Description
Most maintenance carts already hold a full set of 3/8″ sockets and extensions. So a low-torque tool with a 1/4″ drive often ends up on an adapter. The Snap-on CTECH2MR100 torque wrench avoids that step. It delivers 5-100 in-lb through a 3/8″ ratchet head, with the full ControlTech Micro electronics behind it.
Why pick a 3/8 inch drive for such low torque
Every adapter adds length and a little play to the joint. In addition, a stack of adapters can tip on a small screw head. With the CTECH2MR100, your existing 3/8″ sockets fit straight on. However, 1/4″ sockets are slimmer, so the CTECH1MR100 may still win in very tight pockets.
Lights, beep and vibration instead of a click
Snap-on points out that a user can overshoot a click wrench by as much as 20%, because the pull continues after the click. The CTECH2MR100 warns earlier. Yellow, green and red LEDs show approach, target and over-torque, while a beep and handle vibration back them up. As a result, operators stop on time even with gloves on or in a loud shop.

Common questions on the CTECH2MR100
What separates the CTECH2MR100 from the CTECH1MR100?
The drive size. Snap-on lists both at 5-100 in-lb with a 72-tooth head, 0.9 lb and 10.9 inches. This one has a 3/8″ drive.
Will it measure counterclockwise torque?
Yes. Snap-on quotes ±3% counterclockwise from 20% to 100% of full scale, so it suits left-hand threads.
Which battery does it take?
One AA lithium cell, which Snap-on rates at about 40 hours of continuous use. It also accepts alkaline or NiMH cells, which are not included.
