Bolt tensioning is now the preferred method of tightening

bolts on all critical applications and the HTF range of

tooling provides the optimum solution to bolt tensioning

problems.

The tool consists of only two parts, a threaded load cell,

and a bridge with integral nut socket. It is simple,

compact, light in weight, and is supplied complete and

ready to use.

The HTF series is a proven design in use on bolting

applications throughout the world.

Ram stroke is 8mm (0.315 in) for HTF0 to HTF7 andis 10mm (0.39 in) for HTF8 to HTF11.

The fast simple safe and accurate method oftightening bolts and studs.

Fixed thread design gives compact economical easy tohandle tooling.

Maximum tool operating pressure -1170 bar (17,000 psi).

Minimum stud protrusion is 2 x bolt dia above thetool seating face.
