Dimensioning of a threaded axial gap

A tubular threaded joint for the drilling, operation of hydrocarbon wells, transport of oil and gas, transport or storage of hydrogen, carbon capture or geothermal energy, comprising a male tubular element and a female tubular element, each of said male or female tubular elements comprising respectively a male threaded portion and a female threaded portion, one or the other of the male or female threaded portions optionally comprising an anticorrosive and/or lubricating solid coating, said male threaded portion and female threaded portion comprising respectively at least one male threading tooth and one female threading tooth and a threaded axial gap TAG ensuring a space, in the mounted state, between a stab flank of said male threading tooth and a load flank of said female threading tooth, wherein said threaded axial gap TAG is greater than or equal to a minimum gap TAGmin such that:
