Description
Many Japanese-owned plants in Vietnam still give small screw and bolt specs in kg·cm. The Snap-on TEC12A Torqometer shows that unit on its dial, next to in-lb, so a technician reads either value straight off the face. It is a compact Basic model with one needle and a 3/8-inch drive. As a result, it fits bench work on light assemblies.
Why a kg·cm scale saves time
Converting units on the line adds a step, and every step invites a slip. For example, a spec of 120 kg·cm comes to about 104 in-lb, which few people work out in their head. With the TEC12A, the operator simply watches the metric scale instead. In addition, the US scale serves any drawing from an American customer.
Snap-on TEC12A Torqometer, line by line
- Square drive: 3/8 inch.
- Metric scale: 175 kg·cm full scale, in 5 kg·cm steps.
- US scale: 150 in-lb full scale, in 5 in-lb steps.
- Body length: 9-29/32 in (252 mm).
- Width and head depth: 2-11/16 inches and 1-1/4 inches.
- Case: PB9 storage case.
Snap-on prints these values in the Combination US/Metric Reading/Standard 2% Accuracy table of its CAT1500i catalog. At full scale, either side equals roughly 17 N·m.
Light joints that fit the TEC12A
This range fits small fasteners where a heavy wrench would overshoot. Typical jobs include motor end-bell screws, sensor brackets, fan mounts and terminal screws on control gear. The TEC12A also suits checks on fixture and jig bolts in electronics and camera assembly. However, always use the drawing value and the joint method that the customer gives.
Keep readings in the 2% band
Snap-on’s torque brochure defines the Standard grade as within 2% of reading from 20% of full scale to full scale. So the TEC12A works best from about 35 kg·cm or 30 in-lb upward. For lighter screws, a 1/4-inch model with a smaller scale fits better. Also read the dial square on, because a side view shifts the needle against the marks.
Bench care for a small TEC12A
A small dial wrench takes knocks when it slides off a bench. Therefore store the Snap-on TEC12A Torqometer in its PB9 case between shifts. Check that the needle sits at zero before each batch. Never push past 150 in-lb, and never use it to free a stuck screw. Plan an outside lab check at the interval your quality system sets.

Questions about the Snap-on TEC12A Torqometer
Is 175 kg·cm the same as 17.5 N·m?
Close, but not quite. 175 kg·cm equals about 17.2 N·m, because one kg·cm is about 0.098 N·m.
Does the TEC12A keep its top reading?
No. It is a Basic model with a single needle. If you need a held value, Snap-on lists the TEC12FUA follow-up model in the same catalog row.
