm not sure if they are the right thread count screw. I just used a good #0 Phillips head screwdriver. No other parts were needed.
