HONITON Hex Key Set - Ballpoint, 8pcs | 2.0-10 mm

New patented hex keys are designed to prevent slipping out of the bolt head damaging it. A perfect surface-to-surface adhesion multiplies torque and prevents further damage. TEXTURE: A dedicated research resulted in special texturing of the key (hardness of 58 HRC) which prevents the key from slipping out of the bolt head. EDGE CHAMFER: A new type of the key benefits from chamfered edge and sits in a bolt head perfectly tight for the whole time of operation. MULTIPLE ANGLED SURFACES: All keys come with many angled surfaces and chamfered edges to ensure proper contact with a bolt.
