Vertical caving terminology and methods > Rigging methods and equipment
A handheld tool shaped like a chisel, with a screw thread on the end. This is used to hold a spit nut, and is hit with a hammer in order to drill the nut slowly into the wall. Slowly rotating the tool after each hammer hit allows it to drill more effectively. Used when bolting up an aven or initially setting up the anchors on a pitch, which can then be used for all future rigging. Bolting tools must be connected to a gear loop via a tether, to avoid dropping them.
