Designed to ISO 2380 hexagonal standards with a side length tolerance of ±0.03mm, this bit ensures a perfect fit with M4-M6 screw recesses. It delivers 20% higher torque transmission efficiency than Phillips bits and stably outputs a maximum torque of 15N·m. The rounded corner design reduces stress concentration, preventing slippage or screw stripping caused by edge wear, making it ideal for hard materials like stainless steel and aluminum alloy.

Constructed from S2 alloy steel or chrome-vanadium steel, heat-treated to HRC 58-62 hardness, it offers exceptional wear and impact resistance. Surface treatments (nickel plating or black oxide) pass 72-hour salt spray tests, ensuring durability in humid or dusty environments. A magnetic tip (≥3N holding force) securely holds screws, minimizing drop risks during overhead or confined-space operations.

The 6.35mm universal shank fits 主流 power tools (Bosch, DeWALT, etc.), featuring a quick-release chuck for 0.5-second bit changes—60% faster than threaded connections. Knurled grips enhance control, while laser-engraved markings and color-coded rings (blue for 1/4") enable quick identification.

Summary: Engineered for "precision, durability, and efficiency," this bit excels in both household DIY tasks and industrial applications. Its versatility and cost-effectiveness make it an essential tool for any toolkit.
