Help! ! cvt cover screw broken

So I did a clutch kit install on my 2015 outlander L, and when i Re intalled the cvt cover (following the torque specs in the service manual) low and behold , i snapped the screw. ..any one know if i can get a generic screw in stainless that i can use in place of it. ..btw i live in Canada and shipping one oem screw to Canada would cost me almost thirty bucks! Can you use a regular M6 X 30.5 screw and just add a rubber washer to it, or does it have to be the oem screw to function correctly? Also, if you can, where( in Canada)can i order it from or buy it? Thanks in advance
