CDI 1002MFRMH – 3/8" Micrometer Torque Wrench 10-100 ft-lb

The CDI 1002MFRMH is a 3/8-inch drive, dual-scale micrometer click-type torque wrench engineered for the precision demands of aviation maintenance, MRO shops, and professional A&P mechanics. With a 10–100 ft-lb (16.9–132.2 Nm) range and 0.5 ft-lb micro-adjustable graduation, it covers the fastener torque specifications most commonly found in general aviation airframe work, engine accessory installation, and ground support equipment service — the exact applications Pilot John International has served for over two decades.

Documentation that satisfies aviation maintenance requirements

Torque traceability is not optional in certificated maintenance. The 1002MFRMH ships with an individual serial number and a matching certificate of calibration traceable to the National Institute of Standards and Technology (NIST), satisfying the traceability requirements of FAA-accepted maintenance programs, Part 145 repair stations, and ISO 9001 quality systems. The wrench meets or exceeds ASME B107.14 and ISO 6789 — the governing standards for hand torque tools in professional and aerospace applications. When an auditor asks about your torque tool documentation, this wrench has an answer.

Built for shop durability, not the tool aisle

• Knurled metal handle withstands sustained professional use — not the lightweight composite found on consumer alternatives
• Spring-loaded pull-down lock ring locks your torque setting against drift during application
• Laser-marked dual scale reads ft-lb and Nm simultaneously — no unit conversion required
• Fixed ratcheting head with quick-release button allows fast socket changes in confined airframe access panels
• Audible click plus tactile impulse provides positive torque confirmation in noisy hangar environments
• Rated to a minimum of 5,000 operating cycles for long service life under daily shop use
• Made in the USA by CDI Torque Products, a Snap-on Industrial Brands company with 50+ years of precision torque manufacturing

Accuracy and compliance

Accuracy is rated at ±4% clockwise and ±6% counter-clockwise of indicated value from 20% to 100% of full scale — consistent with the tolerance ranges cited in aircraft maintenance manuals for general structural fasteners. The dual-direction calibration means the 1002MFRMH is usable in both installation and removal applications where documented torque values are required.

Typical aviation applications in the 10–100 ft-lb range

• General airframe structural fasteners (AN bolts, NAS hardware)
• Engine accessory mounting hardware and gearbox covers
• Landing gear components and wheel axle nuts on light GA aircraft
• Ground support equipment (GSE) wheel and axle hardware
• Propeller blade retention bolts on many light aircraft
• Avionics rack mounting hardware

Why buy from Pilot John International

Pilot John International is an aviation-specialist distributor — not a general industrial catalog house. We serve Part 145 repair stations, FBOs, flight schools, and MRO operations across the United States. Unlike mega-retailers who sell this wrench alongside garden hoses and power tools, we understand the documentation chain behind every tool we sell. Our on-site ISO 17025-accredited calibration laboratory provides NIST-traceable calibration services, meaning if your 1002MFRMH needs recertification after purchase, you can send it back to us — the same source where your aviation tooling relationship started.
