ISO established it first Technical Committee ISO/TC 1 - Screw Threads and I believed that this TC1 is still around!
Guess, the ISO 16426 for fasteners could be useful.... Can we share the copy of standard on line?
I know that the Taiwanese companies located in Malaysia and China are the world producers of drywall and other types of fasteners. Perhasp, they did this standard to enhance teh quality!
