That's a good trick, Van !
Remember too that not just any bar will fit these ! you need the correct size Cinelli bar, 26.4mm diameter. If you use a bar that is 25.4 or 26.0 diameter, both of which are common bar diameters, you won't be able to get it tight enough and may crack the clamp.
If you have to resort to "carbon paste" or other band-aids to keep the bar from slipping, something is not right.
Lastly - allen keys do get worn out and can damage fasteners. Treat yourself to a new set of allen wrenches (the Wera allens are awesome) or touch the business end to a bench grinder every year or so.
