Description
Heavy torque wrenches with a 3/4 in drive still need checking, even when the bench gear has a bigger square. The Snap-on 2000-226-2 drive reducer bridges that step. It carries a 1 in male square on one side and a 3/4 in female square on the other, so a 3/4 in drive can work into 1 in female equipment.

What the 2000-226-2 connects
- Wrench side: the 3/4 in female square accepts a 3/4 in male drive.
- Equipment side: the 1 in male square fits a 1 in female input, socket or fixture.
- Category: Snap-on lists it in the accessories table for its torque comparators.
Lost in HCM files it under electronic torque testers and calibrators as well, so it belongs on the test bench.
The Snap-on square drive reducer family
| Part | Male end | Female end |
|---|---|---|
| 2000-152-3 | 1/2 in | 3/8 in |
| 2000-226-3 | 3/4 in | 1/2 in |
| 2000-226-2 | 1 in | 3/4 in |
| 2000-0154-18 | 1-1/4 in | 3/4 in |
Each part steps down one size, so you can match the reducer to the two squares you actually have.
Choosing the Snap-on 2000-226-2 drive reducer for a bench
First, confirm the square on your tester or transducer mount. Next, confirm the drive on the wrenches you check most often. If the gap is exactly 1 in down to 3/4 in, the Snap-on 2000-226-2 drive reducer closes it on its own. However, if you need a female-to-female link instead, Snap-on offers socket adaptors such as the 75-25-1. Either way, keep the chain short, since every joint adds play between wrench and sensor.
Bench care for the 2000-226-2
Check both squares for burrs and rounding whenever you set up a test. A loose fit can make readings drift from one pull to the next, so replace a worn reducer early. Also keep the squares clean and lightly oiled against rust in humid workshops. Finally, Snap-on advises periodic recalibration checks of the tester itself.

2000-226-2 FAQ
Which end takes my wrench?
The 3/4 in female end takes a 3/4 in male square drive. The 1 in male end then goes into a 1 in female input or socket.
Does Snap-on list a torque rating for the reducer?
Not in the accessories table we checked. Stay within the rating of the tester and the wrench, and ask Lost in HCM about the reducer itself.
Is this a calibration service?
No. It is a hardware adaptor only. SMK Vietnam and Lost in HCM do not calibrate testers or wrenches.
