Abstract

The conical projection (5) on the side around the bolt head is coaxial with the threaded part. A hole is drilled out and tapped in a side edge of the well cover (1) and a bolt is inserted into it. When the cover is placed in position, the bolt is screwed out of the hole until the cone locates against the frame, locking the cover.
