High quality Hex Key set for hexagonal socket screws in a practical clip fastener out of wear-resistant material, enabling secure storage of the L-keys as well as simple removal. Hex Keys with Hex-Plus profile: offers a larger contact surface within the screw head.

The tools are quickly to hand thanks to the laser-engraved and thereby wear-resistant size markings on the hex keys.
