It locks into a matching half-moon keyway machined into the shaft and engages a longitudinal slot in the mating hub, preventing the two from rotating independently and ensuring precise alignment during operation. At ANSI key number 806, this is a standard imperial-size key widely used across agricultural, lawn and garden, and small engine applications including tractors, mowers, and outdoor power equipment. The key is also designed to act as a fail-safe: under severe overload (such as a blade strike), the key shears before damage occurs to costlier engine or drivetrain components.\u003c\/p\u003e\u003ch4\u003eSpecifications\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003eWidth: 1\/4 in.
