Product Advantages

Plastic Clip Packaging: Each wrench is secured with a transparent plastic clip, arranged neatly for easy carrying and storage, and all specifications are clearly visible for quick access.

Mirror Polishing: The wrench surface is precision polished to achieve a mirror effect, which is not only aesthetically pleasing but also easy to clean of oil stains, and has better rust prevention than ordinary blackening treatment.

Double-ended opening design: Each wrench has different opening specifications at both ends (e.g., 6x7mm), making it two-in-one and reducing the number of tools required. The opening fits precisely with the bolt head, preventing slippage.

Full Specification Coverage: From 6mm to 24mm, a total of 8 combinations, capable of handling bolts and nuts from M4 to M16, covering household and general industrial maintenance needs.

Standards: Complies with QB/T3001, which has strict regulations on the hardness, torque, and opening precision of wrenches.
