1/4"-24 Phillips Thread Screwdriver Bit
Product Category: Tightening technology
Specifically engineered for Unified National Coarse (UNC) threads, the 1/4"-24 Phillips screwdriver bit features a nominal diameter of 1/4 inch (approx. 6.35mm) with 24 threads per inch. Ideal for electronic device assembly, small machinery repair, and household appliance installation, it ensures precision and durability in diverse applications.
Adopting the ISO standard #2 Phillips cross recess, the bit maintains a ±0.05mm tolerance for perfect alignment with screw slots. This design enhances torque transmission accuracy by 20% compared to standard bits, reduces slippage by 28%, and minimizes screw stripping and bit wear.
The tetrahedral pyramid tip design penetrates deeply into screw recesses, leveraging curved surface stress dispersion technology to distribute force evenly. This ensures stable operation even on high-hardness alloy screws. A built-in magnetic ring (≥2.5N holding force) securely holds 1/4"-24 screws, preventing drops during overhead or confined-space work. Anti-static coated models (static dissipation time <0.1 seconds) safeguard sensitive electronic components from electrostatic damage, making them ideal for semiconductor installations.
Crafted from S2 alloy steel or chrome-molybdenum-vanadium steel and heat-treated to HRC 58-62, the bit offers exceptional wear and impact resistance. The shank is laser-engraved with "1/4"-24 PH2" and features an orange coding ring for quick identification. The 6.35mm universal shank fits 主流 power tools like Bosch and DeWALT, while a quick-release design enables 0.5-second bit changes—45% faster than traditional threaded connections—optimizing efficiency for professionals and DIYers alike.
