Description
Part numbers often tell you more than product titles do, and the Snap-on CTECH1R240A torque wrench proves the point. Some listings call it a flex-head tool. However, Snap-on’s own catalog shows a fixed ratcheting head on a 1/4 inch square drive, while the flex version carries a different code. So this page follows the catalog.
R or FR: decoding the CTECH1R240A part number
In the ControlTech Industrial line, the FR models carry a sealed flex head, while the R models keep a fixed ratcheting head. Thus the CTECH1R240A has a rigid neck, and the CTECH1FR240A pivots. Both share the 1-20 ft-lb range, the 72-tooth gear and the 14.1 inch length. Choose the fixed head when you want a stiff, predictable feel on open joints. On the other hand, pick the flex head when the handle must clear an obstacle.
Why an all-steel body on a 20 ft-lb tool
Snap-on builds the CTECH wrenches with an all-steel body for strength. As a result, the CTECH1R240A weighs 2.0 lb, against 1.2 lb for the aluminum CTECHL1R240A. That extra mass pays off in a shared tool crib, where wrenches pass between shifts and sometimes hit the floor. In contrast, an operator who keeps one wrench at a fixed station may prefer the lighter model.

Keeping the CTECH1R240A in service
First, fit fresh AAA lithium cells before a long run, because a flat wrench stops the line. Next, keep the ratchet clean, and use the RKRT72A kit when it needs a rebuild. Also, never pull past 20 ft-lb, since Snap-on warns against going over rated torque. Finally, watch the calibration due indicator on the CTECH1R240A, and book a recheck with your calibration provider when it shows.
