Description
A maintenance crew rarely knows which fastener the next job will bring. So a wrench that changes heads earns a place in the kit. The Snap-on CTECHAN135A torque wrench is a ControlTech ISO wrench with a 9 x 12 receiver and a 135 N·m capacity.

One receiver, shared heads
The CTECHAN135A uses the same 9 x 12 receiver size as the smaller CTECHAN30A. As a result, a team that owns both can share one set of heads between them. That cuts cost and keeps the tool board simple. However, check that each head can carry the torque you apply with the larger wrench.
Sizing up 135 N·m on the Snap-on CTECHAN135A torque wrench
135 N·m works out to about 100 ft-lb. Therefore this wrench covers a broad middle band of industrial bolting. Try to keep your common targets well inside that capacity, rather than right at it. If your work runs much higher, the CTECHBN340A with a 14 x 18 mm receiver is the next step up.
Typical jobs for the CTECHAN135A
- Engine mount, bracket and suspension bolts on cars and light trucks.
- Motor base and coupling bolts in plant maintenance.
- Hydraulic fittings on forklifts, presses and molding machines.
- Busbar and cable lug joints in electrical panels.
With the right head, one handle moves between all of these jobs.
Working with long or offset heads
Some heads add length in front of the receiver. This shifts the point where the force acts, so the wrench may need a setting correction. Ask Lost in HCM whether a correction applies to the heads you choose.
Daily habits that protect accuracy
Pull smoothly at a right angle to the handle. Also never use the wrench to loosen seized bolts. In addition, wipe the receiver clean before you fit a head. Then log each calibration date, so the CTECHAN135A never slips past its due date.
