0390SQ Square-Head Screwdriver – SNCMVH Tip, Cr‑V Shaft, Cushion Grip

0390SQ Square-Head Screwdriver is built for maximum durability with an exclusive SNCMVH alloy tip—engineered in Taiwan to outperform S2 and Cr‑V. This premium-grade steel delivers exceptional torsional strength and wear resistance, especially valued in professional applications like electrical panels, cabinetry, and machinery maintenance.

Unlike standard Cr‑V or S2 screwdrivers, the SNCMVH tip resists rounding and cam-out under heavy torque. Combined with a cushion-grip handle, Cr‑V chrome-plated shaft, and magnetic head, the 0390SQ delivers a superior tool experience built for lifetime reliability.
