攀登螺栓在户外攀岩和深坑探险和健身房攀岩中很常见，螺栓吊架或固定吊架是固定螺栓和专用吊架的组合，设计用于接受钩环，然后将一根攀岩绳夹在钩环上。通常在螺栓吊架和绳索之间使用快速牵引或吊索，以减少上升、确保和下降时的阻力。在运动攀岩中，螺栓是用来支撑坠落的，但不是用来帮助上升的，而在辅助攀岩中，螺栓可以用来帮助上升。

    Climbing expansion bolts are common in outdoor rock climbing, deep pit exploration and gym climbing. Bolt hanger or fixed hanger is a combination of fixed bolt and special hanger, which is designed to receive shackles and then clamp a climbing rope to the hook and loop.
