TORQOMETER® U.S./ New. Met. Basic – TER100

The dial torque wrench TER100 belongs to the Snap-on Torqometer® dual-scale dial torque wrenches range, and Lost in HCM supplies it to workshops and factories across Vietnam. The width, inches is 2-3/4 (70) mm. Snap-on lists the country of origin as USA.

Dial torque wrench TER100 overview

Quality labs and audit teams often need a torque reading, not just a pass signal. The dial torque wrench TER100 meets that need, because its dial shows US units and metric units side by side. So one tool serves both US and metric specs.

The dual scale suits Vietnamese plants that build to Japanese, Korean, European, and US drawings. Meanwhile, the Follow-up model keeps a memory pointer at the peak value. Light Signal models instead add a visual signal for a preset torque, which helps in busy areas.

The storage case is PBR5. The us range is 100 ft-lb. The model is Basic.

The increments is 5 N•m. The length is 16 inches. The head depth is 1-3/8 inches.

The range is 140 N•m.

Specifications at a glance

The table below follows the Snap-on data for TER100. In addition, we converted imperial torque values to N·m where Snap-on lists none.

How the dial torque wrench works

Inside a dial torque wrench, a steel beam bends slightly as you pull on the handle. Then a gear train turns that small bend into pointer travel across the dial. As a result, you read the torque at the pointer tip as the load builds.

First, check that the pointer sits at zero before each job, because an offset adds error. Next, pull smoothly at the handle grip and watch the pointer climb. Finally, stop at the target value and hold the load for a moment.

Key features of the dial torque wrench TER100

The details below explain why these wrenches suit audits and precise assembly. They also show what to check before you add a new model to your tool crib. In short, start with range and model type.

• Guaranteed 1% reading accuracy. Snap-on guarantees accuracy within ±1% of reading from 20% of full scale to full scale. As a result, these wrenches suit audit checks and precise assembly specs.
• Dual US and metric scales. Each dial shows a US scale in in-lb or ft-lb next to a metric scale. So operators can work to US or metric drawings without converting values by hand.
• Three model choices. Basic models show live torque, while Follow-up models hold the peak reading on a memory pointer. In addition, Light Signal models add a visual signal for a preset value.
• Wide torque range. The family runs from 15 in-lb models for small fasteners up to 1,000 ft-lb models. Therefore, one brand and one reading style can cover bench work and heavy equipment.
• Five square drive sizes. Square drives come in 1/4, 3/8, 1/2, 3/4, and 1 inch sizes. So you can match the wrench to the socket size and torque level of the job.
• Reads clockwise and counterclockwise. In addition, the dial reads torque in both directions with the same rated accuracy. For example, you can check a left-hand thread without a separate wrench or an adapter.

Typical applications

These wrenches solve one problem well: showing live torque as a joint tightens. Below are typical jobs where that matters, from audits to heavy bolts. Each one also rewards a steady, smooth pull on the handle.

• Audit checks on finished joints. Inspectors use a dial wrench to measure the torque already in a joint. Because the pointer shows live values, they can note the reading where the fastener starts to turn.
• Engine and gearbox assembly. Engine and gearbox builds need repeatable torque on many bolt sizes. Therefore, a dual-scale dial wrench lets builders follow US or metric manuals with one tool.
• Aircraft maintenance tasks. Aviation manuals often list torque in in-lb for small fittings and hardware. In addition, the Follow-up pointer helps technicians read the value when the dial sits out of view.
• Electrical and bus bar joints. Bus bar bolts and terminal studs need the right clamp force to avoid hot spots. So electricians use low-range models to tighten and verify these joints.
• Heavy equipment and large flanges. The 3/4 and 1 inch drive models reach 600 and 1,000 ft-lb. As a result, crews can torque track bolts, slew rings, and flange bolts with a visible reading.
• Training new technicians. A live dial helps trainees feel how torque builds as a fastener tightens. Then they learn to pull smoothly and stop at the target value before moving to click wrenches.

Industries that use the dial torque wrench TER100

Any sector with critical bolts needs a reading it can trust and document. So dial wrenches show up in plants, hangars, and power sites. Here is how each industry puts them to work every day.

• Automotive manufacturing. Car and motorbike plants run audit stations next to their assembly lines. In Vietnam, FDI makers often need recorded torque values, so dial wrenches suit their quality checks.
• Aviation maintenance. MRO teams at Vietnamese airports work to manuals that list torque in US units. Therefore, a dual-scale dial wrench helps them meet the spec and record the reading.
• Electronics and electrical. Electronics and electrical panel plants in Bac Ninh and Hai Phong torque small screws and terminal studs. Therefore, low-range models in in-lb and metric units suit these light, precise joints.
• Heavy equipment. Mining and construction fleets use large bolts on tracks, frames, and slew rings. So contractors in Vietnam rely on 3/4 and 1 inch drive models for these high-torque joints.
• Energy and power. Power plants and wind farms tighten flange, pump, and turbine bolts to strict values. In addition, crews in Vietnam's growing wind sector need tools that show the actual reading.
• Quality control labs. Factory quality labs check incoming parts and finished joints against drawings. Meanwhile, audit teams in Binh Duong and Dong Nai plants use dial wrenches to document breakaway torque.

Dial torque wrench TER100 compared with similar brands

Dial torque wrenches are less common today, yet several makers still offer them. The table compares the dial torque wrench TER100 with common dial and electronic options. However, each choice suits a different mix of budget, reading style, and service needs.

If your team wants a live mechanical reading in two unit systems, the Torqometer line fits well. It also holds ±1% of reading in both directions. Even so, confirm current specs with each maker before you compare models side by side. 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 between 20% and 100% of full scale. Otherwise, below 20%, the ±1% accuracy rating does not apply.
• Choose the Basic model for live readings and the Follow-up model when you must read after the pull. For example, Follow-up suits blind or awkward joints.
• Match the square drive to your sockets and torque level. A 1/4 inch drive suits small in-lb work, while 3/4 and 1 inch drives handle heavy bolts.
• Order a certificate version when your quality system needs a record from day one. Those versions ship with a calibration certificate, which helps during your first audit.
• Check the wrench length against the space around the joint. For example, lengths run from about 10 inches on small models to almost 67 inches on the 1,000 ft-lb model.
• Check the storage case listed for your model, such as PB9, PB39, or PBR5. A proper case protects the dial lens and mechanism during transport.

Care, storage and calibration

• Store the wrench in its case with no load on it, away from heat and direct sun. Then the dial, lens, and beam stay protected between jobs.
• Wipe off oil, grease, and dust with a dry cloth after use. Also keep solvents away from the dial face, because they can cloud the lens.
• Send the wrench for calibration every 12 months or 5,000 cycles, as ISO 6789-1:2017 recommends. We can arrange recalibration through an accredited laboratory.
• Never pull past full scale or use the wrench to break loose seized bolts. An overload can bend the beam, so check the zero before the next use.
• Carry the wrench in its case between sites and avoid dropping it. In addition, keep it dry during the rainy season to protect the mechanism.
