CDI 1002MFRPH – 3/8" Comfort-Grip Torque Wrench

The CDI 1002MFRPH is a 3/8-inch drive, dual-scale micrometer click-type torque wrench covering 10–100 ft-lb (13.6–135.6 Nm) — mechanically identical to the 1002MFRMH in range, accuracy, certification, and dimensions, with one deliberate difference: an ergonomic comfort-grip polymer handle instead of the knurled metal grip. That single change makes it the right version for specific environments and specific workflows.

When the comfort-grip variant is the better choice

The polymer handle was designed for high-repetition work. Mechanics performing back-to-back aircraft in a busy inspection shop, production environments, or extended maintenance events — an annual inspection campaign, a fleet service event — grip a torque wrench dozens or hundreds of times per shift. On bare knurled metal, that repetition translates directly to hand fatigue. The polymer grip distributes contact pressure across a larger surface area and provides thermal insulation that makes a genuine difference in cold hangars and outdoor ramp environments where a metal handle in winter is actively unpleasant to hold for hours.

When the metal handle (1002MFRMH) is the better choice

The knurled metal handle grips better in oily or wet conditions where polymer surfaces become slippery, and bare metal is more resistant to chemical degradation from hydraulic fluid, avgas, and common shop solvents over extended service life. Shops doing engine overhaul or fuel system work where the wrench regularly contacts fluids often prefer the 1002MFRMH. Both wrenches carry the same internal mechanism, the same ±4% CW accuracy, and the same NIST-traceable documentation — the difference is the grip surface, not the tool's capability.

Documentation-ready for certificated maintenance

Every 1002MFRPH ships individually serialized with a NIST-traceable certificate of calibration, satisfying traceability requirements in FAA-accepted maintenance programs, Part 145 repair station QCMs, and ISO 9001 quality systems. Meets or exceeds ASME B107.14 and ISO 6789. Accuracy: ±4% CW, ±6% CCW of indicated value from 20–100% of full scale.

Identical specs to the 1002MFRMH, different grip

• Same 3/8" drive, 10–100 ft-lb (13.6–135.6 Nm) range, 1 ft-lb graduation as the 1002MFRMH
• Same 16" overall length and 2.50 lb weight — same tool footprint in the kit
• Ergonomic comfort-grip polymer handle reduces fatigue on high-repetition inspection and service work
• Thermal insulation from polymer grip matters in cold hangar and ramp environments
• Spring-loaded pull-down lock ring locks the setting positively between fasteners
• Laser-marked dual scale reads ft-lb and Nm simultaneously — no conversion chart needed
• Fixed ratcheting 3/8" drive head with quick-release button
• Audible click plus tactile impulse confirms torque in noisy hangar environments
• Rated to a minimum of 5,000 operating cycles
• Made in the USA by CDI Torque Products, a Snap-on Industrial Brands company

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

• General airframe structural fasteners — AN bolts, NAS hardware throughout the airframe
• Engine accessory mounting hardware and gearbox cover fasteners
• Landing gear components and wheel axle nuts on light GA aircraft
• Ground support equipment wheel, axle, and chassis hardware
• Propeller blade retention bolts on many light aircraft platforms

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 shop prefers metal or comfort-grip handles, both CDI variants ship from the same aviation-specialist source with the same NIST-traceable documentation — and both can be recertified by our on-site ISO 17025-accredited calibration laboratory when they come due.
