Ice screw

An ice screw. Some modern screws like this one now have a handle to assist entry and removal, whereas early models did not.

An ice screw is a threaded tubular screw used as a running belay or anchor by climbers on steep ice surface such as steep waterfall ice or alpine ice during ice climbing or crevasse rescue, to hold the climber in the event of a fall, and at belays as anchor points.[1][2]
