Preset Torque Screwdriver eliminates over/under tightening.

June 26, 2015

Featuring cam-over design, ergonomic TLS Pro series prevents fastener or bolt from being under- and over-tightened. Internal adjustment mechanism, preset using torque tester, is used for setting torque value, and drive is disengaged when tool reaches pre-set torque value. While radial cam design allows for smooth cam action with minimal wear on tool, thrust bearings ensure torque setting is independent of any end load applied by operator. Models range from 0.45–120 lb-in. Read More
