WebIdeally, you want as much thread engagement/depth of thread as possible. Depending on the application, you may be able to get away with much less. For the best strength, you should try to aim for 1-1.5X the bolt diameter to depth ratio. For example, an 8-32 bolt should have roughly (0.136”-204”) thread/material depth. Web9 mei 2024 · 1 Generally you want at least a thread diameter's worth of engagement in a nut/tapped surface. But it also depends on what clamping forces you need or loads you'll be subjected to. 2/3 diameter of thread engagement is a good absolute minimum, so M4 in 3 mm and M3 in 2 mm. – jko May 5, 2024 at 15:06 1 sheet metal screw? machine screw? …
WebLength as well as material composition plays an important role in determination of minimum thread engagement with regards to threaded assemblies, as can be seen with Equation 1. Minimum thread engagement can be calculated by determining the yield points of both materials of the male and female portions, as well as the total strength of the male … Web24 dec. 2005 · If the nut material yield strength is not equal to the bolt material yield strength, you would take the same equation above ( t=0.47d) multiply it by the bolt yield strength then divide by the nut material yield strength. t=.47d*Sy (bolt)/Sy (nut) Grade 8 bolts have a minum yield of 130 ksi and grade 5 is 92 ksi.
