The unique cam design minimizes friction due to reduced contact area between cam and internal tube wall

Cam retains and releases lubricant where needed, reducing friction for more accurate and repeatable torque values

The hardened chrome cam and spring results in improved durability and calibration retention

Metal knurled handle design improves positive grip

Accurate to ±3% clockwise from 20–100% full scale

7,500 cycles between tool re-calibration less time out of service for calibration

Each torque instrument, as calibrated at the factory, is certified to meet the accuracy specified in ASME® B107.3
