Description
Many tool cribs check 3/8 in click wrenches on a tester built around a 1/2 in drive. The Snap-on 2000-152-3 drive reducer makes that link. Its 1/2 in male end fits the tester side, and its 3/8 in female end takes the wrench. So the smaller wrench seats square and the load runs straight down the axis.
Smallest step in the Snap-on reducer set
Snap-on lists four square drive reducers with its torque tester accessories. This 1/2 by 3/8 in part is the smallest. The 2000-226-3 steps 3/4 to 1/2 in, and the 2000-226-2 steps 1 to 3/4 in. Then the 2000-0154-18 goes from 1-1/4 to 3/4 in for heavy transducers. Therefore, a lab that checks 3/8 in wrenches most of the day reaches for the 2000-152-3 first.
Reducer or socket adaptor?
The same table also lists female-to-female socket adaptors. For example, the 65-26-2 has a female 1/2 in square and a female 3/8 in square. So the right part depends on the drive your tester presents. If the tester side needs a male square, pick the Snap-on 2000-152-3 drive reducer. If it needs a female square, look at the socket adaptor instead.
Benches that may already cover 3/8 in
Snap-on’s TCR175 comparator has a 1/2 in female square input. For 3/8 in wrenches, Snap-on names the A2A or GAF2A adaptor for that unit. Likewise, the QCDTC3250 digital checker ships with a GAF2A adaptor. So check what sits in your drawer before you order. Still, a spare 2000-152-3 helps when two people test at once.
Keeping the Snap-on 2000-152-3 drive reducer true
Wipe both squares before each session, because grit stops the wrench from seating fully. Also check the corners for rounding after heavy use. In addition, keep the reducer with the tester, so nobody borrows it for shop work. Finally, Snap-on reminds users that testers need periodic recalibration checks to stay accurate.

2000-152-3 reducer questions
Which end takes the 3/8 in wrench?
The female end. The 1/2 in male end goes into the tester, transducer or adaptor.
I already own a GAF2A. Do I still need this reducer?
Maybe not. Snap-on names the A2A or GAF2A adaptor for 3/8 in wrenches on its TCR175 comparator, so check your bench first.
Is it the smallest Snap-on reducer?
Yes. It is the 1/2 to 3/8 in step; the others go up to 1-1/4 to 3/4 in.
