High Compatibility & Laser Calibration: Our calibrated torque screwdriver offers a torque range of 10-70 in-lbs with 1 in-lbs torque increments, making it suitable for a wide range of screw sizes and enabling precise tightening or loosening of screws. The laser-engraved scale allows for easy reading and operation even in low-light environments. Lightweight & High Strength: Constructed with a high-quality aluminum alloy body and featuring a durable alloy steel blade, our torque screwdriver is lightweight for reduced fatigue during use. The alloy steel material ensures excellent wear resistance, corrosion resistance, and prevents deformation or damage, making it suitable for use in high-temperature environments. Over-Torque Reminder: As you approach the preset torque, the torque screwdriver produces an audible 'click' sound and automatically slips, preventing under-tightening or damage caused by over-tightening
