Key Features & Technical Specifications
- Material Excellence: 45# medium-carbon steel provides a perfect balance of hardness and toughness, ensuring the keys resist bending or breaking under high torque.
- Heat Treatment: Each key undergoes a controlled quenching and tempering process to achieve a consistent hardness of HRC 48–52, offering wear resistance without brittleness.
- Precision Machining: The hexagonal tips are accurately cut to tight tolerances (ISO 4762 or DIN 911 standard) for a secure fit in fastener sockets, reducing stripping and slippage.
- Ergonomic Design: L-shaped configuration with a long arm for leverage and a short arm for confined spaces. The ends are chamfered for smooth insertion.
- Surface Treatment: Bright plain finish with anti-rust oil coating; black oxide finish is available upon request for enhanced corrosion resistance.
- Complete Size Range: The set typically includes 14, 15, 16, 17, 18, 19, 20, 22, 24, 27, 30, 32, 36, 41, 46, 50 mm (customized size combinations are welcome).
