Minimum engagement length of a bolt

AI Thread Summary
The discussion centers on determining the minimum engagement length for an M10x1 bolt. Participants reference an article that provides formulas for calculating this length, particularly for metric bolts. There is a query about whether to use pitch in inches or Imperial units for the calculations. The consensus suggests using all Imperial units for safety, then converting the final measurement back to metric. Understanding the derivation of the formula is emphasized as important for accurate application.

Hey guys.
Could anyone give me an what the criteria for minimum engagement length of a bolt is?
The bolt I'm using is M10x1.

Thanks!

There is more information available if you Google the phrase 'minimum engagement length of bolt'.
Thanks! I read this one
Only thing is, do I just take the pitch in per inch or do I use Imperial units for the entire formula?

Without knowing more about the derivation of this formula, the safest approach would be to use all Imperial units and then convert the resulting length back into mm or cm.

I'm trying to decide what size and type of galvanized steel I need for 2 cantilever extensions. The cantilever is 5 ft. The space between the two cantilever arms is a 17 ft Gap the center 7 ft of the 17 ft Gap we'll need to Bear approximately 17,000 lb spread evenly from the front of the cantilever to the back of the cantilever over 5 ft. I will put support beams across these cantilever arms to support the load evenly
Thread 'What's the most likely cause for this carbon seal crack?'
We have a molded carbon graphite seal that is used in an inline axial piston, variable displacement hydraulic pump. One of our customers reported that, when using the “A” parts in the past, they only needed to replace them due to normal wear. However, after switching to our parts, the replacement cycle seems to be much shorter due to “broken” or “cracked” failures. This issue was identified after hydraulic fluid leakage was observed. According to their records, the same problem has occurred...
