Description
The Snap-on 342-41-2 socket adaptor joins two male 3/8 in square drives on one straight axis. Its two female ends let a 3/8 in torque wrench meet a 3/8 in tester or transducer drive. Snap-on lists it in the accessory table of its torque tester section in CAT1500i.
Two male 3/8 in drives, one straight line
Both ends of the 342-41-2 take a male 3/8 in square. So the adaptor bridges two male drives of equal size. For example, it couples a 3/8 in wrench to a 3/8 in transducer with no stepped piece. Because the parts stay inline, the setup adds no offset arm. That keeps a daily wrench check simple and repeatable.
Its neighbors in Snap-on’s adaptor table
| Part | CAT1500i description |
|---|---|
| 342-41-2 | Female 3/8 in square x 3/8 in square socket adaptor |
| 65-26-2 | Female 1/2 in square x 3/8 in square socket adaptor |
| 2000-152-3 | 1/2 in male x 3/8 in female square drive reducer |
So the 342-41-2 is the same-size option in the 3/8 in group. Pick a stepped part only when the wrench and tester differ. Then keep the load within the smaller drive.
3/8 in testers and the Snap-on 342-41-2 socket adaptor
Snap-on lists two 3/8 in drive transducers for its TTC systems: the TTC7 at 30-400 in-lb and the TTC8 at 80-1,000 in-lb. Snap-on also states that every TTC transducer includes the correct adaptor for its range. So a loose 342-41-2 suits a spare kit, a second test station or a fixture you build yourself. On the other hand, the TCR175 comparator checks 3/8 in wrenches through an A2A or GAF2A adaptor, so skip the 342-41-2 for that job.
Keeping the 342-41-2 test-ready
A worn opening lets the square rock, and that play can scatter readings. Therefore, inspect both ends before each session and retire a loose adaptor. Also store it in the tester case with the other drive parts. Snap-on adds that periodic recalibration checks keep tester accuracy, so log the adaptor with the station it serves.
Getting the Snap-on 342-41-2 socket adaptor from Lost in HCM
SMK Vietnam lists this adaptor, while Lost in HCM supplies it and prepares the quote. Tell them the tester or transducer model and the wrench drives you check. Then put your 342-41-2 request to Lost in HCM. You can also browse torque testers and calibration systems, see more torque wrench heads and adaptors, or contact SMK Vietnam.
What testers ask about the 3/8 in female adaptor
Are both ends of the 342-41-2 female?
Yes. Snap-on describes it as female 3/8 in square x 3/8 in square, so both ends are female.
Which Snap-on transducers use a 3/8 in drive?
The TTC7 (30-400 in-lb) and the TTC8 (80-1,000 in-lb).
Can the 342-41-2 link a 3/8 in wrench to a TCR175?
No. Snap-on names the A2A or GAF2A adaptor for that comparator.
