SPECIFICATION:
Material: Carbon Steel
Size: 10x3x3mm/0.39x0.12x0.12 inch (L*W*H)
Color: Silver
Package Included: 28Pcs x Round Ended Feather Key

Durable and Reliable: Crafted from hardened carbon steel, this parallel key features exceptional compressive strength, wear resistance, rust prevention, corrosion resistance, and does not break easily. It resists shearing and deformation under high torque loads, providing long-lasting reliability for mechanics and technicians repairing machinery in industrial workshops.

Precision Fit: This key features a double-rounded head design with a smooth, burr-free surface, allowing it to fit snugly into the keyway of the shaft and hub, minimizing transmission backlash and ensuring stable torque transmission and precise operation. The double-rounded head structure also facilitates installation into the keyway, enabling maintenance technicians to quickly assemble and disassemble components within tight maintenance schedules, efficiently replacing worn parts.

Wide Application: This woodruff key stock is a common positioning fastener used in mechanical drive systems to connect shafts to hubs—such as those for motors, gears, sprockets, and pulleys—and to transmit rotational torque. It is widely used in applications including automotive engines, go-karts, lawnmowers, tractors, small generators, machine tools, industrial machinery, agricultural equipment, pumps, valves, and DIY mechanical modifications.

Note: Before purchasing, please verify the width, height, and length specifications of the keyways on the shaft and hub; mismatched specifications will result in transmission failure. Do not exceed the rated torque load, as overloading can lead to shear failure.
