Featuring an ISO 2380-standard hexagonal structure with a side length tolerance of ±0.03mm, this bit ensures a precise fit with M4-M6 screw slots. Its torque transmission efficiency is 20% higher than Phillips bits, thanks to the tight hexagonal engagement. The rounded corner design reduces stress concentration, allowing the bit to withstand a maximum torque of 15N·m. This minimizes slippage caused by edge wear in traditional bits and prevents screw stripping, making it ideal for hard materials like stainless steel.​
Household Use​
Securing furniture hardware (e.g., wardrobe hinges, table leg screws).​
Repairing home appliances (e.g., removing appliance casings).​
Industrial Use​
Fastening screws on electronic device production lines (compatible with automated screwdrivers).​
Installing small mechanical components in industrial machinery.​
Special Designs​
Short-shank model (25mm total length): Optimized for confined spaces with limited accessibility.​
Extended-shank model (150mm total length): Suitable for deep-hole operations requiring extra reach.​
Interface and Efficiency​
The 6.35mm interface is compatible with global mainstream tool systems, including electric screwdrivers, pneumatic tools, and manual ratchet wrenches from brands such as Bosch and DeWALT. The quick-release buckle design enables bit replacement in 0.5 seconds—60% faster than traditional threaded connections—significantly streamlining operation time.​
Conclusion: With its core principles of "universality, durability, and efficiency," the 1/4" hex bit caters to both the lightweight needs of daily household repairs and industrial-grade high-frequency tasks. It remains an indispensable basic accessory in any tool kit.
