This is a good read on bolt and nut strength.

Re: This is a good read on bolt and nut strength.
This really is great -- I didn't realize #2 in the thread strength fundamental... but it make sense!
JOHn
Thread Strength
Two fundamentals must be considered when designing a threaded connection.
1. Ensure that the threaded fasteners were manufactured to a current ASTM, ANSI, DIN, ISO or
other recognized standard.
2. Ensure that the design promotes bolts to break in tension prior to the female and/or male
threads stripping. A broken bolt is an obvious failure. However, when the threads strip prior to the bolt breaking, the failure may go unnoticed until after the fastener is put in service.

Re: This is a good read on bolt and nut strength.
Glad you liked it. Also interesting was the thread strength distribution and the cautions about mixing dissimilar metallurgy, i.e. no grade 8 bolts thread to mild steel.
