Adhering to the ISO 2380 standard hexagonal structure, this 1/4" hex screwdriver bit maintains a side length tolerance of ±0.03mm, ensuring a perfect fit with M4-M6 screws. Its torque transmission efficiency is 20% higher than that of Phillips bits. The rounded corner design reduces stress concentration, allowing the bit to withstand a maximum torque of 15N·m. This effectively prevents slippage caused by edge wear of traditional bits and screw stripping, making it especially suitable for hard materials such as stainless steel.

The bit features a strong magnetic tail design (magnetic force ≥3N), which securely holds screws, minimizing the risk of parts falling during overhead or confined-space operations. The shank is equipped with an anti-slip knurling process, enhancing grip comfort and reducing hand fatigue. Specifications are laser-engraved on the bit, accompanied by a color-coded ring (blue represents 1/4" for easy identification).

The 6.35mm interface is compatible with mainstream global power tools, including electric screwdrivers, pneumatic tools, and manual ratchet wrenches from brands like Bosch and DeWALT. The quick-release buckle design enables bit replacement within 0.5 seconds, improving efficiency by 60% compared to traditional threaded connections.

Applications:

Household Use: Ideal for furniture assembly (such as wardrobe hinges and table leg screws) and home appliance repair (removing appliance casings).
Industrial Use: Suitable for screw fastening on electronic device production lines and installation of small mechanical components, compatible with automated screwdrivers.
Special Designs: The short-shank version (25mm total length) is designed for narrow spaces, while the extended-shank version (150mm) meets the needs of deep-hole operations.

In summary, with its characteristics of "precision, durability, and efficiency," the 1/4" hex screwdriver bit has become the top choice for professional technicians and DIY enthusiasts when handling medium to high-intensity tasks. It is an indispensable basic accessory in modern toolkits.
