Designed to the ISO 2380 hex standard with a side length tolerance of ±0.03mm, this bit perfectly matches M4-M6 screw slots, delivering 20% higher torque transmission efficiency than Phillips bits and a stable maximum torque output of 15N·m. The rounded corner design reduces stress concentration, preventing slippage or edge wear even on hard materials like stainless steel and high-strength alloys to ensure operational stability.

The 6.35mm universal shank is compatible with mainstream electric/manual tools such as Bosch and DeWALT. The quick-release buckle design enables bit replacement within 0.5 seconds, improving efficiency by 60% compared to traditional threaded connections. The knurled shank enhances grip, allowing precise force application even when wearing work gloves and reducing fatigue during prolonged use. Laser-engraved specifications and color-coded rings (e.g., blue for 1/4") facilitate quick identification.

With "precision, durability, and efficiency" at its core, the 1/4" hex bit meets the demands of professional technicians for high-intensity tasks while providing reliable support for DIY enthusiasts. Its standardized design and balanced performance make it an indispensable basic accessory in modern toolkits, widely used in all-scenario screw fastening tasks from home maintenance to industrial production.
