The finest performing ice screw on the market with exclusively designed parabolic shaped threads that have achieved some of the highest pull-out strengths possible. They are carefully turned and machined from steel, nickel plated and affixed with a heat-treated, grain-aligned hanger that is large enough to be clipped with two carabiners. Each screw is also equipped with the Speed Grinder Knob system making them always accessible; no collapsing, folding or rigging accessory spinning handles necessary. With the exclusive thread pitch and tooth pattern, you can be confident in their holding power.
