This bit strictly adheres to relevant industry standards. The 1/4" square drive interface ensures a tight engagement with tools, delivering efficient and stable torque transmission. Compared with ordinary interfaces, its torque transmission efficiency is increased by 20%, capable of stably outputting 10N·m of torque to easily handle various screw fastening tasks. The main body is forged from high-quality S2 alloy steel in one piece. After quenching and tempering, it achieves a hardness of HRC58-62, with excellent wear and impact resistance—its service life is 2.5 times that of ordinary steel bits. The surface is nickel-plated and passes the 72-hour salt spray test, featuring strong rust resistance and adapting to complex working environments such as humidity and dust.

The square drive design is its core highlight. Compared with traditional interfaces, this structure better distributes torque evenly, effectively reducing slippage and the risk of damage to connecting parts, especially suitable for long-term and high-intensity operations. The 6.35mm standard interface is compatible with various brands of tools such as Bosch and DeWALT. The quick-change design enables rapid bit replacement within 0.5 seconds, significantly improving work efficiency. The shank is treated with anti-slip knurling, designed ergonomically for comfortable and stable grip. The surface is laser-engraved with clear specification markings, facilitating quick identification in complex tool environments. Whether for daily home maintenance or batch assembly work in professional workshops, the 1/4" square drive bit meets diverse work requirements with its characteristics of "strong adaptability, high durability, and easy operation".
