Bernstein 4-981 Torque Limiter 0.6 Nm for 1/4-inch Bits | High Accuracy & Process Reliability

• DETAILS. Pre-set torque, precise for at least 20,000 clicks; tolerance ±10%; tightening torque 0.6 Nm / 6.1 kgf·cm / 5.3 in-lb; 1/4" magnetic bit holder; 6.35 mm hex (DIN 3126); 1/4" drive; alloy steel; Ø 12 mm; length 28.3 mm (body), 38.3 mm total; weight 21 g.
• For precise screwdriving on bikes, motorbikes, PCs, electronics, model making and workbenches. Turns bit and holder into a torque tool with click signal. Cannot overtighten; 30% higher loosening torque. For hand use; max. 100 rpm with machines.
• TECHNOLOGY: Tested to DIN EN ISO 6789 (±10% tolerance, 20,000 clicks). Patented system with hollow shaft, ratchet and damping cylinder. Core shaft decouples at target torque – no overtightening, constant tension. Regular inspection recommended.
• COMPLETE SOLUTION for work on electronic devices, quick-change systems, robot stations, aerospace, medical technology, or any workstation where precise torque is required.
• BERNSTEIN – FOR OVER 50 YEARS we have been producing electronic and precision engineering hand tools, manufactured as conductive and dissipative ESD tools.

- Preset torque, accuracy tolerance +/-10% - precise and accurate, for 20. 000 clicks. In combination with power tool max. Speed 100 rpm. - Torque adapter length 28 mm (without shaft) - Adapter Ø 12 mm - hexagon. Shaft 6.35 mm (1/4 inch)- Magnet bit holder 6.35 mm (1/4 inch)- Material alloy steel HRC 43-48 - Total length 39 mm - Weight 21 gAreas of applicationThe torque value is preset in the adapter and can be clamped between any standard holding tool and a 1/4 inch bit. This turns each bit holder into a torque screwdriver. Technical product descriptionPrecise and accurate, for 20th 000 clicks. Adapters are primarily suitable for manual operation. In combination with power tools, we recommend max. a speed of 100 rpm, with minimal click repetition. General information: Make your bits and a holder your perfect torque tool. Versatile and with preset torque value for tightening or loosening. This high-precision fine tool with 0. 6 Nm is used in combination with 1/4 inch bits. Often also as a complete solution for working on electronic devices, in quick-change systems, robot stations, aerospace, medical technology or simply on any workbench, wherever the exact torque is important. The "click" sound indicates when the torque is reached, the adapter is therefore not overrotable. When loosening screws, the blocked core shaft does not trigger the torque, so no additional loosening tool is required.
