TORQOMETER® U.S./ Metric Basic (with Chart) -TEC175C

The dial torque wrench TEC175C is a Snap-on dial torque wrench that Lost in HCM supplies to workshops and factories across Vietnam. The metric range is 25 kg•m. The width, inches is 2-3/4 (70) mm.

Dial torque wrench TEC175C overview

Many teams need to see torque as it builds, not just hear a click. The dial torque wrench TEC175C shows the reading on a clear dial. So you can watch for a slow climb or a sudden jump. In addition, the second scale gives metric values without a chart.

Each dial pairs a US scale in ft-lb or in-lb with a metric scale in kg·cm or kg·m. Therefore, buyers who work from Japanese or European specs can read kg values straight off the face. Snap-on builds the whole family in the USA.

Snap-on lists the country of origin as USA. The storage case is PBR5. The us range is 175 ft-lb.

The model is Basic. The length is 18-3/4 inches. The square drive is 1/2 inches.

The us increments is 5 ft-lb.

Specifications at a glance

These figures come from the Snap-on listing for TEC175C. Values marked “calculated” are unit conversions we added for convenience.

How the dial torque wrench works

Snap-on offers three ways to read the dial in this family. The Basic model has one needle that returns to zero when you release. By contrast, a Follow-up model adds a second pointer that stays at the peak reading.

Light Signal models add a light cue at a value you set on the dial. That is why they suit noisy shops where you cannot watch the dial closely. In each case, the dual scale lets you read US and metric units at once.

Key features of the dial torque wrench TEC175C

Every model in this family shares the same dial design and dual scale. Here are the features that matter most when you compare TORQOMETER® options for your plant. They also help you match a model to each job.

• Dual US and metric scale. Each dial carries a US scale in ft-lb or in-lb plus a metric scale in kg·cm or kg·m. Therefore, you can work from US, Japanese, or European specs without a conversion chart.
• Live needle reading. The needle moves as torque builds, so you see the value at every point of the pull. As a result, you can spot a stripped thread or a seized bolt before damage spreads.
• Follow-up peak pointer. Follow-up models add a second pointer that stays at the highest reading. So you can read the final value after the pull, even when the dial faces away from you.
• Light Signal option. Light Signal models give a light cue at the value you set on the dial. In addition, this helps in loud or crowded work areas where watching a needle is hard.
• Standard 2% accuracy class. Snap-on lists this family in its standard 2% accuracy class for TORQOMETER® wrenches. That gives quality teams a clear figure to match against their own torque tolerance.
• Wide drive and range spread. Square drives run from 1/4 inch to 1-1/2 inch, while ranges climb from 15 in-lb to 3,000 ft-lb. Because of this, one family covers small fasteners and large flange bolts.

Typical applications

These wrenches solve one problem well: showing torque as it builds on the fastener. Below are typical jobs where that matters, from line audits to large flange bolts. Each one also rewards a clear and steady reading.

• Torque audits on finished joints. Quality inspectors use a dial wrench to check torque on joints that a power tool already tightened. Because the needle shows the full reading, they can log the real value for each audit.
• Production line spot checks. Line leaders check sample fasteners each shift to confirm that tools still hold their set values. For example, a Follow-up model keeps the peak reading so the checker can note it later.
• Engine and gearbox assembly. Head bolts, bearing caps, and gearbox covers need steady torque in several passes. So a live dial helps technicians pull smoothly and stop right at the spec.
• Large flange and base bolts. The big 3/4 inch, 1 inch, and 1-1/2 inch models suit flange, pump, and machine base bolts. In addition, their long handles give the leverage that high ranges need.
• Small electrical fasteners. The in-lb models suit terminal screws, sensor mounts, and panel hardware in control cabinets. Meanwhile, the kg·cm scale matches the units on many Japanese equipment manuals.
• Breakaway and loosening checks. Some teams read the torque needed to start turning a tight fastener. That way, the dial helps them judge whether a joint held its clamp load in service.

Industries that use the dial torque wrench TEC175C

Any sector that audits joints or tightens large bolts can use a dial torque wrench. So these tools show up in assembly plants, power stations, and hangars. Here is how each industry puts them to work.

• Automotive manufacturing. Car and motorbike plants in Vietnam run torque audits on safety joints every shift. Therefore, many FDI quality teams keep dial wrenches beside the line to check and record real values.
• Electronics and electrical. Electronics plants in Bac Ninh and Hai Phong torque small screws on fixtures, panels, and cabinets. The in-lb and kg·cm models suit that work, because their scales read fine values clearly.
• Heavy equipment and machinery. Excavators, cranes, and presses use large bolts on frames, slewing rings, and bases. So service crews across Vietnam use the 1 inch and 1-1/2 inch models for those high-torque joints.
• Energy and power plants. Power plants torque flange bolts on pumps, valves, and turbine casings during each outage. In addition, a dial reading gives crews a clear value to note on the work order.
• Aviation maintenance. MRO teams at Vietnamese airports follow strict torque values from the aircraft maintenance manual. Meanwhile, a dual scale helps when manuals and local specs use different units.
• Metalworking and fabrication. Steel structure and machine builders in Dong Nai and Binh Duong tighten base and frame bolts daily. For example, their QC staff use dial wrenches to confirm torque before shipping a machine.

Dial torque wrench TEC175C compared with similar brands

Before you buy, compare how each dial wrench line reads, holds a peak, and finds local service. However, the dial itself is only one part of the choice. The table below places the dial torque wrench TEC175C next to other well-known dial wrench lines.

Choose the dial style first, then match range, drive size, and units to your joints. Snap-on suits plants that want US and metric on one face. Meanwhile, metric-only plants may weigh other lines, so confirm current specs with each maker. Specifications change over time, so confirm current data with each maker before you decide.

Choosing the right model

• Pick a range that puts your target torque in the upper part of the dial. Readings near the very low end are harder to judge, so leave some margin.
• Choose a Follow-up model when you must read the peak after the pull. It suits audits where the dial faces away from the operator.
• Consider a Light Signal model for loud or crowded areas. Then the operator gets a light cue instead of watching the needle the whole time.
• Match the square drive to the sockets you already own. For example, a 3/4 inch model avoids an adapter on heavy sockets and keeps the reading clean.
• Check which metric unit your specs use before ordering. Some models read kg·cm while larger ones read kg·m, so pick the scale that fits your manuals.
• Plan for handle length on the large models, because some exceed 40 inches. Measure the space around the joint so the operator can pull smoothly.

Care, storage and calibration

• Store the wrench in its Snap-on case with the dial facing up. Also keep it away from heavy tools that could crack the glass or bend the pointer.
• Wipe oil and dust off the dial face and handle after each shift. However, never spray solvent into the dial, because it can reach the gear train.
• Have the wrench calibrated every 12 months or 5,000 cycles, as ISO 6789-1:2017 recommends. We can arrange recalibration through an accredited laboratory.
• Never pull past the top of the scale, and never use the wrench as a breaker bar. Overload can bend the beam, so the needle no longer reads true.
• Pack the wrench in its case for transport between sites. In addition, keep it dry during the humid season so the dial stays clear and free of fog.
