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?

    Just consider wheel bolts or nuts on a car wheel. The bolts on my vehicle have to tolerate great temperature changes and vibration. They do not come loose, even without locking nuts.

    Wheel nuts have quite a reputation for coming loose - that's why these days they're multiply redundant (there are many on each wheel so one or even two can fail without risking the wheel coming off), torqued very carefully when altered and on larger vehicles have movement indicators added (those little plastic arrows).
