The Rawl 5-Piece sleeve bolt is a construction grade fastener that is commonly used as a climbing anchor. Expansion is created by tightening a threaded bolt which draws a tapered cone expanding a sleeve against the walls of the hole. The 5-Piece bolt works well in soft rock where maximum expansion is required.
