Thnanks for metric measurment😉🙂

[@mobilecommunicationsnetwor5268]

For an Electrical box I see #8 and #10 sizes X 32 required. Could you explain why the inch measurement is not used and numbers are in their place.

I'm trying to figure out what thread I need to fit a 2 inch npt bunghole in a 30 gallon barrel. I need a fitting to fit the bunghole that will have a triclamp end to connect to a triclamp fitting on the end of tigerflex milk tubing

cool!!!

[@damnthiccassboye7138]

is it possible to convert m8 x 1 thread to m8 x1.25 with a tap

[@greaseerr]

Hi, just noticed on your thread pitch chart for Metric threads there is no fine thread dimensions for 1 to 6mm bolts. Do these exist, I would have thought so. Cheers

[@BoltsandNutscom]

Fine threads are very uncommon for metrics (unlike Inch). They do not exist unless it’s a specialty for 6 and below. Thank you for watching, let me know if I can be of further assistance!

[@karthik.6055]

Can please explain about various thread profiles?

[@BoltsandNutscom]

Hi SK, you can use this here, this should explain more about the profiles and types. www.boltsandnuts.com/user/files/Thread_Pitch_Chart.pdf

Would like to see a proper torque guide for coarse and fine thread fasteners...

[@BoltsandNutscom]

Thank you for the suggestion! I added it to our future video list

[@johnpayne6196]

Great. Thanks.

[@followinglov]

What standard we can go through to know thread profile of metric and unc bolt?

[@BoltsandNutscom]

Hi Rajan, you can use this here, this should explain more about the profiles and types. www.boltsandnuts.com/user/files/Thread_Pitch_Chart.pdf

[@dkh100]

Metic will be labeled iso for standard.
Standard is just what's more popular.

Can i use fine thread nut to coarse thread bolt?

[@BoltsandNutscom]

No unfortunately not.

[@janwrobel9734]

cool

[@lukejones1244]

What happens if you put a fine thread bolt into a course thread hole? And vice-versa?

[@BoltsandNutscom]

Hi Luke, great question. They will not fit because the threads won’t match. If you force it, it will cross thread and will most likely ruin both fasteners. I hope that helps! Thank you Andy

@@BoltsandNutscom what if the holes dont have any thread? I've recently tried to put a m14 x 2 x 100 bolt into a hole that's supposed to accept a m14 x 1.5 x 100 bolt. However the bolt I had didnt fit into the hole. What should I do?
