Sapim Polyax brass nipples are nickel treated to increase corrosion resistance. The head's special form allows higher spoke angles preventing bends. The 12 mm nipples have a 2 mm thread for rims with Ø 3.5 mm holes.
Double Square nipples were developed for special centering machines. This nipple form is becoming more and more popular because the visible surface of the tightening areas does not get damaged. Double Square nipples get tightened from the inner side of the rim.
