Article description
Application:
Controlled bolt tightening in the range of 20 - 850 N-m / 15 - 630 lbf-ft (guide value bolts M7 - 10.9 to M24 - 8.8, M30 - 5.6).
Adjustable, releasing and robust tubular torque spanner with spigot mount for industry and the trades.
Design:
Classified according to DIN EN ISO 6789-2:2017 Type II Class A, including traceable test certificate, calibrated to a maximum permissible deviation of +/- 3 % and thus more precise than the +/- 4 % required by the standard.
For controlled right and left hand tightening.
Robust, lacquered tubular steel construction, with phosphated spigot mount (Ø 16 mm or Ø 22 mm) and high-quality plastic parts.
Ergonomically shaped plastic handle with calibration aid.
Switchover between vernier main scale N-m and secondary scale lbf-ft, to avoid reading errors when setting the desired torque.
With micrometer scale for N-m main scale for setting intermediate scale values.
Jump-off system produces a clear tactile and audible trigger signal.
Ergonomic system for torque adjustment with indicator symbol.
Possibility of quick adjustment with offset screwdriver, not included in delivery.
Secured adjustment system.
Factory calibration gauge: 32 mm (Ø 16 mm) or 56 mm (Ø 22 mm).
Operation only with attachable tools with uniform stitch size - otherwise there may be value shifts.
Depending on the tool insert, work can be carried out either to the front (e.g. open-ended spanner) or to the side (e.g. reversible ratchet and socket spanner insert).
