• 【Material】: Crafted from premium materials (such as 304 stainless steel or carbon steel) to ensure maximum strength, durability, and corrosion resistance.
• 【Rounded Corner Design】: Features a standard rounded corner structure for quick installation, primarily used to secure wheels or pulleys onto the main shaft of a hub. During operation, torque is transmitted through contact between the keyway side, shaft groove side, and hub groove side.
• 【Complete Size Range】: Available in various sizes from 8 mm to 30 mm, including M3, M4, M5, M6, and more, compatible with diverse equipment and machinery.
• 【Easy Installation】: Minimalist design for effortless assembly and disassembly. Rectangular body with rounded ends eliminates complex structures, enabling swift installation/removal ideal for equipment requiring frequent maintenance or disassembly.
• 【Versatile Applications】: Round-head keys primarily secure and release equipment by aligning with keyways to transmit torque between shafts and hubs or bushings. They serve machinery, automotive systems, industrial equipment, and power transmission applications requiring precise, reliable rotational connections.
