Tekton TRQ99903 - 2-Piece Split Beam Torque Wrench Set Nm

The Airbus AMM does not speak foot-pounds. The ATR Component Maintenance Manual does not speak foot-pounds. For the EASA Part 145 maintenance organization, the US MRO maintaining European-type aircraft under bilateral agreement, and the multi-type operator whose line maintenance teams work across American and European airframes in a single shift, the unit scale on the torque wrench is not a preference — it is a documentation accuracy requirement. The Tekton TRQ99903 is the Newton-meter split beam production program: the TRQ62131 (3/8 in., 26–130 Nm) and TRQ62231 (1/2 in., 70–350 Nm), both on the split beam mechanism that requires no storage discipline and produces no calibration drift from an improperly stored spring, both scaled natively in Nm to match the AMM page directly.

Both wrenches share the same split beam workflow. No internal spring tension at rest — store at any Nm setting, on any bench, without calibration drift. Set with a smooth thumbscrew directly to the Nm value in the task card. Lock the flip-up cover. Apply torque to the click. The 10° flex head on both drive sizes clears Airbus pylon geometry, ATR propeller access areas, landing gear structure, and confined maintenance environments without extension adapters. The ft-lb conversion scale remains on both wrench bodies for when the conversation crosses back to imperial — but the working scale is Newton-meters, the way the AMM writes it.

The TRQ62231's documented effective length of 488 mm supports the off-axis crowfoot torque correction calculations that Airbus and ATR AMM task cards specify explicitly on obstructed fasteners — eliminating field measurement and ensuring the correction factor is traceable to the manufacturer's documentation. No competitor listing for this set provides that measurement.

Pilot John International's ISO 17025-accredited calibration laboratory recertifies both wrenches at a single service event, issuing two NIST-traceable calibration certificates in Newton-meters with measurement uncertainty statements and full traceability chain records on the same date. For EASA Part 145 and AS9100 quality programs that require laboratory accreditation evidence — not just calibration results — PJi's ISO 17025 certificate is that evidence. One service date. Synchronized expiry. Complete Nm split beam program.

Shared Features — Both Wrenches

• Native Newton-Meter Scale — Set directly to the Nm value in the AMM without conversion; calibration test results documented in Nm on both certificates
• Split Beam Mechanism — No internal spring tension at rest; store at any Nm setting without calibration drift; calibration stability by design, not by storage discipline
• Set, Lock, Leave — Smooth thumbscrew Nm setting directly from AMM value; flip-up cover with internal locking teeth secures setting; recessed adjustment knob protected during torque sequences
• 10° Flex Head — Clears Airbus pylon geometry, ATR propeller access, landing gear structure, and confined access on both drive sizes; 72-tooth ratchet, 5° swing arc
• Documented Effective Lengths — 397 mm (TRQ62131) and 488 mm (TRQ62231); supports AMM-required off-axis crowfoot torque correction calculations without field measurement
• ±4% Accuracy CW — ASME B107.300-2021 calibrated; tested at three Nm points across each wrench’s full range; individual serialized certificate included per wrench
• ft-lb Conversion Scale — Imperial reference on each wrench body; available without a chart when the conversation crosses back to ft-lb
• Individual HDPE Case Per Wrench — Two separate cases; each wrench and its certificate stored and transported independently
• Tekton Recertification Available — Both wrenches supported by Tekton’s manufacturer recertification service
• Total Set Weight: 5.8 lb.
• Lifetime Warranty — No receipts, no time limits on both instruments

TRQ99903 Nm vs. TRQ99902 ft-lb — Which Set Is Correct?

The TRQ99902 (ft-lb) and TRQ99903 (Nm) are mechanically identical — same split beam mechanism, same 10° flex head, same 72-tooth ratchet, same ASME calibration standard, same cases and certificates, same 5.8 lb. total weight. The only operational difference is the primary scale. Choose TRQ99902 if your AMMs specify torque in foot-pounds and metric is a reference. Choose TRQ99903 if your AMMs specify torque in Newton-meters and working natively from that scale — without a conversion step on every task card — is a documentation accuracy and error-reduction requirement. For EASA Part 145 operations and US facilities maintaining European-type aircraft under bilateral agreements, TRQ99903 is the correct set.

ISO 17025 Calibration at PJi — Nm Certificates, Both Wrenches, One Date

Pilot John International is an ISO 17025-accredited calibration laboratory. PJi recertifies both wrenches in the TRQ99903 set at a single scheduled service event, issuing two individual NIST-traceable calibration certificates in Newton-meters with measurement uncertainty statements and full traceability chain documentation on the same date. For EASA Part 145 approval holders and AS9100-certified maintenance organizations whose quality systems require laboratory accreditation evidence — not just calibration results — PJi’s ISO 17025 accreditation is that evidence. Synchronized calibration expiry means one interval, one service event, no staggered dates across the complete Nm split beam program. PJi is the only distributor selling this set that can recertify every wrench in it, in Newton-meters, under an internationally recognized laboratory standard.
