K&M Thumbwheel Alu BK

Kind of.

I mean, it's a lock nut. It works.

However, no matter how carefully one screws them down onto the threaded tip of a stand or boom arm, before packing the stands into their flight cases, some of them will always magically work loose and fall off in transit even if the stands are stored vertically in the cases and cases transported upright! Magic, right?

Or maybe just physics but that doesn't make it less irritating when the stand you just carried half way across the venue is missing its lock nut and the upper tube has dropped through into the base!

Not only that but where do they go? A few drop into the case but most vanish without trace! They're probably swarming with the lost socks from the washing machine, Sharpies left unattended at gigs and XLR adaptors that never reappear after being "lent" to the stage crew!

So it's good that K&M sell them separately.
