This maybe a silly question as we don't use these type of clamps in NZ as much. I understand the rating of the clamp but is there a rating on the bolt or this all together? Why I ask is apart from the teeth it seems the tightness of the bolt is what stops the light from falling off the bar if the centre of gravity does not run directly through the center of the clamp.Here we use Hook clamps the same as Europe.These have the advantage in that the light will stay on the bar even if the bolt comes loose unless you have the light over the bar. But these are good in schools etc because the bolt normally has a handle not a bolt head. Also the clamp holds to the lights yoke using a bolt with a wing nut . So as long as someone hasn't come along with a spanner and overtightened the wing nut you don't need tools to hang these lights.Getting back to my inital question, if a bolt is lost out of a C clamp and replaced with one from the hardware store does this derate the C clamp loading capibilty?I think the last time I used a C clamp was on some old Colortran Fresnels.
