I searched back through the archives looking for lug bolts for alloy wheels. The $25-ish chrome ones on EBay sound like they are the wrong shape on the ball surface. A year ago Headrage mentioned these (select 35 mm) :

Headrage, have you been happy with them ? Anybody else ? They're like 1/4 the price of the known good bolts, but don't have the fancy polish and chrome . Sounds like what I'm looking for, but I don't wanna lose a wheel....
