One guy runs a factory that makes 400k screws per day
 

It looks like he's making the screws in a building that could be a small storefront or home.

You've gotta love the Japanese!

He's not screwing around. I bet he does enjoy drinking very much.

I love a good screw

Think of what a miracle of economies of scale a screw represents. You want a precise micromachined component with a swept incline plane, made of high strength alloy, with a blind hexagon hole in one side?

Sure that will be 20$ for a box of 100.

Yeah, when I posted I hadn't gotten to the interview part at the end. I love that bit:
"Do you have any hobbies?"
"Jogging once per week. I enjoy drinking very much when I get back home."

Makes you wonder if the drinking is post jog or just nightly when he gets home from work.
Yep, amazing, and possibly more so that this guy is doing it by himself like that.

I want to see the boxing operation...

I think he may be screwing up his hearing.

I knew a guy that started a company that made all the little screws that were used in Bausch and Lomb (Ray Ban) glasses right here in town. He mad many millions of dollars doing this. Probably all MIC now.

I too love a good screw. RC cars are a hobby and soft screws can really ruin your year. I delight when I receive a good quality hard screw that doesn’t strip or snap in half. Pretty sure the best ones I get are from Japan. The simple things….

Those screws should be U.S. made, think of all the jobs they would create.

It does matter. SmileWavy

The year is 2009. NASA is launching the Orbiting Carbon Observatory (OCO), a satellite engineered to map carbon dioxide levels in Earth's atmosphere. The mission is mounted on the Taurus XL rocket, and expectations are high.

But moments after launch, the rocket's payload fairing, which protects the satellite during ascent, does not separate as planned. The extra weight prevents the rocket from achieving orbit, and the satellite crashes into the ocean near Antarctica.

Two years later, in 2011, history cruelly repeats itself. Another Taurus XL rocket, this time carrying NASA's Glory satellite, fails in exactly the same way. The fairing doesn't separate. The rocket doesn't make it to orbit. The mission is lost.

After years of investigation, NASA identified the cause: counterfeit high-strength fasteners that could not withstand the stresses of launch were used in the fairing separation system, causing it to malfunction.

The cost of these two failures? Over $700 million, not including the years of scientific research and effort lost with each disaster.

Best little screwshack in Japan?

I watched it twice

I'm totally gonna show it to my girlfriend. Should get to about :30

I'm not sure this is strange - but I can SMELL that room while watching the video!

That's exactly what I was thinking while watching.

Yep, that smell. In my younger years, growing up in Rockford, IL. the screw capital of the world, I had occasion to work in the fastener industry running machines. I smelled like that oil every day.

First gig was in a plant with equipment about like his making screws and rivets. Dirty, oily and hot place. Second and third gigs were with an aerospace fastener mfr. Clean, air conditioned, better equipment and fun materials - Waspaloy, 17-4, Hastelloy, Inconel and Titanium. It was a good gig and they had plans for me. Left to pursue school efforts. Same oil smell and I have a shop apron hanging in the garage that still has the faint odor of the oils.eaxes used, even 50+ years later.

Many years ago my sister worked as an accountant for a ball bearing company in Illinois. I always wondered how such precise little round steel objects were made. I guess YouTube would tell me...
