We have these LEMO connectors that are bulkhead mount with fastening nuts that require a proprietary tool. We order the tool and receive the two tools in the image attached. I’m thinking some designer was given the task to design a nut driver and took the description too far.
FYI they are terrible to use
I’m thinking some designer was given the task to design a nut driver and took the description too far.
There would appear to be some semblance … 
Okay, I’ll bite, why do they’re connectors require a proprietary tool for installation? Are the nuts seven-sided or something?
Hmm, what kind of designer do you think designed those? A CAD designer? An engineer? An industrial designer?, a tool designer? Hair designer? Mens bottoms designer? (don’t laugh, that is a real job description!)
Someone who does not assemble the product much I would guess.
PS, I had to google LEMO connector to see what you were talking about. I assume you push these into the hole in the bulkhead with the tool?
The nut is shown threaded onto the connector. It is round with 4 indentations that the nut driver engages.
A little Biomimicry for form factors with color theory for symbolism.
Since others have already gone there…
Reminds me of a great joke:
A pirate walks into a bar. The bartender looks at him and notices that he has a steering wheel sticking out of his pants. Being the curious bloke he is, he asks the pirate, “Do you realize you have a steering wheel sticking out of your pants”?
The pirate responds, “Arrrrrrr, it’s drivin’ me nuts”!
Actually, I thought “rim shot” was spelled Bah Rump Bump… but I digress.
Sooooo … that’s supposed to be a “tamper-proof” nut?
And using blue is a sign of an obviously deranged mind; a tangible oxymoron … I mean,it must be, if you’re going to be p’d off by using a poorly designed tool why else would you use a color that is traditionally used for it’s calming affect? Truly sick.
Couldn’t resist.
Slam Dunk.
Clever reuse of an adult toy mold…
… well theirs the pot calling the kettle black, huh?
