Craig,

Don't assume all Macs are Metric.

I have a few that are not.

They have #4s

All of the later models are Metric. Perhaps some of the early are English.

Craig, I have Stainless Steel 115ksi DIN grade SHCS screw kits available if you need some. The SS is especially handy on hte head cap bolts to eliminate corrosion. Looks good against hte bright blue anodizing, too!
