FAQ:

Q1: What are the advantages of 40Cr steel over standard carbon steel?

A: 40Cr is a high-grade chromium-alloy steel. Combined with integral high-temperature quenching, it provides significantly higher tensile strength, impact toughness, and resistance to deformation compared to ordinary carbon steel.

Q2: Why is the 3.5mm hex key included in this set?

A: While standard sets often skip half-sizes, 3.5mm is essential for specialized machinery, specific European bicycles, RC models, and precision electronics, making this set more versatile.

Q3: Does the galvanized treatment prevent rust?

A: Yes. The electro-galvanized coating forms a protective barrier against moisture, oxidation, and oil corrosion, ensuring a long shelf life and clean appearance.

Q4: Do you offer private label and custom packaging for OEM orders?

A: Yes, we provide complete OEM/ODM solutions, including custom branded packaging, laser-etched logos, and customized holder colors. Typical lead times are 20–30 days.
