• 1/4" square drive end complements earlier QDRIVER models with 1/4" hex bit holders
• Pin retains the socket to the square drive
• Freewheels 90° when specified torque is obtained, competitive units without this freewheeling feature can cause overtorquing of the fasteners
• Torques only in the clockwise direction; accuracy within ± 6% from 20–100% full scale
• New textured body provides a non-slip grip
• Comfortable ergonomic tri-lobe grip prevents the device from rolling off a flat surface and being damaged
• Lightweight yet rugged construction
• Easy-to-read torque setting
• Certificate of calibration included insures accuracy in conformance to ASME® B107.300-2010 (B107.14) and ISO 6789:2003
• Torque screwdrivers calibrated to torque standards of the National Institute of Standards Technology (NIST®)
