Crucial-application fasteners are discussed.

 

That's a really good publication. I use t read it all the time when I sold hardware.

 

Man they need to read an engineering text. Their theory is right, but the words are all wrong. It's not ductility, it's elasticity. There's no mention of yield strength, or ultimate tensile strength, or anything like that.

Here's some good stuff. http://inventor.grantadesign.com/en/...20strength.htm
