Tentec, a U.K.-based designer and manufacturer of bolt tightening equipment, has added new foundation bolt tensioning tools to its Aero range. The Aero Model WTF offers a 25-millimeter piston/ram capability for one-pull, uninterrupted tensioning.

According to the company, these tools can be supplied to suit many different thread forms, such as Williams and Dyson threaded bars and the more conventional ISO metric and imperial unified thread forms.

Versatility is also key in the design of the Model WTF. As the amount of thread protruding can vary significantly from turbine to turbine, the tensioning tool has been designed to work in two different ways. When there is long stud protrusion from the foundation hexagon nut, a spare nut can be used on top of the Aero WTF tensioner, whereas with a short stud protrusion, an extended length puller can be used. This reaches down inside the tensioner to grip onto the short stud protrusion.

All Aero WTF tensioners have been designed for use with structural hexagon nuts to DIN 6915 and more conventional nuts to DIN 934. WTF is also designed for nuts that use washers to DIN 6916 & DIN 125.
