MetalMule Welcome to the Forum from Canada. May I suggest to you to buy a socket with the correct sized bit in it and that will break it free with a 3/8" rachet. When its loose and out, place a No.61 O-ring on the screw before re-tighting it to around 40 inch lbs. Problem solved and very cheaply as well. With this in place it won't come loose unless you want it to.
