Wiha Hex L-Key Sets are made with ErgoStar, a mechanism that stores and conveniently organizes your L-Keys. Turning one L-Key in the holder makes all other keys turn to the side at the same angle, enabling you to remove the key you need quickly and comfortably. A clamping mechanism in the holder makes sure that the keys cannot fall out, regardless of whether the holder is open or closed. Each hex key consists of premium-quality tool steel and feature a satin finish for corrosion protection. The tips are fit with a chamfered end for smooth fastener engagement with CNC precision-machined tips for reduced cam-out.
