Tekton TRQ98901 - 2-Piece Electronic Torque Wrench Set

Every other set in this catalog is a collection of mechanical instruments. The TRQ98901 is different in kind, not just in specification: it is a 2-piece electronic torque wrench set pairing the TRQ81122 (3/8 in., 10–100 ft-lb) and TRQ82123 (1/2 in., 30–300 ft-lb) — the two electronic instruments that together cover the full documented torque spectrum for structural, powerplant, and landing gear aviation maintenance, from 10 ft-lb to 300 ft-lb, without a mechanical click wrench in the workflow. This is not a coverage decision. It is a program decision: the choice to make data-backed, timestamped, electronically documented torque events the standard across the two drive sizes that handle the most consequential fastener work on the flight line.

Both instruments share the same electronic architecture. Three measurement modes — Torque, Angle, and Torque + Angle — make both wrenches capable of yield-controlled fastener procedures as written in modern AMMs: initial torque applied to the live LCD display, then immediate transition into angle measurement via the onboard gyroscope that accumulates rotation across multiple ratchet strokes without count loss. No mode change. No tool change. No mechanical click wrench can execute that procedure. Both instruments in the TRQ98901 can. Every qualifying event on each wrench is stored in a 50-record timestamped history buffer, with over-torque events logged separately, cycle counts accumulating in onboard memory, and calibration reminders keyed to date, cycle count, or both. The onboard crowfoot offset calculator adjusts displayed targets automatically up to ±15 in. (381 mm) in all three modes. Four native unit scales — ft-lb, in-lb, Nm, kg-m — cover every AMM specification language without conversion.

Pilot John International's ISO 17025-accredited calibration laboratory recertifies both instruments at a single scheduled service event — covering torque accuracy, angle accuracy, and the digital measurement chain on each wrench — issuing two NIST-traceable certificates on the same date. Synchronized calibration expiry. Complete documented electronic program. No staggered intervals, no separate tracking.

• Calibration Reminder by Date and/or Cycle Count — Usage-triggered tool control on both instruments without manual tracking
• Over-Torque Event Log — Events above 110% of maximum logged separately on both wrenches; highest value retained per instrument

Electronic vs. Mechanical — Why Both Drive Sizes Matter in Electronic Format

The TRQ81122 and TRQ82123 are available individually. The TRQ98901 set is the correct purchase when both instruments are needed simultaneously — which is the case for any shop building a complete electronic torque program for 3/8 and 1/2 inch drive work. The 3/8 inch electronic wrench handles mid-range structural, powerplant, and accessory work requiring documented records or angle-of-rotation procedures. The 1/2 inch electronic wrench handles the primary structural and high-torque yield-controlled fastener work that sits above the 3/8 inch range. Both are needed. Both calibrate from the same ISO 17025-accredited lab on the same service date. The set is the program.
