Thread torque specs

  1. Mar 6, 2007 #1
    Hi --

    Does anyone have torque recommendations for a 3/4-14 NPSM thread for S.S. and Aluminum? Thanks! Eric

    Is that a 3/4 NPT? I can't say that I am familiar with the NPSM call out. Perhaps Q has seen it before. I'll do some looking around.

    EDIT: I just found what you're referring to. Straight pipe threads, not tapered. God bless Machinery's Handbook.

    Thanks for the help. This is a new thread for a project at work -- and I am going to be performing the testing to determine our final torque recommendation. I just wanted a starting point to have a figure to keep in mind while testing.
