Our Preset Torque Wrenches are specialized tools designed to ensure the tightening of ER16, ER20, ER25, and ER32 collet nuts to their spec. Featuring factory-preset torque values, these wrenches prevent the risk of over-tightening—which can deform collets—or under-tightening, which can lead to tool slippage. Using these wrenches is critical for maintaining the guaranteed runout and proper tool clamping forces of your HSK 63F and ISO 30 tool holders.
