Hand tool selection guide

Whether there are turbid oil stains on the surface

When it comes to hardware products, it depends on whether the anti-rust technology is done. When purchasing, you can check whether the product will leave thick oil stains on your hands and whether your hands will be sticky. If you have this product, it is generally unqualified. In addition, it can be distinguished by the sense of smell. If the product has a pungent odor, there is usually an omission in the production.

Is the steel stamp clear

Hardware products are generally printed with brand words, labels, etc. Although small, most of the products produced by the factory use steel stamping technology, and the words are pressed before heat treatment. Therefore, the fonts are small but deep concave and very clear. The fonts of counterfeit products are relatively fuzzy. Due to the rough printing technology, the fonts float on the surface, and some of them can even be easily erased by hand.

Is the outer packaging clear

The factory brand has dedicated designers to design external packaging, and arrange production in factories that pass the production conditions. The packaging is very clear from lines to color blocks. Some imported brand accessories have unique designs on their packaging to protect intellectual property rights.

"Pick up ears" to listen to the sound

Shake the product to see if there is any noise. Most of the counterfeit products are under backward production conditions and are completely hand-crafted in workshops. Impurities such as sand will inevitably be mixed in the production process, which is hidden in the bearing body, so noise will be generated when rotating. This is the biggest difference from a genuine brand that strictly enforces production standards and uses machines to operate.
