Abstract: In some examples, an apparatus comprises a surface and at least one flange extending from the surface. The fitting is operable to rotate from a first angular position to a second angular position based on contact between the at least one flange and a fastener and a torque applied to the fastener. In the first angular position, a gap separates the at least one flange from a barrier. In the second angular position, the at least one flange prevents rotation of the fastener based on contact between the barrier and the at least one flange. In some embodiments, the at least one flange comprises a plurality of flanges.
