Tranducer Mount (5-50 in-oz to 80-1,000 in-lb) – TTC3421

The torque tester accessory TTC3421 belongs to the Snap-on Versatest® torque tester accessories range, and Lost in HCM supplies it to workshops and factories across Vietnam. Snap-on lists its working range as 5-50 in-oz to 80-1,000 in-lb. Snap-on lists the country of origin as USA.

Torque tester accessory TTC3421 overview

Plants that test many torque tools need fast changeovers and clean records. The torque tester accessory TTC3421 supports both, because it fits the Versatest® system the team already runs. In short, you add a capability without buying a new tester.

The PC cable links the TTC610 digital indicator to a computer, so readings can move into a file. Also, the screwdriver testing kit adapts the loader system for torque screwdrivers. Lost in HCM supplies these parts to FDI plants with CO/CQ papers and a VAT e-invoice.

How the torque tester accessory works

Each accessory adds one link in that chain. The transducer mounts hold the sensor square and steady, so side loads do not upset the reading. Then the screwdriver testing kit lets the loader hold a torque screwdriver instead of a wrench.

The PC cable completes the chain on the data side. It connects the TTC610 digital indicator to a computer, so results can go straight into a record. As a result, the team spends less time copying numbers by hand.

Key features of the torque tester accessory TTC3421

The details below explain how each accessory extends the tester you already own. They also show what to check before you add a new mount, kit, or cable to your bench.

• Built for the Versatest® system. Every item in this family belongs to the Snap-on Versatest® electronic torque tester line. Therefore, the parts fit the loader, transducers, and indicator that the system uses.
• Screwdriver testing kit. The TTC75006 kit adapts the VERSATEST600 loader system for torque screwdrivers. So the same test bench can check both torque screwdrivers and click wrenches on one shared setup.
• PC link for the indicator. The TTC501 cable connects the TTC610 digital indicator to a PC. As a result, test readings can move into a computer file instead of a paper log.
• Low-range transducer mount. The TTC3421 mount suits transducers from 5 to 50 in-oz up to 80 to 1,000 in-lb. That covers fine screwdrivers and small wrenches used on light assembly work.
• High-range transducer mount. The TTC3422 mount suits transducers from 10 to 125 ft-lb up to 60 to 600 ft-lb. In addition, it covers the larger click wrenches found in most service shops.
• Lifetime warranty on some items. Snap-on lists a lifetime warranty on materials and workmanship for the kit and the PC cable. Meanwhile, the transducer mounts are listed as field repairable.

Typical applications

A torque tester accessory earns its place when one bench must test many tool types and torque ranges each week. The tasks below are the most common uses we see from buyers.

• Testing torque screwdrivers. Assembly lines use many preset and adjustable torque screwdrivers. With the screwdriver testing kit, the VERSATEST600 loader checks them on the same bench as the wrenches.
• Checking small click wrenches. Small wrenches for light fasteners need a low-range transducer. The TTC3421 mount holds those transducers firmly, so readings at the low end of the scale stay steady.
• Checking large click wrenches. Service shops use larger wrenches for wheels, engines, and frames. Therefore, the TTC3422 mount holds the larger transducers, up to the 60 to 600 ft-lb range.
• Logging results to a PC. Quality systems often ask for digital test records. The TTC501 cable links the TTC610 indicator to a computer, so results go straight into a file.
• Incoming tool inspection. Tool cribs often check new and returned wrenches before they go to the line. A Versatest® setup with the right mounts makes that check quick and consistent.
• Audit records for tool control. Auditors ask how a plant knows its torque tools still read correctly. Logged tester results give a clear answer, and the PC cable makes that log easy to keep.

Industries that use the torque tester accessory TTC3421

Any sector with a large fleet of torque tools needs a flexible tester setup. So these accessories show up in quality rooms, tool cribs, and workshops. Here is how each industry uses them in practice.

• Automotive manufacturing. Assembly plants check large fleets of torque wrenches and screwdrivers every month. In Vietnam, many FDI automotive and parts plants need fast tester setups and digital records.
• Electronics manufacturing. Electronics plants rely on torque screwdrivers for small screws on boards and housings. So a screwdriver testing kit helps plants in Bac Ninh and Thai Nguyen check them often.
• Aerospace maintenance. MRO teams must prove every torque tool reads within its tolerance. Therefore, a tester with proper mounts and PC records supports their strict tool control.
• Quality and metrology rooms. Inspection teams manage the testers that keep the whole plant's tools in check. In addition, the right mounts and a data link reduce setup time and copy errors.
• Fleet and service workshops. Truck, bus, and equipment workshops use many large click wrenches. Meanwhile, a high-range transducer mount lets them screen those wrenches quickly before each major job.
• Heavy equipment and energy. Mining, power, and construction sites use wrenches across wide torque ranges. Also, sites in Vietnam's industrial zones often keep a tester on hand for quick checks.

Torque tester accessory TTC3421 compared with similar brands

Before you buy, it helps to compare the torque tester accessory TTC3421 with other tester systems. However, the key question is not the part alone. Instead, it is whether the part fits the tester and indicator your team already runs.

If your team already runs a Snap-on Versatest® tester, these accessories are the simplest way to extend it. They fit the loader, transducers, and indicator you own. Even so, confirm current specs with each maker before you compare tester systems. Specifications change over time, so confirm current data with each maker before you decide.

Choosing the right model

• Start with the transducer you plan to use. Pick the TTC3421 mount for low ranges and the TTC3422 mount for higher ranges.
• Check that your loader system matches the kit before ordering. The TTC75006 screwdriver testing kit is listed for the VERSATEST600 loader system.
• Order the TTC501 cable if you need digital records. It connects the TTC610 digital indicator to a PC, so results go straight into a file.
• List every tool type your bench must test. That way, you can order all the mounts and kits at once and avoid improvised fixtures.
• Confirm the software and file format your quality system needs. Then plan how the PC will store and back up each test record.
• Read the warranty line on each product page. The kit and cable list a lifetime warranty, while the mounts are listed as field repairable.

For other sizes in the same range, compare Torque Screwdriver Testing Kit (for VERSATEST600 Loader System) – TTC75006, PC Cable – TTC501, Transducer Mount (10-125 ft-lb to 60-600 ft-lb) – TTC3422. Also browse the full Snap-on torque tools shop for handles, testers and adapters.

Care, storage and calibration

• Store mounts, kits, and cables in a dry drawer near the tester. Then the fittings stay clean and ready for the next changeover.
• Wipe each mount with a dry cloth after use. Also check the cable plugs for bent pins, because a poor contact can cause missing data.
• Keep the tester and its transducers on a 12-month calibration cycle, in line with ISO 6789 practice. We can arrange recalibration through an accredited laboratory.
• Never load a transducer beyond its rated range in any mount. Overload can damage the sensor, so stop and check any reading that looks wrong.
• Pack accessories in padded boxes when you move the tester between sites. In addition, keep them dry during the humid season to protect the metal parts.
