Frequently Asked Questions
Q: What is the benefit of the Wiha MagicRing?
A: The MagicRing is a specialized steel spring compression ring integrated into the ball end of the hex key. It securely holds the screw to the tool, making it significantly easier to insert or remove fasteners in hard-to-reach areas without dropping them.
Q: Can these hex keys turn screws at an angle?
A: Yes, the ball end geometry allows for fastener interlock and rotation at angles up to 25 degrees, providing better access in confined or awkward spaces.
Q: Are all the keys in this set equipped with the MagicRing feature?
A: No, the MagicRing feature is included on metric sizes from 3.0mm to 10.0mm, and SAE sizes from 1/8" to 3/8". The smaller keys utilize a standard ball end.
