Description
Picture a 1,200 N·m bolt behind a guard rail, with no room to swing a long 3/4″ wrench. The Snap-on MTMB950 torque multiplier handles that kind of joint with a short input stroke. It takes a 1/2″ square input, drives a 3/4″ square output and carries a 950 ft-lb rating, close to 1,288 N·m. Its bar style reaction arm braces against a nearby stop while you pull.
Short space, high load
A hand wrench builds torque through length, so big values need long handles. A gearbox builds it through gearing instead. As a result, the MTMB950 lets a technician reach high values with a compact 1/2″ click wrench and a modest pull. That matters in machine pits, pump rooms and engine bays where a long handle cannot travel.
Where the MTMB950 sits in the bar style line
| Model | Input | Output | Rating |
|---|---|---|---|
| MTMB740 | 1/2 in | 3/4 in | 740 ft-lb |
| MTMB950 | 1/2 in | 3/4 in | 950 ft-lb |
| MTMB2200 | 1/2 in | 1 in | 2,200 ft-lb |
| MTMB3300 | 1/2 in | 1 in | 3,300 ft-lb |
The MTMB740 and MTMB950 share the same drives, so one 3/4″ socket set serves both. Pick the MTMB950 when your top joint sits above 740 ft-lb, or when you want margin just under that value.
Factory and depot jobs for the Snap-on MTMB950 torque multiplier
- Track and sprocket bolts on mid-size excavators.
- Stamping press and die-set bolts in auto parts plants.
- Pump, motor and gearbox base bolts in water and power plants.
- Bogie and coupler bolts during rail depot maintenance.
From target value to input setting
Find the MTMB950 ratio and any correction factor in its manual first. Then divide the target torque by that effective ratio. The answer becomes your input wrench setting. It also helps to keep a printed conversion table with the tool, so each operator uses the same numbers. Finally, pull smoothly and stop at the input wrench signal.
Looking after gears and bar
Clean the output square of the Snap-on MTMB950 torque multiplier after every job, and check it for wear. Never drive the input with an impact wrench, and never use the unit to free seized nuts. Store it dry and inside its case. Also schedule an outside calibration check for the multiplier and its input wrench as a pair.

MTMB950 questions from maintenance planners
Why choose the MTMB950 over a 3/4 in torque wrench?
Choose it when space is tight or the spec runs above a hand wrench range. The MTMB950 needs only a short pull on a 1/2″ input wrench.
What output drive does it have?
A 3/4″ square output, so the MTMB950 takes standard 3/4″ drive sockets.
Is it enough for a 1,000 ft-lb joint?
No. The MTMB950 rating stops at 950 ft-lb. For larger joints, look at the MTMB2200 or a higher-rated model.
