The 1/4" hex bit, with its standardized specifications and outstanding performance, has become a frequently used tool in scenarios such as home maintenance and industrial assembly. It strictly adheres to the ISO 2380 hex standard, with the side length tolerance precisely controlled at ±0.03mm, allowing it to closely engage with M4-M6 screw slots. Its torque transmission efficiency is 20% higher than that of ordinary bits, capable of stably outputting 15N·m of torque, and easily handling the screwing of materials such as aluminum alloy and stainless steel.

The bit is forged from one-piece S2 alloy steel. After quenching and tempering, its hardness reaches HRC58-62, featuring excellent wear and impact resistance, with a service life 2.5 times that of ordinary steel bits. The nickel-plated surface passes the 72-hour salt spray test, providing excellent rust resistance and enabling stable use in humid and dusty environments. Some models are equipped with a strong magnetic ring (suction force ≥3N), which can firmly hold screws and reduce the risk of parts falling during operations in narrow spaces.

The 6.35mm universal interface is compatible with mainstream electric and manual tools from brands like Bosch and DeWALT. The quick-release buckle design enables bit replacement within 0.5 seconds, significantly improving work efficiency. The anti-slip knurling design on the shank conforms to ergonomics, making it less prone to fatigue even during long-term operation. The laser-engraved specification markings and blue coding rings facilitate quick identification and access. From furniture assembly and home appliance repair to screw fixing in electronic product production lines, the 1/4" hex bit meets diverse work requirements with its characteristics of "precision, durability, and efficiency," and is an essential basic accessory in modern toolkits.
