Semi-circular keys are made of high quality carbon steel, which not only have outstanding wear and corrosion resistance, but also can effectively resist the wear and environmental erosion in long-term use, prolonging the service life and reducing maintenance costs.
Advanced high-precision machining centres carry out the machining to ensure that the key dimensions are accurate and the surface is smooth and flawless. The semi-circular design provides high anti-sway stability and reduces the friction coefficient with the shaft groove, resulting in a smoother running and lower noise of the assembled drive system.
The product is carefully packaged in a sturdy plastic box, each piece of key is arranged in an orderly manner according to the size, with clear labels attached, for quick identification and easy access to improve work efficiency.
Widely used in automotive engines, industrial machinery, precision machine tools, agricultural equipment and other fields, it is a reliable choice for connecting rotary shafts and transmission components to achieve stable torque transmission. Whether for professional maintenance or personal DIY projects, it can be perfectly adapted to meet diversified needs.
The half-round key set, consisting of 80 pieces in 10 different sizes, is not only an indispensable tool on the workbench, but also an efficient solution to all kinds of assembly problems.
