Designed to strictly adhere to the ANSI/ASME B1.1 Unified Thread Standard, this Phillips screwdriver bit perfectly matches 12-24 thread screws with a precisely controlled engagement depth of 0.8-1.2mm. It delivers 15% higher torque transmission efficiency than standard Phillips bits, stably outputting 8-12N·m to prevent slippage or screw damage—ideal for high-precision applications such as automotive components and pump valve assemblies.

Forged from premium S2 alloy steel in one piece, it undergoes vacuum quenching and triple tempering to achieve a hardness of HRC56-58, enhancing impact resistance by 30% and enduring over 30,000 cycles of repeated use. The surface is treated with a 25μm electroless nickel-phosphorus plating, passing 100-hour salt spray testing with rust resistance twice that of conventional coatings, making it suitable for harsh industrial environments involving oil, moisture, or chemicals. Laser-etched anti-slip textures on the blade increase friction with screw slots, improving operational stability.

Conclusion: Engineered for the Unified Thread System, this 12-24 Phillips bit excels in precision, durability, and professional-grade performance. Its comprehensive material and design optimizations make it the trusted choice for professionals working with 12-24 threaded components, particularly in industrial settings demanding exacting torque control and tool longevity.
