Feature
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.
🌟 Additional Feature Update
- Exclusive SNCMVH Alloy Tip – Manufactured in Taiwan, engineered to exceed S2 and Cr‑V hardness.
- Longer Life Cycle – SNCMVH shows less tip deformation and edge chipping, even under repetitive torque stress.
- Professional Benchmark – Surpasses the performance of leading competitor tips made from S2 or tool-grade Cr‑Mo.
