Hello,
I hope someone can be so kind as to help me with a query.
I have recently checked a batch of products from a new Chinese manufacturer. The first crate of goods passed all of my tests so I approved it and moved it out of quarantine. We also had it tensile tested for strength - it passed.
So it was sent to the customer.
But today I found significant defects but none that can kill people! I was coming to the end of the final random sample and I can see that they have machined out the initial female thread recess with a much, much bigger diameter drill than they should.
Resulting in the label B being cut like it is.
Now I don't know if I have found 1/5000 like this but this can be very serious for us if one was to be like this. I need to do a full product recall and 100% inspection.
The threads in question are Female M16, M20,M24,M30
I am extremely worried about this and I do not know how to find out the minimum/maximum dimension this should be for British standards. I hope people understand what I'm asking?
