GearWrench 85079 1/2-Inch Drive Digital Electronic Torque Wrench with Angle Tracking

The GearWrench 85079 1/2-Inch Drive Digital Electronic Torque Wrench is a precision angle-tracking fastener driver engineered for torque-plus-angle tightening protocols on automotive cylinder heads, main bearing caps, suspension struts, and industrial machinery flanges. Delivering a torque measurement range of 25 to 250 ft-lb (34 to 340 Nm) with ±2% clockwise torque accuracy and ±1% angular rotation precision, this 25-inch alloy steel tool features a 72-tooth flex-head ratchet with a 5-degree swing arc. Equipped with ten programmable memory presets, peak torque and angle tracking modes, an oil-resistant dual-durometer handle, and a tri-alert warning system (vibrating handle, buzzer, and LCD display), this tool meets or exceeds ASME B107.28M and B107.300 specifications.

Best Used For:

  • Torque-To-Yield Engine Fastener Installation: Executing multi-stage torque and angular rotation sequences on automotive cylinder head bolts and crankshaft main caps.
  • Automotive Suspension & Drive Hub Maintenance: Torquing heavy-duty wheel spindle nuts, control arm pivot bolts, and brake caliper brackets within factory tolerances.
  • Industrial Machinery Flange Assembly: Calibrating high-stress mechanical fasteners across hydraulic pump mounts, gearbox housings, and structural steel flanges.

Key Performance & Safety Features

  • Precision Digital Angle Tracking: Measures rotational degrees directly to execute torque-plus-angle fastener specs without separate angle gauges.
  • Flex-Head 72-Tooth Ratchet Mechanism: Operates on a narrow 5-degree swing arc with a pivoting head to clear obstructions in cramped engine bays.
  • Tri-Alert Target Warning System: Combines handle vibration, an audible alarm buzzer, and a flashing LCD screen to signal target torque arrival.
  • 10 Programmable Memory Presets: Stores frequently used torque and angular specs for rapid recall during repetitive multi-fastener jobs.
  • Oil & Solvent-Resistant Dual-Durometer Handle: High-traction cushion grip protects internal electronics and resists degradation from shop chemicals.
  • Five Selectable Measurement Units: Converts torque values instantly between ft-lb, in-lb, Nm, kg-m, and kg-cm for global specification compliance.

What's Included

  • (1) GearWrench 85079 1/2 In. Drive Flex Head Electronic Torque Wrench with Angle Tracking
  • (1) Protective Blow Molded Storage Case
