U.S./ Metric Follow-up Torque Driver – TQSC1FUA

The dial torque screwdriver TQSC1FUA 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 TQSC1FUA overview

The dial torque screwdriver TQSC1FUA 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 Standard Follow-up. The dial is US/Metric Reading.

The length is 7-3/4 inches. The increments is .5 kg•cm/.5 in-lb. The range is 17 kg•cm/15 in-lb.

Specifications at a glance

The table below follows the Snap-on data for TQSC1FUA. In addition, we converted imperial torque values to N·m where Snap-on lists none.

How the dial torque screwdriver works

Inside a dial torque screwdriver, a slim shaft twists a tiny amount as you turn the handle. A gear set turns that twist into needle travel across the dial. Therefore, the needle position matches the torque at the square drive.

Because the shaft springs back after each turn, the main needle returns to zero. That means there is no spring to unload after use. However, you should still check that the needle rests at zero before each job.

Key features of the dial torque screwdriver TQSC1FUA

The details below explain why these drivers suit audits and fine work on small screws. They also show what to check before you choose a range, a length, and a drive setup.

• 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.

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 TQSC1FUA

Dial torque drivers matter wherever small screws must reach a known, low torque. The industries below use them every day. Many of these teams also work in FDI plants across the industrial parks of Vietnam.

• 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 TQSC1FUA compared with similar brands

Several makers sell low-range torque drivers, from dial types to preset click types. Each design suits a different style of work. The comparison below shows where the dial torque screwdriver TQSC1FUA fits among common choices for small fasteners.

If your team needs to see and record small torque values, a dial driver with a memory needle is a strong choice. Preset drivers suit fast repeat work instead. Even so, confirm current specs with each maker before you compare. 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.
