The CDI 100T-I is a Y-shank preset interchangeable-head torque wrench designed for production lines and repetitive assembly operations in the 20–150 ft-lb (27.1–203.4 Nm) range. At 19 inches long and 2.50 lb it is the largest preset in the CDI T-I family — a step-up in size and shank type that reflects the heavier hardware this range covers.
The Y-shank: what changes from the J-shank presets
The 5T-I through 50T-I use the J-shank (27/64-inch nominal) — CDI's lighter interchangeable head format. The 100T-I uses the Y-shank, CDI's larger interchangeable head format designed for the higher torque loads and larger fastener hex sizes in the 20–150 ft-lb range. Y-shank heads cover open-end, box-end, and flare-nut configurations in the sizes found on airframe structural hardware, landing gear components, cowling attach, and wheel and axle assemblies. J-shank heads are not compatible with the 100T-I — the correct accessory heads are Y-shank format. When specifying additional heads, confirm the Y-shank dimension with your CDI, Williams, or Snap-on Industrial head catalog.
Where repetitive foot-pound production work concentrates in GA
Wheel service on a training fleet involves the same 80–120 ft-lb axle and wheel nut hardware on every identical aircraft. A production line assembling landing gear, cowling, or engine mount subassemblies applies the same structural torque specification on every unit. An MRO running cowling and nacelle installation across a fleet of identical turboprops or piston twins touches the same 30–80 ft-lb attach hardware on every aircraft in the service contract. In each case the preset wrench eliminates per-cycle adjustment, reduces the per-operator error opportunity, and keeps the production rhythm consistent from the first unit to the last.
User-set vs. factory-set: which to order
The 100T-I ships unset — the operator sets the torque value within 20–150 ft-lb. No calibration certificate is included. For environments requiring NIST-traceable calibration documentation at a specific preset value, order the 100T-I-SET, which CDI factory-presets to a value specified at order and ships with a NIST-traceable certificate. Specify the required value when ordering; allow 10 business 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 100T-I does not ship with a calibration certificate — if your QCM or quality program requires documented calibrated torque tools, select the 100T-I-SET.
Built for repetitive foot-pound production work in light and medium GA
- 20–150 ft-lb (27.1–203.4 Nm) — the range covering landing gear, cowling, wheel hardware, and engine mount attach
- Y-shank interchangeable head system — larger format than J-shank, designed for 20–150 ft-lb head sizes
- 19.00" overall length and 2.50 lb — proportioned for the leverage needed at the upper end of the range
- Tamper-proof single-setting mechanism prevents adjustment between production cycles
- Audible click plus tactile impulse confirms torque on each fastener without scale verification
- Cushion grip handle designed for repetitive use across a full production or maintenance shift
- Made in the USA by CDI Torque Products, a Snap-on Industrial Brands company
Where production shops and fleet maintenance operations use the 100T-I
- Wheel and axle hardware on Cessna 172, Piper Archer, and similar light trainer fleets (80–120 ft-lb)
- Brake caliper mounting and landing gear strut hardware on light singles in fleet service
- Engine cowling and nacelle structural attach hardware on repetitive fleet maintenance contracts
- Engine mount attach bolts on smaller piston aircraft in production subassembly environments
- Landing gear subassembly production lines applying identical torque specifications across identical units
- Any repetitive foot-pound operation in the 20–150 ft-lb band where production consistency matters more than per-cycle adjustability
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 100T-I or the factory-certified 100T-I-SET, both come from the same aviation-specialist source that understands production torque documentation requirements from fleet tire service to engine mount subassembly.

QUESTIONS & ANSWERS
The 100T-I uses a Y-shank interchangeable head system — CDI's larger head format designed for higher torque and larger fastener sizes in the 20–150 ft-lb range. The J-shank presets (5T-I through 50T-I) use the smaller 27/64-inch J-shank format for lighter-range work. J-shank heads are not compatible with the 100T-I. The 100T-I is also physically larger at 19 inches and 2.50 lb versus 11 inches and 1.40 lb for the 50T-I, reflecting the leverage requirements of the 150 ft-lb upper range.
The 100T-I is best suited for repetitive operations where the same 20–150 ft-lb torque value is applied to identical hardware across identical units — wheel and axle service on training and utility fleets (80–120 ft-lb), landing gear and cowling structural attach on production subassemblies, engine mount hardware on smaller piston aircraft, and fleet maintenance contracts covering the same aircraft type repeatedly. The preset mechanism eliminates per-cycle adjustment and per-operator variability across the production run.
No. The user-set 100T-I ships without a calibration certificate. For a factory-preset version with a NIST-traceable calibration certificate, order the 100T-I-SET and specify the required torque value at the time of order. CDI factory-presets the wrench and ships it certified; allow approximately 10 business days lead time.
The 100T-I uses the Y-shank interchangeable head system — not the J-shank used on the smaller T-I presets. Y-shank heads in open-end, box-end, flare-nut, and ratchet drive configurations covering the fastener hex sizes in the 20–150 ft-lb range are available from CDI, Williams, and Snap-on Industrial. Confirm the Y-shank dimension when ordering accessory heads to ensure compatibility with this wrench.
