    I WOULD LIKE TO KNOW THE MEANING OF RUN OUT

    I LIKE TO UNDERSTAND WHAT MEANS THE FOLLOWING SENTENCE

    the run out are at both ends , and would be corrected by the finish machine as dia are much bigger then finish dimensions

    Re: Run Out

    Is it a leak?

    Or are these tubes that carry liquid water away?

    I'm certainly not sure what this means, but if it referred to a liquid, Susie, wouldn't the verb be singular,

    "the run out is at both ends ..."

    More context would be really helpful, Cele. It might describe what happens in a machining cycle where as a piece is fed in and as the same piece leaves the machine, a portion of the material is not machined/planed properly. But this can be corrected in a later "machining" procedure because the material is left larger than the final finish dimensions.

    Or, I'm completely out to lunch on this.

    Hi cele_sp,

    There are a few excerpts of different articles concerning the matter in question.

    Screws are generally made from low to medium carbon steel wire, but other tough and inexpensive metals may be substituted, such as stainless steel, brass, nickel alloys, or aluminum alloy. Quality of the metal used is of utmost importance in order to avoid cracking. If a finish is applied to the screw, it must be of a compatible makeup. Steel may be coated or plated with zinc, cadmium, nickel, or chromium for extra protection.

    I think that in the present case “run out” = “wear out” = “wearing out”

    The ends are worn out (threadbare) so they have to be corrected, because there is an apparent eccentricity and an intolerable runout (play, beating).
