Dual Fastening Profiles (PH2 & SL6): Integrates an induction-hardened PH2 Phillips head and an SL6 (6.0mm) flat-slotted tip on one shank for instant tool-free switching.
Hardened Chrome-Vanadium (Cr-V) Steel: High-tensile alloy steel construction resists bending, rounding, and torsional stress during stubborn screw extractions.
Positive Detent Retention Handle: Quick-release locking collar grips the reversible shaft firmly to prevent axial slippage and bit play under high torque.
Ergonomic High-Traction Grip: Contoured handle maximizes hand leverage and downward thrust while resisting shop oils, grease, and moisture across job sites in Nepal.
