Designed to ISO 2380 hexagon standards with a side length tolerance of ±0.03mm, this bit perfectly matches M6-M8 screw recesses. It delivers 30% higher torque transmission efficiency than Phillips bits and withstands up to 22N·m of torque. Reinforced edges and rounded corners reduce stress concentration, preventing slippage or wear on hard materials like alloy steel and high-strength bolts for consistent performance.
Constructed from S2 alloy steel or chrome-molybdenum-vanadium steel, heat-treated to HRC 58-62 hardness, it resists wear and impacts. Surface treatments (black oxide or nickel plating) pass 96-hour salt spray tests, ensuring durability in harsh environments like damp workshops or outdoor sites. Select models feature a magnetic tip (≥4N holding force) to securely hold screws, minimizing drop risks during overhead or confined-space work.
The 7.94mm standard shank fits 主流 power wrenches, pneumatic tools, and manual ratchets (e.g., DeWALT, Milwaukee). A quick-release chuck enables 0.8-second bit changes—50% faster than threaded connections—while knurled grips enhance control even with work gloves, reducing fatigue during prolonged use.
Engineered for "durability and efficiency," this bit meets professional demands in heavy-duty applications and supports serious DIYers, making it ideal for medium to large-scale fastening projects.
