H.D. has 1/2" OD, 3/8" ID aluminum tubing, works just fine. This provides the 1/16" wall thickness. No way 50 or 60 in. lbs. of torque on a screw is going to compress this.
Whatever you use, take a grinding wheel and cut a number of grooves/slots around the outside to help bond the pillar in place.
