• Engineered precision bearing surfaces extend the calibrated life of the M line to as many as 60,000 cycles or more and ensure the most reliable performance possible
• In addition to flawless operation at release, calibration is completely external, unlike traditional mechanism that require disassembly and the replacement of blocks and shims
• Accurate within 3% of reading from 20% of full scale to full scale clockwise and counterclockwise
• Guaranteed against defect in workmanship and materials for 1 year from the date of delivery
• Exclusive Patented Calibration Mechanism allows for calibration in both the clockwise and counter-clockwise directions, plus with regard to spring rate without the disassembly of the wrench
• This protects against contamination of the working mechanism and makes calibration quick and easy
• Exclusive Patented Roller-Release removes over 95% of the friction inherent in other click wrenches, thereby extending life and providing for more reliable operation
