A 6 sided adapter used to key the rim to the axle on many models (especially monster trucks, truggies, and 1:8 buggies). The hex is keyed to the axle pin with a slot on the back, and a hex shaped recess in the rim is keyed to the hex - the whole thing is held together with the wheel nut. Rims are available in various hex sizes, with the most popular being 10 mm (sedan size), 14mm (maxx size), 17mm, 23mm, and 27mm (for 1:8 buggies and truggies).
