Size & Package - The key stock has a length of 20 mm / 0.79", a width of 4 mm / 0.16", and a thickness of 4 mm / 0.16". The packaging includes 10 pcs round-ended feather keys to meet your project requirements Material - The machine keyway is made of carbon steel with precision machining, which has good wear resistance, corrosion resistance, and oxidation resistance. It does not require washers or grinding, making it a good part for most mechanical equipment maintenance or replacement Feature - The round key stock is designed for fastening the frequent disassembly equipment. It transmits torque between the shafts and hubs or bushings by matching the keyway. The high torque transmission capacity and uniform load distribution along the shaft effectively prevent relative sliding or rotation and ensure the stability of the mechanical structure Easy to Install - The parallel drive shaft keys are easy to install. You only need to insert the key into the gap between the shaft and the hub. During operation, the torque can be transmitted through the contact between the side of the key and the side of the shaft groove and the hub groove, ensuring that the two rotate synchronously Widely Applicable - The feather key is suitable for machinery, automotive applications, industrial equipment, power transmission systems, and other mechanical systems that require the precise coupling of rotating parts. They are usually used in shaft key sets of equipment, such as machine tools, pulleys, axles, and replacement parts for garden equipment or lawn mowers Description:
