? Torque wrenches are designed for use on production lines and other applications where a specific torque is required for repetitive opperations. The design, fabrication and materials used have been developed in coordination with major manufacturers in actual production use. ? Five Models with torque range from 10 in. lbs. to 200 Ft Lbs. ? Featruring a durable, non-slip cushion grip ? Uses universal round shank heads ? Audible click and feel impulse torque control mechanism ? Tamper proof torque setting for production line use ? Torque values can be calibrated in english and metric setting ? Accuracy: +/ 3% of indicated value, in direction of torque indicator, from 20% to 100% of full scale. ? Meets or Exceeds ASME B107.14-2004, ISO 6789
