Description
Hospitals across Vietnam keep adding CT scanners, X-ray rooms and cath labs. Each install bolts heavy gear to floors, ceilings and support frames. The Snap-on TESI75C Torqometer gives field engineers and hospital biomedical teams a simple way to tighten and recheck those bolts in newton meters. It is a Basic model with one needle, and its listing adds a calibration certificate.

A one-needle dial for clinical sites
Hospital work runs on tight windows, often at night or on weekends. So the tool must be quick to read and hard to misuse. A Basic Torqometer has one needle that shows the torque achieved, with no lamp or second pointer. As a result, there is little to set up, and the TESI75C reads the same way for every engineer.
Install and service tasks for the TESI75C
- Floor anchor bolts on CT gantries and patient tables.
- Ceiling rail and tube support bolts in X-ray rooms.
- Mounting bolts on C-arm stands and monitor booms.
- Frame bolts on injector stands and equipment carts.
Always take values from the vendor’s install manual. Also check whether a joint needs thread locker or a fresh bolt.
Keep the Snap-on TESI75C Torqometer out of MRI rooms
This wrench has a steel body, and Snap-on uses an alloy steel torsion bar inside. Therefore it must never cross into an MRI magnet zone, where steel tools can become dangerous. For MRI work, follow the site’s own MR-safe tool rules instead.

Snap-on states that a C added to a stock number orders the certificate of calibration model, hence TESI75C. Lost in HCM files it under Newton Meter Reading/Standard 2% Accuracy. Snap-on applies that grade from 20% of full scale up, so here the band starts at 15 N·m.
Clean handling for the Snap-on TESI75C Torqometer
Wipe the wrench with a dry cloth after each job, then store it in its case outside clinical areas. Also follow the hospital’s cleaning rules for tools that enter patient rooms. Never use it to free a stuck bolt. Then keep the calibration certificate with the install file, and plan recalibration before it lapses.
Request the TESI75C
Imaging vendors and hospital engineering teams can source the Snap-on TESI75C Torqometer from Lost in HCM, which partners with SMK Vietnam. To budget for your next install, request a quote from Lost in HCM. Other torque wrenches sit in the SMK catalog, Snap-on details live at snapon.com, and you can contact SMK Vietnam any time.
Imaging install FAQ
Is the TESI75C safe near an MRI magnet?
No. It is a steel tool, so keep it outside the MRI zone at all times.
Why choose a Basic dial over a signal model?
A single needle has fewer parts to set or fail. Signal models add a lamp, which this one lacks.
Does it come with paperwork?
Yes. Its listing title names a calibration certificate. Ask Lost in HCM for a sample.
