Capri Tools 21-Piece Handle 1/4-in Hex Multi-Bit Screwdriver Set

This 10-in lb to 50-in lb torque limiting torque screwdriver comes with a 1/4-in female hex drive and a super comfortable grip. The torque adjustment is in 1-in lb increments to achieve maximum precision. An internationally recognized calibration certificate is included, which validates this product as having a calibration tolerance of +/-6% and meeting DIN ISO 6789 and ASME B107.300-2010. The torque adjustment is intuitive and automatically locks after each setting is selected. The torque limiting feature causes the screwdriver to slip once selected torque is reached in order to avoid damage to the screw being driven.
