yeah, threads get striped in service after few months of working. Material is same as earlier means for BSW and Metric thread as well. Only the change was done in Thread system with same size of threads and bolts replacement.
Dear all
Basically my question is about to hv the understanding about best threading system for casting parts. Will it be BSW or Metric..?
Because same thread area is getting failed in Metric system but not in BSW thread system.
Thanks.
Dear RolMec,
The failure is stripping of internal threads of part which made up of FG200 material casting. After analysis we found that it is due to the lower stripping strength of the casting material. But it has also been observed that the issue is only with metric bolts not the BSW. That is...
@KENAT I have already gone through your provided links, thanks. Pls. see attached image for more clarity of earlier example in tabulated form. Expecting your suggestions for better type of thread system to apply in casting part of machinery having more vibrations as it's a agricultural...
@KENAT yes I hv done the calculations for thread engagement length but not specifically for BSW vs Metric. Also in the calculations the thread engagement length is well within limit. For an example I am having parameters of M12 vs 1/2" bolt. Pls. refer below :
Sr. No Metric Threads...
Hi dear friends and resp. seniors,
My topic is about to have ur valuable suggestions regarding thread type to be used in cast iron parts as per the application.
So basically I am working on design modification of cotton Ginning machine in which all the bolts were given earlier in BSW threads...
