U.S./ Metric Basic Stubby Torque Driver (with Chart) – TQSSC2.5FUAC

The dial torque screwdriver TQSSC2.5FUAC belongs to the Snap-on TORQOMETER® 1/4 inch drive torque drivers range, and Lost in HCM supplies it to workshops and factories across Vietnam. Snap-on lists the country of origin as USA. The storage case is PB47.

Dial torque screwdriver TQSSC2.5FUAC overview

The dial torque screwdriver TQSSC2.5FUAC shows low torque on a dial while you turn a small screw or nut. You do not need to preset a value first. Instead, you watch the needle and stop at the spec, so the reading stays in plain view.

Snap-on builds these TORQOMETER® drivers in the USA with dual scales in kg·cm and in-lb. Ranges in this list run from 15 in-lb up to 75 in-lb. Meanwhile, stubby and standard lengths suit tight spaces and open benches.

The asme®/ansi® is B107.14.2004. The model is Stubby Follow-up. The dial is US/Metric Reading.

The length is 5-1/4 inches. The increments is 1.000 kg•cm/1.0 in-lb. The range is 35 kg•cm/30 in-lb.

Specifications at a glance

The table below follows the Snap-on data for TQSSC2.5FUAC. In addition, we converted imperial torque values to N·m where Snap-on lists none.

How the dial torque screwdriver works

The Follow-up design adds a second needle that sits beside the main one. First, the main needle pushes the memory needle as torque rises. Next, the main needle drops back when you release, while the memory needle stays at the peak.

This lets an inspector read the highest value after the turn, even if the operator could not see the dial. Then the operator resets the memory needle by hand before the next screw. For this reason, Follow-up drivers suit audits and first article checks.

Key features of the dial torque screwdriver TQSSC2.5FUAC

Every driver in this family shares the same dial design, from the twisting shaft to the memory needle. Here are the features that matter most when you compare options for small fasteners.

• Dual kg·cm and in-lb dial. The dial reads in both kg·cm and in-lb on one face. So operators can follow Japanese, Korean, or US drawings without a separate conversion chart at the bench.
• Memory needle for peak. Every model in this list is a Follow-up driver with a memory needle. As a result, the peak value stays on the dial after the turn, which makes records easy.
• 2% accuracy in both directions. Snap-on rates these drivers within 2% of reading from 20% of full scale to full scale. That applies clockwise and counterclockwise, so loosening checks are just as reliable.
• Stubby and standard lengths. Stubby models measure about 5-1/4 inches, while standard models run a few inches longer. Therefore, you can reach screws inside tight housings or work comfortably on an open bench.
• Low ranges for small fasteners. Ranges in this list run from 15 in-lb to 75 in-lb, with fine increments. This suits terminal screws, small covers, and sensors where a small overshoot can strip threads.
• 1/4 inch square drive. Each driver uses a 1/4 inch square drive that accepts bit holders and small sockets. In addition, some models include an internal 1/4 inch square drive in the handle.

Snap-on data sheet notes

Snap-on also lists these details for TQSSC2.5FUAC:

• Guaranteed Accuracy: Within ± 2% of the reading from 20% of full scale to full scale clockwise and counterclockwise.

Typical applications

A dial driver earns its place where a small screw needs a known value and a clear record. The tasks below are the most common uses we see from buyers in Vietnam.

• Electronics enclosure screws. Phone, PC, and control box housings use small screws in soft plastic bosses. A dial driver shows the exact value, so operators stop before the thread strips.
• Terminal and connector screws. Electrical terminals need enough torque for good contact but not so much that they crack. Therefore, panel builders use dial drivers to confirm each terminal value during checks.
• Audit checks on small joints. Inspectors turn a finished screw slowly and read the peak on the memory needle. This shows whether automatic screwdrivers on the line are still holding their set value.
• Sensor and instrument mounting. Sensors, gauges, and optical parts often need very low torque to avoid stress. In addition, the dial lets technicians see small values that a click driver would not show.
• Small engine and motorbike parts. Carburetor screws, small covers, and electrical parts on motorbikes need light, even torque. The stubby models also fit into tight spots around the engine and frame.
• Lab testing and training. Quality labs use dial drivers to test screw samples and show trainees how torque builds. Meanwhile, the memory needle lets staff read and log each result after the test.

Industries that use the dial torque screwdriver TQSSC2.5FUAC

Any sector that builds or audits small assemblies can use a dial driver. So these tools show up in electronics, panels, vehicles, and labs. Here is how each industry uses them in practice.

• Electronics manufacturing. Electronics plants in Bac Ninh, Bac Giang, and Thai Nguyen tighten thousands of small screws per shift. Dial drivers help quality teams audit these joints and confirm power screwdriver settings.
• Electrical panel building. Panel and switchgear makers torque terminal screws to the values on each drawing. So FDI suppliers in Vietnam use dial drivers to check and record these values for customers.
• Automotive and motorbike. Car and motorbike plants assemble lamps, sensors, and small modules with light screws. Therefore, line auditors use dial drivers to verify each station against its work instruction.
• Medical device assembly. Medical device plants in Vietnam's industrial parks build parts with tight torque limits. A memory needle also gives operators a clear peak value for their batch records.
• Aviation maintenance. Aircraft panels, avionics, and fittings use small fasteners with listed torque values. Meanwhile, MRO teams at Vietnamese airports need dial tools that read in both directions.
• Quality and test labs. Factory labs test screws, inserts, and plastic bosses against design specs. Dial drivers give them a direct reading, and the warranty covers calibration at a Snap-on Repair Center.

Dial torque screwdriver TQSSC2.5FUAC compared with similar brands

Before you buy, it helps to see how the dial torque screwdriver TQSSC2.5FUAC compares with other torque screwdrivers. However, range alone does not decide the choice. Instead, look at the reading style, the units on the scale, and how your team records results.

Choose a dial driver for audits and changing specs, and a preset driver for fixed values on the line. For this reason, many plants keep both types on hand. Meanwhile, check scale units and standards, and 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 where your usual spec falls between 20% and 100% of full scale. Snap-on rates the accuracy in that band, so values below it are less reliable.
• Choose stubby models for tight housings and standard models for open benches. Also, the longer body also gives a steadier grip when you turn slowly.
• Check the torque units on your drawings first. These drivers read both kg·cm and in-lb, so convert N·m specs carefully before you start a new job.
• Next, think about how your team keeps records. Because every model here has a memory needle, an inspector can read and log the peak after each turn without watching closely.
• Plan bits and sockets for the 1/4 inch square drive. In addition, check whether your chosen model has the internal square drive in the handle.
• Order a spare driver if one tool serves a whole line. Then the line keeps running while the other driver is away for its recalibration.

Care, storage and calibration

• Store the driver in its case with the dial facing up, away from heavy tools. That way, the dial glass and the needles stay safe from knocks and drops.
• Wipe the handle and dial with a dry cloth after each shift. Also keep solvents and cleaning sprays off the dial face, because they can cloud the glass.
• Have the driver calibrated every 12 months or 5,000 cycles, as ISO 6789-1:2017 recommends. We can arrange recalibration through an accredited laboratory or a Snap-on Repair Center.
• Never turn past the top of the scale or use the driver to break loose seized screws. Overload can damage the shaft, so have the tool checked after any shock.
• Pack the driver in its case for transport between sites. In addition, keep it dry during the humid season so the square drive and gears stay free of rust.
