Description
A torque ratio of 125 to 1 changes what one person can do with an ordinary wrench. The Snap-on MTMP14700 torque multiplier uses that ratio to reach 14,700 ft-lb, or 20,000 N·m, from a 1/2 in input. It is a plate style manual unit, so it needs no air, hydraulics or mains power on site.
Catalog figures for the MTMP14700
| Item | Value |
|---|---|
| Torque ratio | 125:1 |
| Output range | 1,470-14,700 ft-lb (2,000-20,000 N·m) |
| Input drive | 1/2 in female square |
| Output drive | 2-1/2 in male square |
| Reaction | Plate |
| Anti wind-up ratchet | Fitted as standard |
These values come from the Snap-on Industrial catalog. Confirm them against the data plate when the tool arrives.
From target torque to wrench setting
Divide the joint value by the MTMP14700 torque ratio. For example, a 12,000 ft-lb target needs about 96 ft-lb at the input. So a common 1/2 in click wrench can drive the full load. Even so, follow any correction chart that Snap-on supplies with your unit. Also choose an input wrench that reaches the setting near the middle of its scale, because that gives better repeatability.
Why the anti wind-up ratchet matters
At high ratios, the gear train winds up like a spring as load builds. Without a holding ratchet, that stored energy would kick the input wrench back between strokes. On the MTMP14700, the anti wind-up ratchet keeps the gearbox loaded instead. As a result, the operator can reset the wrench safely and keep turning.
Planning a job with the Snap-on MTMP14700 torque multiplier
- Sockets: the 2-1/2 in output drive needs matching heavy-duty sockets, so order them early.
- Reaction: find a solid point, such as an adjacent nut, for the plate to bear on.
- Access: high-ratio units turn slowly, so allow time for many input strokes.
- Handling: a tool of this class is heavy, so plan a lifting aid if the joint sits overhead.
Typical joints in this range
Large slewing rings, mill heads, press tie rods, ship propulsion parts and hydro gate bolts can fall in this band. However, check each value first, because joints below 2,000 N·m sit under the bottom of the output range.
Choosing between the plate style sizes
Snap-on lists four plate style units. The MTMP7000 tops out at 9,500 N·m, while the MTMP25000 reaches 34,000 N·m with a 3/4 in input. Therefore the Snap-on MTMP14700 torque multiplier fits the middle ground, where joints sit between roughly 10,000 and 20,000 N·m.
Care after each job
After each MTMP14700 job, wipe the drive squares and reaction plate clean, and look for cracks or rounding. Never use the unit to break fasteners loose. In addition, Snap-on notes that periodic recalibration keeps the output accurate, so add it to your tool schedule.

MTMP14700 questions
What input wrench does the MTMP14700 need?
Use a 1/2 in drive torque wrench. At 125:1, about 118 ft-lb at the input gives the rated maximum.
What socket fits the output?
The output is a 2-1/2 in male square, so you need 2-1/2 in drive sockets.
Is 2,000 N·m too low for it?
That is the bottom of its listed range. For smaller joints, a lower-ratio unit gives better control.
