Technical Specifications to Verify

When evaluating manual mini hexagonal screwdrivers, the blade geometry and handle ergonomics are the primary technical considerations. Buyers should verify the drive size and blade diameter, with common specifications including 2.5mm blade diameters and lengths of 40mm, as seen in models like CTSDH25100. The screw head type is specified as HEX, which requires precise manufacturing to ensure a snug fit and prevent stripping of the screw head during use. The handle material is often listed as plastic or polypropylene, and buyers should assess the grip comfort and durability, especially if the tool is intended for prolonged professional use. Additionally, the finishing process, such as nickel plating or carbon steel treatment, impacts corrosion resistance and aesthetic appeal, so verifying the specific finish applied to the blade is essential for longevity.

For cordless and electric variants, electrical and mechanical specifications become paramount. Key parameters to verify include the battery type, such as a 3.6V 850mAh lithium battery, and the charge time, which is often cited as 30 minutes. The operating time under no-load conditions, typically around 60 minutes, and the torque adjustment settings, which may range from 1.5Nm to 2Nm in electric mode and up to 10Nm in manual mode, define the tool's performance envelope. Buyers must also check the physical dimensions, such as the single package size of 10x4x3 cm or 14x4x4 cm, to ensure compatibility with retail packaging and storage logistics. The rotation speed, whether 220 RPM or 280 RPM, should be matched to the intended application, as higher speeds may not always equate to better performance for delicate tasks.

Compliance and Safety Documentation

Safety documentation for powered screwdrivers is a critical component of the procurement process, particularly concerning electrical safety and battery handling. Buyers should request evidence of compliance with relevant electrical safety standards, such as IEC 60745 for hand-held motor-operated electric tools, although specific certification status should be verified directly with the supplier. The inclusion of a lithium battery introduces additional regulatory requirements, including transport safety guidelines for lithium-ion cells and potential recycling mandates. Suppliers should provide clear instructions for charging, such as the specified 5V 500mAh USB charger input, and warnings regarding overcharging or improper disposal to mitigate fire hazards and ensure user safety.

For manual screwdrivers, safety concerns are primarily related to mechanical integrity and material toxicity. Buyers should verify that the carbon steel blades meet appropriate hardness and tensile strength standards to prevent breakage under torque. The plastic or polypropylene handles should be free from sharp edges and made from non-toxic materials, especially if the tools are intended for consumer use or sold in regions with strict chemical regulations. While specific certifications like CE or RoHS are not explicitly confirmed in the provided data, buyers should inquire about the presence of these marks to ensure the products comply with international trade requirements. Clear labeling of the product model, origin, and manufacturer details is also essential for traceability and post-sale support.

Cost Drivers and Commercial Terms

The cost of mini hexagonal screwdrivers is influenced by several factors, including material costs, manufacturing complexity, and order volume. For manual tools, the primary cost drivers are the price of carbon steel and plastic, as well as the labor involved in assembly and finishing.
