Precision Stainless Steel Magnetizer Ring Kit

Two robust stainless steel magnetic rings, each weighing 12 g and machined to tight tolerances (±0.1 mm), provide repeatable, high-fidelity magnetization for hex-based tools. With a smooth, non-porous surface and no welds or seams, they resist oxidation and cleaning-agent degradation — suitable for both clean-room and workshop environments. When placed on a screwdriver shaft, the ring induces reliable magnetic polarity alignment in ferrous tool steel, allowing secure pickup and retention of screws up to 30 mm in length. The design avoids magnetic saturation or demagnetization risks associated with low-grade ferrite or neodymium-only solutions — delivering stable performance across thousands of use cycles.
