Tekton TRQ81122 - 3/8 in. Electronic Torque Wrench

Every mechanical torque wrench in this catalog produces a click. What happens after the click is a matter of trust. The maintenance logbook says a torque was applied. There is no record of what torque was actually achieved. For most aircraft fasteners, that is sufficient. For some, it is not — and for those, the Tekton TRQ81122 is the correct tool. It is a 3/8 inch drive 90-tooth flex head dual-direction electronic torque wrench covering 10–100 ft-lb, and it does not produce a click. It produces data: real-time torque on a backlit LCD as force is applied, timestamped records of every fastener event, a cycle counter, a calibration reminder keyed to usage, and an over-torque event log. The last 50 measurements are stored onboard and retrievable. The maintenance record is not an attestation. It is a record.

Three measurement modes make the TRQ81122 the only tool in this catalog capable of executing modern yield-controlled fastener procedures. Torque mode is the standard: set a target value in ft-lb, in-lb, Nm, or kg-m, tighten to the display target, done. Angle mode uses an onboard gyroscope to measure degrees of rotation, accumulating across multiple ratchet strokes — a 120° angle specification executed in three 40° increments with no count loss. Torque + Angle mode executes both in a single uninterrupted workflow: tighten to torque target, transition directly into angle measurement without changing modes. For engine case and structural fasteners where the AMM specifies an initial torque followed by a defined rotation, no mechanical wrench can execute that procedure as written. The TRQ81122 can.

The onboard crowfoot offset calculator removes the manual math from off-axis torque work entirely. Enter the length offset of any crowfoot or drive adapter, and the wrench recalculates the displayed target automatically — up to ±15 in. (381 mm) in any direction, in all three measurement modes. Set the spec from the AMM. The wrench does the correction. The value applied to the fastener is correct.

When the TRQ81122 needs recertification, Pilot John International's ISO 17025-accredited calibration laboratory provides NIST-traceable certification covering torque and angle accuracy with full measurement uncertainty documentation and traceability chain records — the standard required by FAA Part 145 repair stations, EASA Part 145 maintenance organizations, and AS9100 quality programs that want laboratory accreditation evidence behind every calibration certificate.

Key Features

• Real-Time Electronic Torque Display — Backlit LCD with bold fonts shows live torque as force is applied; no click ambiguity, no threshold guessing; peak measurement displayed and held after release
• ±2% Torque Accuracy, ±1° Angle Accuracy — ISO 6789-calibrated, tested at 10, 60, and 100 ft-lb in both directions; tighter than any mechanical wrench in the Tekton line
• Three Measurement Modes — Torque only, Angle only, and Torque + Angle simultaneously; onboard gyroscope accumulates angle across multiple ratchet strokes for multi-increment rotation sequences
• Torque + Angle for Yield-Controlled Fasteners — Executes initial torque and angle-of-rotation in a single uninterrupted workflow; the only tool in this catalog capable of this procedure as written in modern AMMs
• Onboard Crowfoot Offset Calculator — Enter length offset up to ±15 in. (381 mm); wrench automatically adjusts displayed target in all three modes; no manual formula required
• Four Native Unit Scales — ft-lb, in-lb, Nm, kg-m; switch without a chart or a second tool; covers Boeing, Airbus, ATR, Embraer, and mixed-fleet operations
• 50-Record Timestamped History — Every qualifying torque event stored with peak measurement; retrievable for QA documentation without external data logging hardware
• 10 Programmable Presets — Store mode, target, and unit for recurring tasks; repetition counter tracks multi-fastener sequences and counts to completion
• Calibration Reminder — Set by date, cycle count, or both; usage-triggered tool control intervals without manual tracking
• Over-Torque Event Log — Events above 110% of max torque counted, logged separately, and preserved; highest value retained for reference
• Triple Sensory Feedback — LED color shift (yellow to green), tone pattern change (intermittent to continuous), handle vibration — three simultaneous channels confirm target; sound and vibration can be silenced, lights always active
• 90-Tooth Flex Head, 15° Flex, 4° Swing Arc — 10 teeth engaged simultaneously; 15-degree flex provides more articulation than any other wrench in this catalog for access in tight fastener geometries
• Dual Direction CW/CCW — Both directions ISO-calibrated; bidirectional measurement in all three modes
• Includes — 3/8 in. (F) x 1/4 in. (M) drive reducer, HDPE case, serialized certificate of calibration; 3x AA batteries not included
• 20.0 in. / 2.71 lb. — Compact and light for an instrument with this capability set
• Lifetime Warranty — No receipts, no time limits; Tekton makes it right

Electronic vs. Mechanical — When the TRQ81122 Is the Right Tool

Every mechanical wrench in this catalog has a defined application where it is the correct choice. The TRQ81122 is the right tool when: the AMM specifies torque-plus-angle and a mechanical wrench physically cannot execute the procedure as written; when a QA program requires timestamped torque records rather than technician attestations; when the wrench will be used across multiple unit systems in a shift and unit-switching without a conversion chart matters; when a yield-controlled fastener installation requires angle accumulation across multiple ratchet strokes; or when the tool control program requires usage-triggered calibration reminders rather than fixed calendar intervals. For applications requiring none of these capabilities, a mechanical micrometer or split beam wrench is the simpler and lower-cost solution. For applications requiring any of them, there is no mechanical substitute.

ISO 17025 Calibration at PJi — Covering Torque, Angle, and the Digital Measurement Chain

Electronic torque wrench calibration covers more than a mechanical wrench calibration. It must verify torque accuracy across the full range in both directions, angle accuracy at specified rotation rates, and the integrity of the digital measurement chain from sensor to display. Pilot John International's ISO 17025-accredited calibration laboratory provides NIST-traceable recertification of the TRQ81122 covering all measurement parameters with measurement uncertainty statements and full traceability documentation — the package required by FAA Part 145 repair stations, EASA Part 145 maintenance organizations, Part 91/135 operators, and AS9100 / ISO 9001 quality programs that require laboratory accreditation evidence behind every calibration certificate, not just a manufacturer sign-off.
