These industry examples are selection guidance, not additional manufacturer approvals.
Impact output does not establish the final joint torque. Follow the service procedure and verify final tightening with the specified torque method.
The table compares the listed model details. These are selection options, not confirmed replacements. Check the differences against your task and existing equipment.

Consider the complete power-tool setup, not just the headline drive or cutting size. For a pneumatic model, check the specified air supply, connection and hose requirements. For a cordless model, identify the battery platform and whether batteries and a charger are included. Then compare the space around the work, the working direction and the attachment required for the task. These checks help distinguish a practical configuration from a tool that only appears similar.
A quoted torque, speed or stroke value describes a particular characteristic; it does not replace the full operating instructions. Compare like measurements and avoid treating different ratings as equivalent. Also, a tool-only listing and a kit can share the same basic tool while supplying different equipment. Ask for the exact package contents. The electrical requirements of a charger and the supply requirements of an air tool need separate confirmation. Do not infer Vietnam mains compatibility from the product’s availability in an overseas catalogue.
Define the intended job in practical terms before comparing options. Record the equipment or component involved, the operation to perform and the access available around it. Include the current tool or accessory if this purchase replaces an existing item. That context helps distinguish a size change from a different product function. It also makes the application and industry examples above easier to assess against the actual work.
The official listing identifies this model as 3/8" Drive Impact Wrench (Blue-Point®). Its catalogue grouping is Impact Wrenches: 3/8" and 1/4" Drive / 3/8" Drive Heavy-Duty (Blue-Point®). Use that description to identify the product format, then read the individual specifications for the details that matter to the job. A category describes where the product sits in the range; it is not an additional compatibility approval.
For this record, the available specification labels include Free Speed, RPM; Length, inches (mm); Vinyl Boot. Read each value together with its label and unit. A drive size, external dimension and working range describe different things, even if their numbers look similar. If the job requires a value that is not listed, request that detail before ordering instead of estimating it from the photograph.
The catalogue country-of-origin field is TWN. This field concerns the listed product origin; it does not identify local inventory, delivery time or the warranty terms of a Vietnam quotation. Confirm those commercial details separately.
The comparison above names AT380A and AT351. Review the displayed differences against the requirement for this job. Begin with function and compatibility, then compare access, configuration and included components. If the names differ by size, drive, colour or kit format, identify which difference matters before making a choice. Similar models are not automatic replacements, and a larger or more expensive option is not necessarily the better match.
Ask for a line-item description of the supplied configuration. For a set or kit, confirm the contents; for a component, confirm the quantity and the matching parent model where relevant. If photographs show a larger assembly or several items, do not assume all of them form part of this SKU. Keep any essential accessories and documents explicit in the quotation so that receiving checks can follow the same requirements.
On receipt, compare the item and its packaging with the ordered model, quantity and configuration. Check the supplied components and any requested documentation. Keep the product identification visible in the workshop’s inventory record. If the delivered item differs from the confirmed order, resolve that difference before assigning it to the planned job. This is especially useful when a range contains visually similar sizes or accessories for different parent tools.
For continued use, follow the manufacturer’s instructions for inspection, cleaning, storage and maintenance. Do not assume that a cleaning chemical, lubricant or maintenance method used on another tool is suitable here. Keep damaged or uncertain equipment out of the planned task until its condition is assessed. Record any replacement parts by model so future orders use the confirmed reference rather than a visual guess.
Send Techmaster Vietnam the model number AT370 and details of your task or existing equipment. Include any required sizes, connections and accessories. This helps identify the correct configuration.
Before ordering, confirm the quotation, lead time, package contents and applicable warranty terms. The official catalogue is the technical reference; it does not establish local stock or a Vietnam selling price.
