Import Brushless Electric Screwdriver Srsd-02f — Buy in wholesale FOB from Supplier in China

The Srsd-02f is a brushless electric screwdriver designed for precision assembly work in manufacturing environments. The brushless motor architecture eliminates carbon brush wear, extending service life and maintaining consistent output torque across the duty cycle. Adjustable torque settings allow operators to match fastening force to specific joint requirements, reducing thread stripping and component damage. The tool runs on a rechargeable lithium-ion battery platform, with quick-charge capability to limit production downtime. Its lightweight housing and ergonomic grip profile target reduced operator fatigue during extended use on production lines.

Brushless DC motor technology in this class of screwdriver typically achieves efficiency ratings of 85-90 percent, compared to 75-80 percent for brushed equivalents, with commutation controlled electronically rather than mechanically. The absence of brush friction reduces heat generation and spark risk, an advantage in electronics assembly where ESD sensitivity is a concern. Lithium-ion cells of the type specified generally operate at 3.6V or 4.2V nominal per cell, with pack configurations commonly at 14.4V or 18V for handheld power tools. Standard industry practice for torque adjustment ranges in precision assembly screwdrivers spans 0.5 Nm to 6.0 Nm, with incremental detents or digital readouts for repeatability.

Primary buyers include OEM assembly contractors, electronics manufacturing services (EMS) providers, automotive tier suppliers, and furniture producers with captive fastening operations. The tool suits applications requiring controlled torque in clean assembly conditions, such as consumer electronics housings, automotive interior trim, and flat-pack furniture joints. Importers should confirm with Changshu Donglian whether the supplied charger supports local voltage standards (220V/50Hz in China versus 110V/60Hz in North America), and whether battery packs are shipped separately due to UN38.3 lithium battery transport restrictions. Response rate data for this supplier is currently unavailable, so direct enquiry is necessary to establish communication channels and confirm current production capacity.

Changshu Donglian Electric Appliance Manufacturing Co., Ltd is registered in Dalian, Liaoning Province, with postal code 116000, though its operational headquarters and manufacturing base are in Changshu, a city in Jiangsu Province known for its dense cluster of power tool and electric appliance manufacturers. The supplier holds a Harbor trust tier designation, indicating a baseline verification level on the platform. Response rate is recorded at 0.00 percent with zero average response hours, which means no response data is currently available to assess communication reliability. Buyers should initiate direct contact to gauge responsiveness and technical support capability before committing to orders.

The company profile does not disclose factory size, annual revenue, employee count, or specific clientele, and no manufacturing certifications beyond a general ISO claim are detailed in available data. The listing positions the Srsd-02f as a professional-grade brushless screwdriver, but does not specify whether the supplier designs and assembles the tool in-house or sources components from sub-contractors. Importers should request a factory audit or third-party verification report to assess production capability, quality management system scope, and R&D investment. The lack of response history suggests either a new listing or limited platform engagement, making due diligence particularly important.
