Precision Instruments M3R250F 1/2-inch Dr. Micrometer Click Type Torque Wrench - 50-250-pound -foot

Made by: Precision Instruments

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. Along with flawless operation at release, calibration is completely external, unlike classic mechanism that require disassembly and the replacement of blocks and shims.Extremely Accurate-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 providing that they have been used according to instructions. Exclusive Patented Calibration Mechanism-This patented mechanism permits 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 make calibration quick and easy.Exclusive Patented Roller-Release - This patented feature removes over 95% of the friction inherent in other click wrenches thereby extending life and providing for more reliable operation.All "M" Series meets or exceeds all applicable requirements of: ANSI / ASME B107.14M, GGG-W-00686C, BS6073: 1988, ISO6789Specifications: Drive Size: 1/2"; fixed ratchet head, Range : 50-250 lb.in.Graduations: 1 pounds ft.Length: 22-1/2"Accuracy: 3% accuracy from 20% of full scale to full scale in both the clockwise and counter-clockwise directions.
