B.S. 951 Bonding Clamp.

Zoomup
Good morning,

                           I have often wondered at just what is the purpose of the locking nut on the main fixing screw on a B.S. 951 bonding clamp. On static non vibrating pipes I can hardly imagine the screw becoming loose. So, is the locking nut superfluous? Or is it perhaps to allow correct orientation of the razor blade sharp warning label?

    Oh yes that F******* label, for something so flimsy it can deal out some damage ? however I visited a house, back in the days of the 15th Edition where we would bond the garden gate, that the owner, I quote, " an accomplished handyman" had installed the new kitchen but needed a socket for the washing machine checked. The socket as is always the case was buried at the back of the cupboard under the sink so getting to it was fun, however, the fun stopped when i felt a burning pain on my arm, this turned out to be a fairly impressive cut caused by the strap on the bonding clamp that said "accomplished Handyman" had fitted and then cut off the extra tail leaving basically a bacon slicer for the unwary plumber/electrician. A few words of guidance were given and said handyman somewhat sheepishly made the tea and we had a laugh about it, eventually!!

    In reference to the OPs question, I had always assumed it was a simple lock nut purely to prevent the screw from loosening off but also handy for securing the label in position.
