The Proskit HW‑122M is a compact, durable folding hex key set for metric sizes from 1.5 to 8 mm, ideal for mechanics, electronics, DIY kits, bicycle maintenance, and tight‑space access. The design folds like a Swiss Army knife for portability and includes a three‑color, non‑slip ABS/TPE shell to improve grip and prevent losing tools. The keys are made of Cr‑V special steel with hardness high enough for reliable torque with minimal rounding. Packaged on a hanger card.
