1/4" Hex Screwdriver Bit
Product Category: Tightening technology
Compliant with the ISO 2380 hex standard, the side length tolerance is controlled within ±0.03mm, perfectly matching M4-M6 screw slots. The torque transmission efficiency is 20% higher than that of Phillips screwdriver bits, enabling a stable maximum torque output of 15N·m. The rounded corner process reduces stress concentration, preventing slippage or screw stripping even when dealing with hard materials such as stainless steel and aluminum alloy, ensuring operational stability.
The main body is made of S2 alloy steel or chrome-vanadium steel, which achieves a hardness of HRC58-62 after quenching and tempering. It has excellent wear and impact resistance, with a service life 2.5 times that of ordinary steel materials. The surface nickel-plating or blackening treatment passes the 72-hour salt spray test, adapting to complex environments such as humidity and dust. The tail features a strong magnetic design (suction force ≥3N) to firmly hold screws, reducing the risk of parts falling during overhead or confined-space operations.
The 6.35mm universal interface is compatible with mainstream 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. The anti-slip knurling on the shank enhances grip stability, and laser-engraved specification markings with color-coded rings (e.g., blue for 1/4") facilitate quick identification.
Conclusion: The 1/4" hex screwdriver bit, centered on "precise fit, durability, and efficiency," meets the flexibility needs of household users while also handling industrial-level frequent operations. Its standardized design and performance balance make it an indispensable basic accessory in toolkits, combining practicality and cost-effectiveness.
