Ergonomically shaped, convenient black plastic handgrip with calibration aid. Dual scale N·m and lbf·ft below a window with a magnifying-glass effect. With micrometre scale for main N·m scale for setting interim values. Release system triggers a tactile and audible signal. Ergonomic system for torque adjustment. Factory depth gauge: 32 mm (Ø 16 mm) or 56 mm (Ø 22 mm). Operation only with end fittings with standardised depth gauges, otherwise inaccuracies can arise.
