Strength Of Ice Anchors

A technical paper on the results of testing various types of anchors in ice. They tested Abalakov (V-thread) anchors as well as different lengths and angles of ice screws. Some conclusions:

  • Re-bored ice screws almost as strong as ice screws used in a newly drilled hole
  • Longer ice screws are stronger
  • Vertical V-threads stronger than horizontal
