Gearwrench 85171CERT Micrometer Torque Wrench Calibrated

Product Description

The GEARWRENCH 85171CERT is a micrometer-style torque wrench with a 3/8 inch square drive, designed for clockwise torque application in automotive, mechanical, and general trade service work. It delivers a torque range of 10 to 100 ft/lb (20.3 to 142.4 Nm), with a clockwise accuracy of plus or minus 3 percent, meeting ANSI and ASME B107.300 standards. The wrench ships with a calibration certificate, making it suitable for shops and technicians working under quality-control or fleet-maintenance requirements. A 120-tooth ratchet head provides a minimum arc swing of 3.0 degrees, allowing use in tight spaces with minimal handle travel.

This torque wrench is built for professional use in automotive repair, fleet maintenance, equipment service, and assembly work where repeatable, verified torque is required. The enclosed teardrop ratchet head with a flush-mounted on/off switch and low-profile tube keeps the tool compact in confined fastener locations. Knurled handle grip supports controlled application during high-torque fastening sequences. The highly visible scale markings with 1 in/lb graduation allow precise setting without additional tools or guesswork at the adjustment point.

Compatibility

Designed as a direct-fit 3/8 inch square drive torque wrench for use with standard 3/8 inch drive sockets across automotive, mechanical, and general trade applications.

Installation Notes

This tool is installed and operated by automotive technicians, mechanics, and trade professionals working with fasteners requiring verified torque values. Always return the wrench to its minimum torque setting after each use to relieve spring tension and preserve calibration accuracy. Store in the provided case and avoid dropping or using the wrench as a breaker bar, as impact loads can void calibration. Recertification intervals should follow the shop quality-control schedule or manufacturer recommendation.
