Having ridden my P7 about 4 times the drop out bolts are getting chewed up by my cheap tools and quack handedness when adjusting the SS chain tension. I'd like to replace them with Ti but I'm not sure what size they are? I think they're about 4mm but how does that translate into "M" is it M4? and is this the right size? I'd measure them my self but I'm not with the bike at the moment.

Sorry for the stupidly lazy question but you guys always seem to know answers faster than I can find them under my own steam!
