1/2" Drive Digital Torque Wrench 25-250 ft.lb

This 1/2" drive digital torque wrench covers a range of 25-250 ft.lb or 34-340 n.m with an accuracy of ±2%. It is aimed at mechanics and technicians who need verifiable tightening values for automotive or equipment fasteners. A calibration certificate is included with each unit. The chrome-vanadium steel body receives a six-stage heat treatment and chrome plating for corrosion resistance.

Drive Adapters and Three Operating Modes

The set includes drive adapters and extension bars that allow the 1/2" square drive to work with 1/4" and 3/8" bolt sizes in tight or deep spaces. A reversible ratchet head enables one-hand socket changes. Three working modes — real-time, peak, and preset memory — let the operator match the tool behaviour to the task. The LED display with backlight shows values in Nm, in-lb, ft-lb, or kg-m.

±2% Accuracy Limit and Manual Operation

The ±2% accuracy figure defines the practical limit of the tool; critical joints that demand tighter tolerance will require a more precise instrument. The wrench is a hand-operated ratchet, not a powered multiplier, so the user must supply the force to reach the target torque. No battery life, charging time, or data-logging capability is specified in the supplied data.

Questions about this item

Will the calibration certificate need renewing after a period of use?

Each wrench ships with a calibration certificate showing ±2 % accuracy across the 25-250 ft.lb / 34-340 Nm range; periodic recalibration is recommended per shop practice.

What stops the wrench from over-torquing during a long tightening sequence?

The preset memory mode lets you store a target value and alerts you when that torque is reached, preventing excess force.

How hot does the ratchet head get during continuous daily use?

The chrome-vanadium steel body with chrome-plated coating dissipates heat normally; no unusual temperature rise is reported under typical workshop conditions.
