Tekton TRQ99902 - 2-Piece Split Beam Torque Wrench Set

Split beam and micrometer are not competing choices. They are complementary instruments designed for different categories of work, and the professional tool program eventually has both. The TRQ99902 is the split beam half of that complete program — the TRQ62103 (3/8 in., 20–100 ft-lb) and the TRQ62203 (1/2 in., 40–250 ft-lb, Tekton’s best-selling split beam model) — both sharing the split beam mechanism that removes storage discipline from the daily workflow entirely. No internal spring under tension. Store either wrench at any ft-lb setting. Leave it there. Pick it up tomorrow — still accurate.

Setting is by thumbscrew on both instruments, directly to the ft-lb value required. A flip-up cover with internal locking teeth secures the setting and protects the adjustment knob during the torque sequence. The 10° flex head on both wrenches clears structural geometry and access obstructions without extension adapters or the lever-arm correction math that follows. The dual ft-lb/Nm conversion scale on each wrench body keeps the metric equivalent available without a chart. All-steel construction on both instruments — no plastic parts, no wear-out failure mode under daily repetitive use at either drive size.

Both wrenches arrive in individual HDPE cases with individual serialized certificates of calibration. Pilot John International's ISO 17025-accredited calibration laboratory recertifies both at a single scheduled service event, issuing two NIST-traceable certificates on the same date — one synchronized expiry across the complete split beam program. For wrenches in daily high-cycle production use, a usage-triggered recertification interval is the appropriate tool control architecture. PJi makes that conversation possible.

Drive, 20–100 ft-lb — High-volume repetitive torque sequences on engine mount hardware, propeller flange fasteners, landing gear leg bolts, accessory gearbox components, exhaust system fasteners, and control surface hardware where the same clockwise value is applied multiple times per shift; calibrated at 20, 60, and 100 ft-lb; 2 ft-lb minimum increment; 15.6 in. effective length; 2.1 lb.
• TRQ62203 — 1/2 in. Drive, 40–250 ft-lb (Best Seller) — Wheel and brake assembly torque sequences per ATA 32, landing gear primary attachment and drag brace fasteners, engine mount primary bolts on piston and light turboprop powerplants, propeller hub retention hardware; calibrated at 50, 150, and 250 ft-lb; 5 ft-lb minimum increment; 19.2 in. effective length; 3.7 lb.

Shared Features — Both Wrenches

• Split Beam Mechanism — No internal spring tension at rest; store at any ft-lb setting without calibration drift; calibration stability by design, not by storage discipline
• Set, Lock, Leave — Smooth thumbscrew ft-lb setting; flip-up cover with internal locking teeth; recessed adjustment knob protected during torque sequences
• 10° Flex Head — Clears structural geometry and access obstructions at both drive sizes without extension adapters; 72-tooth ratchet, 5° swing arc
• ±4% Accuracy CW — ASME B107.300-2021 calibrated; tested at three points across each wrench’s full range; serialized certificate of calibration included per wrench
• Dual ft-lb / Nm Scale — Metric reference on each wrench body; no conversion chart needed in mixed-unit environments
• All-Steel Construction — No plastic parts; no wear-out failure mode under daily high-cycle production use
• 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

ft-lb or Nm? Choosing Between TRQ99902 and TRQ99903

The TRQ99902 provides both wrenches with ft-lb primary scales and Nm conversion references on the body — correct for US-primary maintenance environments where AMMs are specified in imperial and metric conversion is occasionally needed. The TRQ99903 provides the same instruments with native Nm primary scales — correct for EASA-regulated maintenance environments, international mixed-fleet operations, and any shop whose AMMs specify torque in Newton-meters as the primary unit. Same mechanism, same calibration standard, same cases and certificates, same set weight. The scale choice is the only operational difference.

Split Beam Alongside Micrometer — The Complete Program

The TRQ99902 split beam set and the TRQ95901/TRQ95902 micrometer sets are not alternatives — they serve different task categories. The split beam is correct for high-volume repetitive clockwise torque work where Set-Lock-Leave workflow, thumbscrew setting speed, and calibration stability without storage ritual reduce error exposure across the production shift. The micrometer wrench is correct for documented bidirectional torque compliance, ±3% ISO 6789-calibrated accuracy, and close-tolerance applications where the maintenance record requires the stricter standard. The professional MRO shop owns both and assigns each to its correct task. PJi stocks both families and can calibrate every wrench in both programs under the same ISO 17025 accreditation.

ISO 17025 Calibration at PJi — Split Beam Program, Both Drive Sizes, One Date

Pilot John International is an ISO 17025-accredited calibration laboratory. PJi recertifies both wrenches in the TRQ99902 set at a single scheduled service event, issuing two individual NIST-traceable calibration certificates on the same date. For wrenches in daily high-cycle production use, a usage-triggered recertification interval — keyed to actual cycle count rather than a fixed calendar date — is the appropriate tool control architecture and the one PJi supports. That documentation package is accepted by FAA Part 145 repair stations, EASA Part 145 maintenance organizations, Part 91/135 operators, and AS9100 / ISO 9001 quality programs. PJi is the only distributor selling this set that can also calibrate every wrench in
