Defective hardware (bolts)

Harrumpf. Even at 1,000 pieces/hour, that's still a half-hour's worth of 100% bad parts. It's pretty poor manufacturing to not notice that.

Indeed it is, however a majority of consumers will not pay more for increased inspection intervals or very expensive in-process inspection technology.

The remedy is to just take the bad ones back and give the consumer 500 more no questions asked. Exactly how much money per screw did they cost?
 
Those bolts probably came from China and there is no quality control over there. There are no junk yards in China, they send all of it here!
I refuse to buy China made and will go out of my way and pay more for American made products.

Individually they are 0.35 euro each, when buying in bulk on a box price is 0,15 euro a piece, they are not made in china, i think the box said made in Belgium.
 
It happened again, but this time on zinc plated M6x25mm steel bolts, different store different manufacturer, the same problem, the bolts had a part of them pulling away, but this time i check them in the store and asked for a different box, they exchanged them right there but i did not take a picture to share, talking about no QC.
 
This thread is a reminder for me to do QC on everything I buy from anywhere. It is too easy to believe that things are the way they should be but in reality they are not ALWAYS especially when humans with smart phones are involved. Thanks for sharing GoceKU
 
If the bolts wernt made in China,Ill bet the stainless coil was............recent case I witnessed a EWP was rebuilt for 10 yr inspection,all new 11.8 bolts in the turntable mount to frame...........bolts all tensioned by a hydraulic unit............worked a few hours ,when the machine was moved ,painters noticed a lot of new nuts and bits on the ground...........around 2/3 of the bolts had cracked around the thread in a spiral as they were tensioned,and broken off completely when put to work.....all the bolts were OEM supplied certified.......but the machine was Chinese,so the bolts were too.
