I realize it is brass so it's a soft material. However after just doing a few adjustments trying to set the pressure the screw stripped out the brass threads. You have to get the torque just right as there is another vent hole on the opposite size of the screw under the black cap area. How tight you make the screw can affect the pressure through the regulator unit... Like I said, it's very finicky... I would recommend either getting a fixed pressure model or look for something else.
