• For TORX PLUS screws
• Tough for hard materials
• 1/4" hexagon drive (Wera connecting series 1)

High-quality bits for recessed TORX PLUS screws. TORX PLUS profile: in comparison to normal TORX profiles, the enlargement of the 6 torque-transferring flanks between the tool and the screw is effected by means of an ellipse-shaped profile design and not a circular one. This means that the power applied when screwdriving is spread over a larger area. Higher torque is transferred, and the service life of the screw and tool is also enhanced. Extra-hard. 1/4" hexagon, suitable for holders as per DIN ISO 1173-D 6.3.

Tough-absorbing bits

Tough-absorbing Wera bits (Z) prevent any premature breakage of the drive tip.

Compared with the "normal" TORX profile, the elliptical instead of circular profile enlarges the 6 flanks that transfer torque between the tool and the screw. This means that the force applied when screwdriving is spread across a larger surface area. Higher torque is transferred, and, in addition, the service life of the screw and tool is lengthened. The so-called centre-lock screws on cutting tools represent a typical use of this type of screw profile. The thermal influences on such holders for carbide insert tips often "bake" the retaining screws so firmly that it is important to have a profile that considerably enhances the loosening torque capability of the screws. For this reason a torque-stable screw profile is necessary to avoid any possible damage to the screw and to exclude the possibility of an otherwise costly machine downtime.
