CDI 50T-I-SET – Factory Preset Torque Wrench w/Cert

The CDI 50T-I-SET is a J-shank preset interchangeable-head torque wrench covering 15–75 ft-lb (20.3–101.7 Nm) — factory-preset by CDI to a torque value you specify at order, arriving with an individually serialized NIST-traceable certificate of calibration. The certificate is the reason this variant exists. For any operation where the preset torque tool must be documented and traceable — Part 145 shops, AS9100 facilities, engine warranty programs — the 50T-I-SET is the correct purchase over the user-set 50T-I.

How to order: specify the torque value

The 50T-I-SET ships with the value CDI sets at the factory — you must specify that value when placing the order. Do not order this SKU without specifying the required preset torque. A 50T-I-SET received without a specified preset value cannot be adjusted by the buyer after the fact and retain its documented calibration status. Allow approximately 10 business days from order for CDI to preset and certify the wrench. Plan purchase lead time accordingly — this is not a same-day or next-day item.

Why Part 145 shops need the -SET, not the user-set 50T-I

A Part 145 shop whose QCM requires calibrated, NIST-traceable torque tools for all torque applications on certificated aircraft needs documented evidence of what the preset tool is set to and that it was calibrated against a traceable standard. The user-set 50T-I — where the shop's own operator sets the value without an accompanying calibration certificate — does not satisfy that requirement. The 50T-I-SET does: you specify 30 ft-lb (or whatever the applicable spark plug or hardware value is), the certificate says "preset to 30 ft-lb, calibrated to NIST-traceable standards," and that document files cleanly into your tool control system. That is the auditable, defensible practice.

The spark plug installation application

Continental and Lycoming engines specify spark plug installation at 300–420 in-lb (25–35 ft-lb) depending on thread size and revision — values that fall in the lower-middle of the 50T-I-SET's accurate working band. Setting this wrench to the applicable plug torque value and filing the factory certificate in the tool control record creates a documented torque tool practice that satisfies both engine manufacturer requirements and FAA Part 145 QCM scrutiny on spark plug maintenance records.

Documentation-ready — the certificate is included

Every 50T-I-SET is individually serialized at the factory, calibrated at the specified preset value against NIST-traceable reference standards, and ships with a matching certificate documenting the preset value, serial number, calibration date, and traceability chain. Meets ASME B107.14 and ISO 6789. Accuracy: ±4% CW of indicated value from 20–100% of full scale.

Identical hardware to the 50T-I — with factory preset and certificate

• J-shank (27/64") accepts open-end, box-end, flare nut, and ratchet drive heads — 100+ configurations
• 15–75 ft-lb (20.3–101.7 Nm) in the same 11.00" body and 1.40 lb weight as the 50T-I
• CDI factory preset to the torque value specified at order — tamper-proof after presetting
• Individually serialized NIST-traceable calibration certificate included — files directly into tool control
• Approximately 10 business days lead time for factory presetting and certification
• Tamper-proof mechanism prevents adjustment between production cycles after factory preset
• Audible click plus tactile impulse confirms torque on each fastener without scale verification
• Cushion grip handle for repetitive use across a full maintenance or production shift
• Made in the USA by CDI Torque Products, a Snap-on Industrial Brands company

Where certificated maintenance programs require the 50T-I-SET over the user-set 50T-I

• Part 145 repair station spark plug installation programs where QCM requires documented calibrated torque tools
• Engine warranty service programs where the manufacturer requires traceable torque documentation for installation hardware
• AS9100-certified MRO facilities where all torque tools require NIST-traceable calibration documentation
• Airline and fleet operator maintenance programs specifying factory-certified preset tools for repetitive operations
• Production facilities where the preset torque value must be documented for each tool entering the production area

Why source 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. We understand that the 50T-I-SET is a quality management purchase as much as it is a tool purchase — the certificate it ships with is what goes in the tool control file, and that file is what gets reviewed during an FAA surveillance visit or an AS9100 audit. Our on-site ISO 17025-accredited calibration laboratory handles recertification after purchase, issuing a new individually serialized certificate and maintaining the traceability chain your program requires.
