    Confused fastener torque to axial force

    I am designing an temporary 6061 t6 aluminum locking ring that will fit inside a piece of pipe.
    The ring will be drilled and tapped for radial set screws grade 5 material 1.5" -6 threads.
    The set screws will be tightened radially into the inside diameter of the pipe thereby locking the ring in place temporarily.
    I intend to use 150 ft-lbs torque on the set screws. How can I calculate the axial force of each screw on the pipe ID due to the torque applied to this set screw.

    Tell me and I forget. Teach me and I remember. Involve me and I learn.

    I tried that and got like 6500 lbf.
    > It doesn't take in consideration of the different materials.??

    That is the approximate axial force applied by torque regardless of material. The only consideration is friction.
