CDI 10T-I – J-Shank Preset Torque Wrench

The CDI 10T-I is a J-shank preset interchangeable-head torque wrench designed for production lines and repetitive assembly operations requiring consistent, tamper-proof torque in the 30–250 in-lb (3.4–27.7 Nm) range. At 11.00 inches and 0.90 lb, it is the widest-range J-shank preset in the CDI T-I family — and the one a production or overhaul shop reaches for when the fixed torque specification falls anywhere in the broad band covering the majority of engine accessory and airframe small-fastener work.

The widest-range J-shank preset in the CDI lineup

The 30–250 in-lb span covers the full production range of engine accessory work. At 30 in-lb it handles light accessory and instrumentation fasteners; through 60–150 in-lb it covers magneto mounting hardware, fuel system fitting and carburetor attachment, vacuum pump and alternator bolts on Continental and Lycoming accessories, and general airframe structural hardware on production assemblies. Toward 200–250 in-lb it reaches intake manifold studs, upper-range accessory case hardware, and heavier panel attach points. A production shop running identical assemblies sets this wrench once and runs the batch — one tool, one setting, the full range of the production spec.

How it differs from the 5T-I and 10ST-I

The 5T-I (10–50 in-lb) is the preset for connector backshell and light avionics hardware. The 10T-I (30–250 in-lb) is the preset for engine accessory, fuel system, and airframe structural production work where the target value falls anywhere in a broader band. The 10ST-I covers the same 30–250 in-lb range in a short-tube design that extends the front of the wrench forward, reducing the force required to reach torque in installation geometries where the operator's body position limits load application — useful on engine accessory installations where clearance restricts how the operator can push.

User-set vs. factory-set: which to order

The 10T-I ships unset — the operator sets the torque value within 30–250 in-lb. No calibration certificate is included. For environments requiring NIST-traceable calibration documentation at a specific preset value — Part 145 shops, AS9100 facilities, or programs with torque traceability requirements — order the 10T-I-SET, which CDI factory-presets to a value specified at order and ships with a NIST-traceable calibration certificate. Specify the required value when ordering; allow 10 days lead time.

Documentation and compliance

Meets ASME B107.14 and ISO 6789. Accuracy: ±4% CW of indicated value from 20–100% of full scale. The user-set 10T-I does not ship with a calibration certificate — if your QCM or quality program requires NIST-traceable documentation for preset torque tools, select the 10T-I-SET.

Built for production-line consistency across the engine accessory range

• 30–250 in-lb (3.4–27.7 Nm) — the widest range of any J-shank preset in the CDI T-I family
• 11.00" overall length and 0.90 lb — compact enough for production line and bench assembly work
• J-shank (27/64") accepts open-end, box-end, flare nut, and ratchet drive heads — 100+ configurations
• Tamper-proof single-setting mechanism prevents adjustment between production cycles
• Audible click plus tactile impulse confirms torque on each fastener without checking a scale
• Cushion grip handle designed for repetitive use across a full production shift
• Made in the USA by CDI Torque Products, a Snap-on Industrial Brands company

Where production shops and overhaul facilities use the 10T-I

• Magneto mounting hardware on Continental and Lycoming engine accessories (60–100 in-lb)
• Carburetor and fuel injection attachment hardware on engine accessory production lines
• Vacuum pump and alternator mounting bolts on engine accessory overhaul and installation
• Fuel system fitting and B-nut hardware requiring consistent documented torque across identical assemblies
• General airframe structural fastener production — subassemblies, panel attach, and bracket hardware
• Any production or overhaul operation where the same torque value is applied repeatedly to identical fasteners in the 30–250 in-lb band

Why source aviation tooling from Pilot John International

Pilot John International is an aviation-specialist distributor — not a general industrial catalog. We serve Part 145 repair stations, FBOs, MRO operations, and flight schools across the U.S. Whether your program calls for the user-set 10T-I or the factory-certified 10T-I-SET, both come from the same aviation-specialist source that understands production torque documentation requirements from the assembly line to the QCM audit.
