BODY: In this 15-second walkthrough, you'll see our precision production lines for hex keys, staple guns, and screwdriver sets.

Our 25-engineer R&D team and 450 skilled workers ensure every tool meets CE and GS standards for global markets. Q: How is a hex key manufactured to achieve HRC 52-55 hardness? A: Hex keys are cold-forged from CR-V 6150 steel, then hardened and tempered to HRC 52-55. Each batch undergoes torque testing from 0.82N to 220N to ensure durability and precision. Final products are inspected for ball-end geometry and surface finish before packaging.
