Here's How That Shitty Hardware Is Made....

 

 You know damn well stuff like this is repackaged as NIST compliant in this country.

  1. You know that Boeing's CEO is smiling: an other bonus for lowering the budget of the safety department.

  2. I do QC. And no matter how hard I try to get USA made hardware, purchasing always sends Chinese or Indian hardware.
    I sweat bullets every time I pull final torque on a fastener.
    10% failure rate. Always in the worst place to replace.
    I do reject it in critical applications. But I can’t see the cost benefit of cheap materials. Labor is always the highest expense in any industry. Yet PM’s never factor the cost of disassembly/reassembly to replace trash hardware into the costs.

    1. We go through a lot of b7m studs every year, never seen one fail. Our supplier makes them in NA.
      We use special studs on steam applications. We got a box in from a different vendor. Could not get gasket compression with them as they stretched way more than actual b7m ones are allowed to. Sent the box back as reject, india made

      We see a lot of failures on bonnet bolts on valves, again they stretch over time loosing compression on the gasket causing a leak. Even made in US valves often have foreign discount bonnet bolts.

    2. @ Anon 8:23AM If fasteners are specified by engineering, Purchasing has no wiggle room in what they purchase. Bolts and most other fastening hardware come in grades where the material, tensile strength and hardness etc are specified like on this chart:

      https://www.aftfasteners.com/grades-of-bolts-bolt-grade-markings-bolt-strength-chart/

      There are also similar charts for screws, nuts and washers. Purchase orders should be written with the exact specification for the material being purchased with grade, material, hardness, tensile strength etc and the supplier should be certifying that the particular product meets those specs by supplying their test results on the lot supplied.

  3. God only knows what's in that steel.

    1. In India, of it'll melt, it goes in the steel.
      About the only Indian metal things I somewhat don't fear are cast metal manhole covers.
      Kinda hard to screw up a manhole cover.

  6. Sure,the bolts may not be the best but I respect these folks for working/trying to make a buck in some pretty dangerous(for fingers especially)conditions.

  7. This is one clue as to why buildings fail during an earthquake in that part of the world along with really bad engineers.

    1. The safety shoes and eye protection were just as good. Sandals and blinking.

  9. I can still hear bill clinton intone, as the chyneese were given the last steps to favored nation status: "...and good, far the...Ammurr-uh-cun...people (big smile)."
    I cannot explain the treachery and treason that took place during that time.

  10. Will they be promoted to “Robot Polishers” is my question?

  11. Well they were doing some QC with a tape measure. Love the safety sandals. The little voices were probably apprentices in training. /S

  12. Well....that explains the last box of screws I got at Home Depot. 6 out of 10 had the heads break off while I was installing them in plywood. Made in Red China.

  13. Back in the late 70's, the farm.supply chain I worked for imported bolts and nuts from India. One shipment of 50lb boxes were nothing but gravel and dirt.

  14. Boeing acquisition folks need to see this

  15. China crap is NOT DFAR compliant. I don't believe India is either. You get caught playing with certifications for hardware or material with the DLA or DCMA look out. The penalties are pretty stiff. There was a distributor is SoCal a couple years ago that got caught falsifying the country of origin and test reports for a shit load of 6al-4v. They are still in jail.

  16. Well, now I know why the threads aren't even anymore!
