Abstract
A heavy duty, large self-forming socket having a plurality of retractable gripping pins bundled in parallel and held in a frame within a housing is disclosed. The frame is positioned axially within the housing by radially extending, elongated hold elements that are positioned circumferentially around the housing. Slots in the housing exterior allow efficient inspection of the position of holes into which the hold elements are installed. A collar with shelf around the center pin protects the bias spring for the pin from over-compression. The gripping pins may be held to the frame by spring clips and/or a resilient O-ring. An adaptor is attached wherein a secondary operation is used to remove the adaptor from the square end of the socket. The self-forming socket is well suited for use with valves and controls for water, gas, sewage conduits and piping.
