A stud ( 20 ) includes a shaft ( 24 ) having an integrated stop washer ( 26 ), helical threading ( 23 and 25 ) on opposing sides of the integrated stop washer, and an integral driver mechanism ( 22 ) having a diameter smaller than the diameter of the shaft. The stud can mate with a wing-nut ( 18 ) that can be placed over the integral driver mechanism. The stud can further include an integral fluted thread cleaning feature ( 32 ). The cleaning feature can clean the threads ( 14 ) on an anchor ( 17 ) having an inner sleeve ( 12 ) and an outer sleeve ( 16 ) as the stud is being threaded into the anchor. The stud can further include a compressible washer ( 28 ) abutting against the integrated stop washer. The stud 20 can further include an optional spacer ( 30 ) abutting against the compressible washer when under compression. The stud can serve as a setting tool for the machine screw anchor arrangement.
