Description

Wiha 28589 TORQUEVARIO Bit Set 59-Piece

Audible Dynamic Click-Release Slip Clutches. Official N.I.S.T. Traceable Certificate of Calibration. 59-Piece Master Insert Bit & Socket Array.

The Wiha TorqueVario-S 59-Piece Master Bit Set brings certified fastener accuracy, high-capacity component protection, and extensive drive profile versatility directly to your advanced industrial maintenance station. Purpose-built to eliminate the costly structural damage of over-tightened threads, the loose vibrations of under-torqued assemblies, and the production delays of using uncalibrated hand tools, this premium German-engineered adjustable torque driver system represents a commercial quality standard. It equips aerospace assembly technicians, delicate automotive mechanics, high-end electronics engineers, and precision manufacturing crews with a master torque array optimized to tighten sensitive field sensors, calibrate machinery control terminals, seat soft carbon parts, and manage critical data hardware safely.

Exceptional metallurgical durability and rigorous, traceable quality control serve as the foundation of this high-capacity Wiha 28589 Torque Control Set. Engineered to comply with strict EN/ISO 6789 and ASME B107.14M safety parameters, each tool is individually serialized and packed with an official traceable certificate of calibration. The handle integrates a distinct window scale allowing users to read torque settings clearly, which adjust quickly using the included adjustment tool. Squeezing down on fasteners engages an internal mechanical slip clutch that emits an audible click and releases physical tension automatically the instant your targeted torque is reached. The entire 59-piece payload features precision-machined CVM steel bits and 14 separate sockets housed in a rugged metal organizer case.

Why the Wiha® 28589 TorqueVario-S® Master System Rules the Production Line:

  • 59-Piece Master Industrial Curation: Packs an extensive, cross-industry lineup containing 40 precision-machined insert bits, 14 robust sockets, 2 torque handles, and adapter tools.
  • Traceable Calibration Accuracy: Every kit features an individual serial number and an official certificate of calibration meeting EN/ISO 6789 and ASME quality guidelines.
  • Audible Automatic Reset Slip Clutch: Releases tension instantly when your target torque is reached, emitting a distinct click to prevent strip out.
  • Direct Window Reading Scales: Features clean, highly legible numerical window displays right on the handles to make target selection quick and error-free.
  • Heavy-Duty Protective Metal Case: Enclosed inside a rugged workshop metal container fitted with custom foam cutouts to keep every specialty bit safely organized.

Frequently Asked Questions

+ Which exact torque handles and range capacities are bundled inside this 59-piece set?
The 28589 master configuration bundles two separate adjustable drivers to give you seamless coverage across tiny micro-fasteners and standard hardware. It includes one TorqueVario-S handle rated for 10 to 50 Inch-Ounces (adjusting in 0.5 in-oz steps) and a second handle rated for 5 to 10 - 15 Inch-Pounds (adjusting in 0.5 in-lb steps). This broad range makes it ideal for handling everything from fragile circuit frames up to industrial engine controls.
+ Does this tool stop turning automatically once the targeted torque level is reached?
Yes, it utilizes a premium mechanical clutch system. The instant your pre-set torque target is reached, the internal slip clutch releases tension automatically and emits a distinct, audible click. Squeezing the handle further will simply cause the internal mechanism to slip continuously without adding extra rotational force to the screw, completely protecting fragile components from accidental over-tightening.
+ How often do these TorqueVario-S handles need to be sent in for re-calibration?
To keep the tools completely aligned with global EN/ISO 6789 and ASME quality benchmarks, industrial guidelines recommend getting the handles re-calibrated after 12 months of constant workplace service or upon hitting 5,000 active click cycles—whichever occurs first. To preserve the internal calibration spring from developing structural fatigue during down periods, always adjust the handle back down to its lowest numerical setting before storing it in the metal case.
+ Are these adjustable torque handles insulated to safely handle active live electrical currents?
No. The handles in the 28589 kit are molded from standard SoftFinish dual-durometer comfort plastics and use all-steel internal mechanisms. They are not insulated and do not carry an official VDE or 1,000V dielectric protection certification. For active live-panel tracking or high-voltage switchgear repairs, you must purchase Wiha's dedicated insulated torque lines featuring distinct red and yellow VDE branding.
