TORQUE-indicators
Wera TORQUE-indicators have been factory pre-set to TORQUE values recommended by leading carbide
®
tool manufacturers. Tightening values are precisely related to the size of the TORX , TORX PLUS or hexa-
®
gon socket screw. TORQUE-indicators ensure safe and easily loosened screw connections.
TORQUE Screwdrivers
Adjustable TORQUE screwdrivers:
TORQUE can be set to the required scale value by hand without special tools.
Pre-set adjustable TORQUE screwdrivers:
With pre-set TORQUE, adjustable within a defined range.

Torsion bits
By diverting TORQUE peaks into the Torsion zone of the bit, premature wear and tear is avoided and
dramatically improved service life is achieved.

TORX ®
®
TORX drive profiles transfer TORQUE between tool and screw by line or surface contact rather than point
contact as many other profiles. This protects both the screw profile and the tool profile. It also increases the
amount of TORQUE and power that can be transferred.
TORX BO with borehole
®
TORX tools with a borehole prevent the unauthorised unfastening of safety screws. The screws contain
®
a pin that protrudes into the drive profile so that "normal" TORX tools cannot be used. This pin fits into the
®
®
borehole of TORX BO tools allowing safety screws to be unfastened.
®
TORX with holding function (HF)
The optimised profile wedges the screw to the tool. This is very important in situations where a magnetic
screw holder cannot or must not be used (for instance, jobs involving power tools where metal filings
attracted by a magnet could affect the screwdriving process, or jobs requiring wedging forces and stainless
steel tools, which are non-magnetic because of the nature of the material).
The wedging effect can be guaranteed only for tools made to Acument Global Technologies Inc.
specifications.

®
TORX with pin
The protruding pin that fits into the borehole of the screw makes it easier to centre the tool in
the screw recess.

®
TORX Wedge
The conical TORX profile provides a better fit in the screw. Combined with a great recess depth
®
this produces a pinch effect.
TORX PLUS ®
Compared with the "normal", round TORX profile the elliptical profile of TORX PLUS tools makes it pos-
®
®
sible to increase the size of the 6 flanks that transfer TORQUE between the tool and the screw. The force
applied by the user is distributed across a larger surface area allowing more TORQUE to be transferred and
extending the service life of both the screw and the tool.

®
TORX PLUS HF
Like TORX HF the optimised profile wedges the screw to the tool. This is very important in situations
®
where a magnetic screw holder cannot or must not be used (for instance, jobs involving power tools where
metal filings attracted by a magnet could affect the screwdriving process, or jobs requiring wedging forces
and stainless steel tools, which are non-magnetic because of the nature of the material). The wedging
effect can be guaranteed only for tools made to Acument Global Technologies Inc. specifications.
