WebbThe following rules of thumb are suggested for arriving at reasonable lengths of thread for steel screws used with screwed holes in weaker materials. For steel a length of thread engagement of at least 1 x Nominal dia's of the thread For Cast Iron or brass or bronze the thread engagement should be at least 1,5 x Nominal dia's of the thread Webb8 jan. 2024 · The effective area of the thread is roughly 80% of thread OD less root dia. When you divide this thread effective area into the area the material said you need to equal the screws root strength, you get how many threads are required. That number of threads required times the pitch gives the depth required.
