Description of Black Diamond Express Ice Screws The easiest and fastest placing ice screws on the planet, the Express ice screws have a quicker bite than a pissed- off pit bull thanks to their sublime tooth geometry. The Express screws feature a tapered tube where the teeth cut a hole just larger than the tube itself, for less friction and faster placements. The foldable speed-drive knobs are color-coded for quick length identification and offer uninterrupted 360-degree motion. Stainless steel hangers with secondary clip-in points for belay organization are lighter than previous models, reduce melt-out on sunny routes and won’t rust. Express ice screws are built in five lengths to accommodate a variety of ice conditions.
