A tool for gaining lateral access to a well includes a head portion configured to advance axially forwardly relative to a lateral access passage. The tool includes a first shaft and a shaft assembly including a second shaft. The second shaft is at least partly received in the first shaft so as to be axially forwardly moveable therewith. In use, axial forward movement of the first and second shafts causes forward advancement of the head portion. The second shaft is axially forwardly moveable relative to the first shaft. The first shaft includes an internal thread and the shaft assembly includes an external thread engaging the internal thread of the first shaft so that relative rotation of the internal and external threads causes the axial forward movement of the second shaft relative to the first shaft without rotation of the second shaft relative to the first shaft.

A tool for installing and removing wheel nut indicators. The tool includes an elongated handle having a first end opposite a second end. An indicator holder is coupled to the second end. The indicator holder includes an end plate and a sidewall. The end plate is substantially perpendicular to the elongated handle and the sidewall extends from the end plate and is substantially perpendicular to the end plate. An inner surface and a cross section of the sidewall forms a teardrop shape. A wheel nut indicator form fits within the indicator holder.

The instant invention relates to a fastener element of a fastening system, a tool for fastening, disengaging and testing the fastener element and a method for providing a fastening system with a closure seal and/or a torque indication. The fastener element of a fastening system, in particular a bolt or nut includes a tool engagement surface that is engageable by a tool, in particular a standard tool for at least partial form locking contact with the tool for fastening or disengaging the fastening system, wherein the tool engagement surface includes at least one weak spot. The fastener element is operable with standard tools and optionally reusable using special tools. Thus, manipulations by unauthorized persons are easily detectable and it is easily determinable whether a predetermined torque has been applied correctly.
